Description

Land value information management system and ecosystem guidance method

The present invention relates to a system for managing land value information and an ecosystem guidance method.

In recent years, interest in global environmental conservation has increased, and ecosystems that include multiple organisms have come to be evaluated as valuable natural capital. However, the factors that influence the nature of outdoor ecosystems are diverse and complex, and even the latest science does not always understand them. For this reason, conventionally, when evaluating the value of an ecosystem, the ideal state of the ecosystem "in the state of being originally constructed in the natural environment" is sought, and the value of the ecosystem is evaluated based on that state.

However, there are various ways of outdoor ecosystems, and their economic value is difficult to quantify. Therefore, we create a database of the value of the ecosystem that can grasp the state of a certain vegetation as a characteristic, and use the state of the vegetation in a certain area as an input value to derive the value of the ecosystem of the vegetation that has characteristics similar to the input vegetation. Therefore, a method for calculating the value of the ecosystem in the area has been proposed (Patent Document 1).

Patent Document 1 also discloses a method for calculating the value that an ecosystem will create in the future. Further, Patent Document 2 proposes an ecosystem evaluation method that contributes to efforts to improve the value of the ecosystem. While ecosystems are being evaluated as valuable natural capital, methods for quantifying the value of ecosystems and methods for improving the value of ecosystems have been proposed.

JP-A-2019-117613 Patent No. 6017318

However, the ecosystem value evaluation method disclosed in Patent Document 1 evaluates the benefits provided by the ecosystem in the "state originally constructed in the natural environment" as economic value. In addition, the method of finding the future value is to predict the future value by changing the "originally constructed state" with time toward the future, and there is an idea of artificially manipulating the composition of the ecosystem. Not done.

On the other hand, the ecosystem evaluation method disclosed in Patent Document 2 evaluates the influence of artificial efforts to increase the value of the ecosystem. The evaluation method disclosed in Patent Document 2 evaluates the potential and actual value of the ecosystem that can be constructed in the area to be evaluated at the time of evaluation, and when this evaluation value is above a certain level, the evaluation value is evaluated. It artificially works on the local ecosystem and evaluates its activities.

By the way, the state of the ecosystem in the field is constantly changing due to complicated intrinsic and extrinsic factors, and the whole process has not been scientifically elucidated yet. For this reason, it has been considered difficult to artificially design an outdoor ecosystem and scientifically control its state even with cutting-edge science. Therefore, the conventional method for improving the value of an ecosystem is predicted from the present by "forecast" thinking based on the state of the ecosystem obtained at the time of evaluation and the evaluation thereof, as in the method disclosed in Patent Document 2. Future value improvement measures are set.

For such a situation, research results evaluated as the beginning of scientifically controlling the ecosystem have been published (Non-Patent Document 1). The research results disclosed in Non-Patent Document 1 identify microorganisms (referred to as "core symbiotic microorganisms") that influence the function of the entire microbial flora, strengthen the symbiotic relationship between the core symbiotic microorganisms and plants, and desire them. Functional plants-inducing microbial ecosystems.

The present inventor has found that by using the research results disclosed in Non-Patent Document 1, the value of the ecosystem can be improved by the "backcast" thinking of setting the ecosystem to be guided first. The present inventor further uses "backcast" thinking to set what kind of appearance composition and what kind of economic value the ecosystem should be, and by inducing the set ecosystem, the abandoned cultivated land. We have found that it is possible to improve the economic value of land that has low utility value, such as abandoned forests and abandoned forests, and completed the present invention.

The present invention provides a method for improving the economic value of land with low economic value by redefining, redesigning, and reconstructing an outdoor ecosystem by backcast thinking.

In addition, an ecosystem in a certain state originally exists in the open air. Therefore, in the present specification, evaluating an ecosystem that originally exists in this way for an artificial purpose or a specific sense of value is referred to as "redefining the ecosystem". Then, it is expressed as "redesigning" to examine and determine the composition of an ecosystem that meets an artificial purpose or a specific sense of values by backcast thinking with respect to the originally existing ecosystem. Furthermore, putting an originally existing ecosystem into a state of being "redesigned" by backcast thinking is expressed as "reconstructing" or "inducing".

The present invention provides an information management system used to induce an ecosystem set by backcast thinking and improve the value of land, and an ecosystem induction method capable of improving the economic value of land. The present invention specifically provides a system for managing the economic value information of land by inducing a redesigned ecosystem. The information management system according to the present invention has an area that can be used for some economic activity (generally 50 square meters or more, particularly 100 square meters or more), and obtains a desired economic value for land that can be independently subject to land transactions. Redesign the ecosystem that can be created, and memorize the information for grasping the state of the ecosystem in the process of its reconstruction and the economic value in that state. Information for grasping the state of the ecosystem includes information indicating the physicochemical and biological conditions of the ecosystem. In addition, "ecosystems that can create desired economic value" include, for example, agricultural land and forest ecosystems that produce crops and flowers that are traded at the desired amount, parks and admission sites that have the desired economic value, etc. As an example, an ecosystem that can be used as a stage for "sixth industry" including processing and tourism as well as primary industry can be exemplified.

According to the present invention, in the process of redefining an ecosystem already existing in a certain land, redesigning the ecosystem so as to achieve a desired economic value, and guiding the redesigned ecosystem to the land. Record the economic value in the state of the information management system. This facilitates the confirmation that the redesigned ecosystem is properly reconstructed and streamlines the process of increasing the economic value of the land by inducing the redesigned ecosystem.

Here, if you refer to the database on the flora and fauna that can live in the land for which you want to design the ecosystem, you can more easily redesign the desired ecosystem. In addition, the optimal ecosystem can be redesigned from a complex and bird's-eye view.

In particular, when redesigning the ecosystem, if the soil of the target land or the plants growing in that soil are analyzed, thousands to tens of thousands of species of microorganisms (underground microbial flora and plant symbiotic microbial flora) inhabiting that land can be analyzed. ) Can be grasped. Then, if the ecosystem is redesigned by utilizing those microbial flora by the technology disclosed in Non-Patent Document 1, the ecosystem reconstruction process can be accelerated more efficiently.

In particular, by regularly analyzing the underground microbial flora and plant symbiotic microbial flora in the process of reconstructing the ecosystem, it is possible to grasp the state of induction to the target ecosystem and efficiently reconstruct and maintain the target ecosystem. Can be managed. The target ecosystem may be redesigned and then modified as necessary.

In addition, when the right holder redesigns the ecosystem for different adjacent land, the redesign and guidance management of the ecosystem collectively targets the adjacent land, while the distribution of interests based on the land right is for each right holder. It is good to be able to do it. As a result, the gap between the artificially defined land boundary and the boundary setting for redesign, reconstruction, and maintenance, which is considered to be appropriate from an ecological point of view, can be eliminated.

According to the present invention, the economic value of land with low economic value can be improved by redesigning the ecosystem by backcasting and reconstructing the designed ecosystem.

You may build it so that you can. The land value information management system 1 may be constructed as a plurality of physical servers (clusters) or as virtual servers in a cloud environment.

In the management system 1 of the present embodiment, data and instructions from each client are input from each device 20 to the front end 100 via the UI, and processing, storage, reference, etc. of necessary data based on the instructions are performed by the back end 200. Will be executed. The information output from the back end 200 may be sent to the device 20 of each client via the front end 100 and the UI and displayed on the display unit, and may be stored in the DB server 2500. For input / output of information, a storage medium such as a memory card or USB that can be directly connected to the server may be used. In that case, the UI does not necessarily have to be implemented on the Web server, and the client may be designed to directly input / output information to / from the AP server and the DB server.

The DB server 2500 in the business server group 10 conceptually includes a land information DB 2510 as an attribute information storage unit, a value information DB 2530 as a value information storage unit, an ecosystem information DB 2550 as an ecosystem information storage unit, and an ecosystem regeneration.

<Outline of information management>
An information processing method for managing land value information using this management system 1 will be described with reference to FIG. The client of the management system 1 uses the device 20 to input initial information about the land to be redesigned for the ecosystem (S1). As the initial information, at least the location of the target area and its economic value (initial value) are input. It is preferable to input information on the area of the target area, the right holder, etc., and information on the state of the ecosystem at the present time (at the time of redesign) of the target area (ecosystem state information). The input information is held in any of the land information DB 2510, the value information DB 2530, and the ecosystem information DB 2550 in the DB server 2500 as a record for the target area. Specifically, information on land attributes (location, area, right holder, etc.) is retained in land information DB2510, information on land value is retained in value information DB2530, and information on ecosystem is retained in ecosystem information DB2550. good. Further, a target area ID for uniquely identifying the target area is assigned to each target area (see FIG. 3), and the target area ID is treated as a primary key for uniquely identifying the target area.

When the initial information of S1 is input and the business server group 10 receives the request for redesigning the ecosystem to be reconstructed in the target area, the design unit 2110 refers to the design DB 2570 and a plurality of capable grows in the target area. Extract the organisms of. This management system 1 uses a design DB 2570 in which information on an ecosystem redesign model for an arbitrary target area is stored. Specifically, the design DB2570 stores information on suitable organisms according to climate type, vegetation, geographical characteristics, chemical properties of soil, and the like. For the combination of suitable organisms automatically selected from the input initial information or the combination of organisms specified in advance by the client, the Design Department 2110 totals the economic values of those organisms to the target site. Calculate the economic value that would occur if a target ecosystem that could be reconstructed settled in the target area. In this specification, "calculation" or "calculation" performed by the AP server 2100 including the design unit 2110 means to output a calculated estimated value or an approximate value, and an actually measured value describing the actual situation is used. It is not to calculate.

When the target ecosystem is determined through such an ecosystem redesign process S2, the design unit 2110 holds the determined target ecosystem information in the storage unit 2500 in association with the information for identifying the target site. Let (S3). In particular, the value information DB 2530 stores at least the future economic value (target value) obtained by reconstructing the target ecosystem. In addition, it is preferable to store the ecosystem state information of the target ecosystem in the ecosystem information DB 2550. Ecosystem state information of the target ecosystem includes symbols such as names or IDs for uniquely identifying the target ecosystem type, and one or more organisms selected to compose the target ecosystem. Biological and functional characteristics and biological role in target ecosystems can be illustrated. Ecosystem types include "forest", "satochi satoyama", "grassland", and "marsh", but these are subconceptualized by vegetation type to give names and symbols that can uniquely identify ecosystems with different vegetation types. It is preferable to use it (see FIG. 5). Names that uniquely identify the ecosystem type of the forest ecosystem include, for example, "secondary Quercus crispula forest", "natural oak forest", and "secondary oak forest" that uniquely identify the forest ecosystem type by the dominant tree species. Can be mentioned.

Information processing in the ecosystem redesign stage is composed of the above-mentioned information processing of S1 to S3. The next stage of ecosystem redesign is information processing (transitional information processing S4) in the process of reconstructing the redesigned ecosystem in the target area.

The process of reconstructing the designed ecosystem is the process of establishing the organisms that make up the target ecosystem in the target area and guiding the target ecosystem. In this process, an ecological survey of the target area is performed, and progress information processing S4 is performed based on the information (ecosystem state information) obtained by the survey.

In the transitional information processing S4, at each of the time points of the plurality of ecological surveys, the ecosystem state information of the current ecosystem is acquired, and the value calculation unit 2150 is based on the acquired ecosystem state information to make the economic of the current ecosystem. Calculate the value (current value). The calculated present value is held in the value information DB 2530.

<Initial information input processing>
The information processing in each step will be described in detail below. In the initial information input process S1, the attribute information of the land to be the target of the ecosystem redesign and the economic value before the ecosystem redesign are input and stored in the DB server 2500. In addition, it is preferable to acquire the ecosystem state information of the target site before the ecosystem redesign and store it in the DB server 2500.

FIG. 3 shows an example of an input screen for inputting information in the initial information input process S1. The client uses, for example, the device 20 to display the input screen shown in FIG. 3 on the display unit, and inputs the attribute information of the target area for which the ecosystem is to be redesigned. The portion (3-A) surrounded by the solid line in FIG. 3 is the record held by the land information DB 2510, and the portion 3-B surrounded by the broken line is the record held by the ecosystem information DB 2550.

As the attribute information of the target area, it is preferable to input the location information of the unit (generally the town level) at which the climate of the target area can be grasped and store it in the land information DB 2510. Further, as attribute information other than the location, it is preferable to store the lot number, land area (area), type, right holder, and right content according to the registration information.

FIG. 4 shows an example of a land information table held by the land information DB 2510. In the example shown in FIG. 4, land IDs are distributed in units (generally at the town level) where the climate of the target area can be grasped as a primary key for uniquely identifying the target area. That is, among the land IDs in the leftmost column, OSKKA-A is the location code, the first two-digit symbol OS indicates the prefecture, the next two-digit symbol KA is the municipality, and the one-digit symbol A after the hyphen is the town. Indicates the location of the level.

The required input information in the initial information input step S1 is the location of the target site and the economic value (initial value) in the initial state before the ecosystem is redesigned. The initial value may be the registered value of the target area or the value based on the actual condition of the target area. In the former case, the land price, which is the basis of the fixed asset calculation, may be entered as the initial value, and in the latter case, the land price calculated when buying or selling the target land may be entered.

The above information can be acquired and input without conducting an ecological survey of the target area. The initial information input step S1 includes a step of inputting information that can be input without an ecological survey (attribute information input step) and a step of inputting information obtained by the ecological survey (ecosystem state information input step). Is preferably included.

Information obtained from ecological surveys includes information on the physicochemical and biological conditions of the target area. Information on the physicochemical situation includes meteorological information (information on temperature, precipitation and sunshine) that affects the temperature and moisture conditions of the target area, and information indicating the physicochemical state of the target soil (soil physicochemical). Information). Meteorological information can be acquired and input from various publicly known meteorological information databases. Soil physicochemical information can be obtained and input by known soil diagnosis. Soil physicochemical information includes pH, electrical conductivity (EC), ammonia nitrogen concentration, nitrate nitrogen concentration, organic phosphoric acid concentration, exchangeable potassium concentration, phosphoric acid absorption coefficient, exchangeable lime concentration, and exchangeability. There are soil concentration, exchangeable manganese concentration, available iron concentration, available copper concentration, available zinc concentration, boron concentration, cation exchange capacity (CEC), rot plant content, soil property and the like.

Information on the biological situation includes terrestrial zoological information and underground zoological information. As the terrestrial organism information, identification information (for example, a name) that uniquely identifies each of the main plants, animals, and other organisms constituting the terrestrial ecosystem and the abundance of each are acquired and stored in the ecosystem information DB 2550. It is preferable to hold it. The abundance may be an estimated value based on a survey or an estimated value obtained by calculation (the same applies hereinafter). Examples of "main plants and animals constituting the terrestrial ecosystem" include plants and animals that characterize the ecosystem, and plants and animals (selected organisms) selected as organisms that constitute the target ecosystem. Organisms that characterize an ecosystem include organisms that dominate an ecosystem (dominant organisms) and plants and animals that have a certain amount or more (representative organisms). Examples of other organisms include microorganisms that coexist with plants, animals, and the like (including parasitism, mutualism, and opportunistic infections). In the initial information input step S1, since the selected organism has not been determined, information on the representative organism or the dominant organism is acquired. The identification information that uniquely identifies an organism may be a symbol or the like in addition to a name, and the classification hierarchy may be specified by any hierarchy selected as necessary, such as a family, a genus, a species, a subspecies, or a lineage.

The AP server 2100 of the management system 1 is provided with a value calculation unit 2150. The value calculation unit 2150 refers to a database (design DB2570 in this embodiment) in which the economic value of each organism constituting the ecosystem is recorded, and refers to the economics of the current ecosystem (initial ecosystem) of the target site. Calculate the value based on the initial information entered. In this embodiment, the design DB 2570 shown in FIG. 6 records the economic value, suitable climate and ecosystem type for each organism. The value calculation unit 2150 refers to the value information DB 2530 and the design DB 2570 based on the respective names of a plurality of organisms constituting the initial ecosystem input as the terrestrial zoology information, and determines the abundance and value (unit price). Multiply to calculate the economic value of each organism. The value calculation unit 2150 also adds up the economic values calculated for each organism and calculates the economic value of the initial ecosystem (initial ecosystem value) in the target area.

The subterranean flora includes soil animals of visually identifiable sizes, such as beetles and worms, as well as fungi (synonymous with filamentous fungi or fungi in this specification), bacteria, actinomycetes, and algae and nematodes. Includes micro-organisms called protozoa-like subterranean microbes (microorganisms contained in soil microflora and symbiotic microbes in subplants of plants). As the underground biological flora information, it is preferable to acquire information on underground microorganisms among the organisms contained in these underground biological flora and store it in the DB server 2500 (ecosystem information DB2550). Information on underground microorganisms includes the number of animals per unit volume (or weight) of soil and plant roots, and the number of cells of fungi, bacteria and actinomycetes (or estimated values based on colony-forming units and DNA content). Also, there is the diversity (α-diversity, β-diversity, γ-diversity) of these species of organisms and other taxonomic hierarchies (can be substituted by operational taxonomic units and amplicon sequencing variants). In addition, regarding microorganisms (core microorganisms) that are useful for constructing a target ecosystem, which are identified by the microbial flora design described later, identification information (names, etc.) that can identify the microorganisms and notable functional features (for plant A) It is preferable to keep it in the DB server 2500 (ecosystem information DB2550) together with growth promotion, suppression of feeding damage by insect B, etc.).

<Ecosystem redesign process>
Next, the ecosystem redesign process S2 will be described. FIG. 5 shows an example of a screen displayed on the device 20 when the client redesigns the ecosystem. The client uses the device 20 to display the design screen shown in FIG. 5 on the display unit, and inputs the design goal. The design objective should be information about the ecosystem to be redesigned (at least one of the type and constituent species) or at least one of the economic values obtained by reconstructing the target ecosystem. In this embodiment, both the target ecosystem and the economic value are set as design targets, and for the ecosystem, the use, the type of the ecosystem, and the species constituting the ecosystem can be specified.

Upon receiving the input of the ecosystem design target from the device 20, the design unit 2150 extracts the items (design information) for redesigning the ecosystem from the input values input as the design target, and for designing. With reference to DB2570, a combination of suitable organisms (ecosystem redesign model) that matches the extracted items is selected. The design information extracted by the Design Department 2110 for ecosystem redesign is preferably information that specifies the climate type, ecosystem type, and functional characteristics of the organisms that make up the ecosystem. In the example shown in FIG. 5, the climate type of the target area is specified by using a known database based on the location information of the target area. The design unit 2110 creates a combination of organisms that match the conditions from the design DB 2570 on the condition of this climate type information and the ecosystem type and constituent organism information specified by the client. Then, the economic value of the combination of organisms created by the value calculation unit 2150 is calculated, and the combination of organisms that meet the target economic value condition specified by the client and the economic value due to them are output as a design proposal of the ecosystem redesign model. And display it on the device 20.

<Goal setting process>
The client refers to the design proposal output by the ecosystem redesign process, specifies the organisms that make up the target ecosystem, and determines the composition of the target ecosystem. In this step (target setting process S3), the management system 1 creates information about the target ecosystem in the following flow, and stores the information in the storage unit 2500.

When the business server 10 receives the determination of the target ecosystem from the client, the value calculation unit 2150 adds up the economic values of the organisms constituting the determined target ecosystem, and the target ecosystem is reconstructed in the target area. Calculate the economic value (target value) obtained by. The target value can be calculated by multiplying the target abundance in the target ecosystem and its unit value for each organism that constitutes the target ecosystem, and adding them up.

The design unit 2110 of the management system 1 related to this embodiment has a function of identifying microorganisms useful for guiding the target ecosystem based on the initial microbial flora information. Specifically, in the initial information input process S1, one of the soils of the target area or the plants growing in the target area, preferably both, is used as an analysis sample, and biological information of the microbial ecosystem contained in the sample is acquired. , It is retained in the ecosystem information DB 2550. Then, once the organisms constituting the target ecosystem are determined, it is known that the potential function of the microorganism is estimated from the biological information of the microbial flora held in the ecosystem information DB 2550 and the gene sequence information derived from each microorganism. Annotation tools are used to identify microorganisms (core microorganisms) that contribute to the colonization and / or growth of the organisms that make up the target ecosystem. As a method for identifying a core microorganism, there is a method described in Japanese Patent Application No. 2020-039972. The Design Department 2110 uses a known microbial database in which the gene sequence information of various microorganisms and the potential functions of the microorganisms are recorded from the gene sequence information according to the method described in Japanese Patent Application No. 2020-039972. To identify core microorganisms. The term "specification" as used herein means to find a microorganism presumed to be a core microorganism by an arithmetic process for estimating a microorganism capable of functioning as a core microorganism based on the gene sequence information of the microorganism. The identified core microorganisms improve the survival rate and growth of the selected organisms by inoculating the organisms (selected organisms) that construct the target ecosystem, and facilitate the induction of the target ecosystem.

The target value calculated by the value calculation unit 2150 is held in the value information DB 2150. In addition, other information about the target ecosystem, which is used for calculating the value of the target ecosystem, specifically, information on the organisms constituting the target ecosystem is also retained in the value information DB 2150 or in the ecosystem information DB 2550. It is preferable to link it to the provided information. Information on the organisms that make up the target ecosystem preferably includes identification codes such as names that uniquely identify the organisms that identify them, and the target abundance of each of them. Further, information about core microorganisms (for example, functional features) may be stored in the DB server 2500. The storage medium for storing information about the ecosystem other than the information about the value of the ecosystem is not particularly limited.

FIG. 7 shows an example of the information held by the value information DB 2150. The part shown by the solid line 7-A is the information input and held (in the initial information input process S1 and the target setting process S3) before the construction of the target ecosystem is started. The part indicated by the broken line 7-B is the information input and held (in the progress information processing S4) after the construction of the target ecosystem is started.

<Progress information processing>
Progressive information processing S4 is performed at a plurality of time points in the process of reconstructing the target ecosystem. The transitional information processing S4 processes information indicating the state of the ecosystem (current ecosystem) that has been redesigned in the target area and is in the process of reconstruction. Therefore, in the transitional information processing S4, prior to the information processing, an ecological survey in the target area is performed, and the information of the current ecosystem acquired based on the survey is used as an input value. Ecological surveys at the target site are conducted at intervals set as a period suitable for grasping the induction state of the target ecosystem (for example, every few months for forests, every few weeks for fields, etc.). ..

In ecological surveys at multiple time points, it is preferable to obtain soil physicochemical information and information on biological conditions (particularly information on biological conditions at the time of each survey of terrestrial and underground microbial flora). The weather information may be acquired at any time using various sensors or the like, or the information obtained from a known weather information service may be retained in the ecosystem information DB 2550 in accordance with the progress information processing S4.

Underground microbial flora information confirms whether a soil microbial flora suitable for inducing the target ecosystem is constructed, assists in promoting the growth of selected organisms, and adds microorganisms to protect from the effects of pests. It can be used for inoculation.

As the terrestrial bioplasm information, the abundance of one or more selected organisms in the current ecosystem is used as the input value in the transitional information processing S4. The value calculation unit 2150 refers to any one or more of the value information DB 2530, the ecosystem information DB 2550, and the design DB 2570 as necessary, and considers the present value of the selected organism in the current ecosystem and its economic value. Calculate the present value of the system. The existing amount may also be an estimated value based on calculation or survey (the same applies hereinafter). In this embodiment, the organisms selected for the redesign of the ecosystem are subjected to multiple ecological surveys before monetization, and the role of the selected organisms assumed in the target ecosystem is the current ecology of the selected organisms. Evaluate how much the role is achieved (completeness of selected organisms) from information such as the abundance in the system. Then, the value calculation unit 2150 calculates the economic value of the selected organism in consideration of the degree of perfection in the current ecosystem. In the example of Fig. 7, for the selected organisms (sugi) that need to be subjected to ecological surveys three times a year for 30 years before monetization, the existing amount is calculated and the growth amount of the selected organisms in each survey. The economic value is calculated by correcting it by (1/3 times x 30 years).

When there are multiple selected organisms, the value calculation unit 2150 uses the existing amount of each selected organism in the current ecosystem as an input value, refers to the economic value of each selected organism from the design DB 2570, and makes the above corrections as necessary. And calculate the economic value of each selected organism. Next, the value calculation unit 2150 calculates the value (present value) of the current ecosystem by adding up the economic values of each selected organism. If there are organisms with economic value other than the selected organisms (non-selected organisms) in the current ecosystem, the non-selected organisms are added to the constituent organisms, and the value calculation unit 2150 also has an economic value based on the abundance of the non-selected organisms. It may be configured to add up and calculate the present value. The present value calculated by the value calculation unit 2150 is held in the value information DB 2530.

It is preferable that the value calculation unit 2530 is further designed to output information on the completeness of the ecosystem. Specifically, the difference between the number and abundance of each selected organism in the target ecosystem and the number and abundance of each selected organism in the current ecosystem is calculated to complete the target ecosystem of the current ecosystem. Calculate the degree. Information on the degree of perfection of the current ecosystem may be retained in the ecosystem information DB 2550, but in this embodiment, it is retained in the value information DB 2530.

When a plurality of present values are held together with time-series information in the value information DB 2530, the value calculation unit 2150 of the present embodiment reconstructs the present value and the time-series information from the plurality of present values and the time-series information at a specified time in the future. It may have the function of predicting the value of an ecosystem that has been (or is in the process of being reconstructed) as a future value. In the value calculation unit 2150, arbitrary statistical modeling is applied to estimate the future value from, for example, a plurality of present values and their time series information (measurement date and measurement interval). In statistical modeling that predicts the future value of the current ecosystem, the prediction accuracy is improved by referring to the information on the degree of perfection of the current ecosystem for the target ecosystem at a certain point in time.

<Information management of adjacent target areas>
In the land information DB 2510 of FIG. 4, a plurality of target sites having different right holders and adjacent target sites (land IDs OIUS-N-5678 and OIUS-N-5679) are grouped together to redesign the ecosystem. It is one target (adjacent target area) to perform. Regarding the adjacent target area, in the initial information input process S1, the attribute information (ID identified as the same adjacent target area, the area as the adjacent target area, all right holders) is used for the plurality of target areas constituting the adjacent target area. Is held in the land information DB 2510. Then, in the redesign of the ecosystem, the target ecosystem is redesigned with the adjacent target area having the same ID as the minimum unit. Then, the initial value, present value, future value, and target value are calculated for each adjacent target area and stored in the value information DB 2530.

The right holder management department 2170 requests the calculation of the present value of the target site designated by the client among the target sites constituting the adjacent target site in the designated target area of the ecosystem reconstructed in the adjacent target area. accept. In that case, the right holder management department 2170 refers to the land information DB 2510, divides the present value of the adjacent target area by the area ratio occupied by the designated target area, and calculates the present value of the current ecosystem in the designated target area. .. In this way, by managing multiple target sites that are adjacent to each other and have different rights holders as adjacent target sites, it is possible to redesign and reconstruct the ecosystem beyond the artificially set registration boundaries. At the same time, the economic value obtained from the redesigned and reconstructed ecosystem can be distributed to the right holders of the target land that constitutes the adjacent target land.

In this management system 1, a database (land information DB, value information DB, ecosystem information DB, design DB) for each type of information is provided in the DB server 2500. However, the database is not limited to the business server group 10 alone, and may be provided in another external server, and the configuration of each database is not limited to the one illustrated in this embodiment.

<Ecosystem guidance method>
Another aspect of the invention relates to a method of inducing a redesigned ecosystem with backcast thinking. As one embodiment of the ecosystem induction method according to the present invention, a land having a low economic value such as an abandoned cultivated land is targeted, and the economic value at that time is grasped and an ecological survey is conducted. .. Then, based on the obtained ecological survey results, information on the existing microbial flora that inhabits the land to be surveyed is preferably obtained.

In addition, based on the physicochemical conditions of the land (climate, soil condition, topography, etc.), it is easy to grow in the land, and agricultural and forestry products suitable for trading in the market are identified, and maintenance costs are suppressed. Redesign ecosystems containing organisms that are easy to harvest agricultural and forest products. Then, the allowance to identify the core microorganisms that are beneficial for inducing the redesigned ecosystem, and to build a symbiotic relationship between the core plants (selected plants) and the core microorganisms that are the key to inducing the redesigned ecosystem (hereinafter, It is advisable to carry out "symbiotic system induction treatment") and start the induction of the redesigned ecosystem.

As the symbiotic induction treatment, seedlings obtained by inoculating the seeds of the selected plant with core microorganisms to germinate and raising seedlings, or growing the seeds and seedlings of the selected plants with the soil inoculated with the core microorganisms are targeted. There are methods such as planting in the soil and mixing materials such as soil containing core microorganisms with the soil in which the selected plants are growing. Non-Patent Document 1 describes that a symbiotic relationship between a selected plant and a core microorganism can be artificially induced by identifying a core microorganism and performing a symbiosis induction treatment.

The ecosystem induction method according to the present invention induces an ecosystem redesigned by backcast thinking by using the identification of core microorganisms and the symbiotic system induction treatment using core microorganisms disclosed in Non-Patent Document 1. do. In the present invention, even after the induction of the redesigned ecosystem is started, the ecological survey of the target area is carried out as appropriate, and the symbiotic system induction treatment is performed as necessary.

In this way, information on the ecological state of the ecosystem in the process of inducing the redesigned ecosystem from the redesign of the ecosystem is obtained, and the economics of the ecosystem being constructed at that time are obtained. Improve the economic value of the land in the target area by calculating the value.

The land value information management system according to the present invention induces an ecosystem designed by backcast thinking as an ecosystem having a desired economic value with respect to an ecosystem constructed in a natural environment, and the land economy. It can be used to improve the target value. According to the present invention, agricultural products and fruits traded in the agricultural crop market, etc., targeting land that is not used for economic activities and has a low substantial economic value, such as abandoned forests and degraded agricultural land. Ecosystems suitable for harvesting, such as timber and wild grass, can be redesigned to induce designed satoyama and complex agricultural forests.
