{Evaluation system for risk management of invasive alien species}

The present invention relates to an invasive alien species risk management evaluation system and an evaluation method using the same. More specifically, the present invention relates to a theoretical and empirical synthesis of information on the dynamics of invasive alien species and the risk that invasive alien species pose to the ecosystem through this information. An invasive alien species risk management evaluation system to objectively evaluate the comprehensive risk that invasive alien species affect the ecosystem and society by applying human management and evaluation for ecosystem conservation from invasive species to the ecological model and implementing a virtual model. This is about an evaluation method using this.

Recently, climate change, invasion of alien species, and disturbed biodiversity conservation systems have been presented as key threats to maintaining the stable sustainability of the ecosystem. In particular, as human and material exchanges between countries have expanded due to globalization and increased trade activities, the Damage to ecological stability and economic losses due to inflow are intensifying around the world.

The International Union for Conservation of Nature (IUCN) reported that economic losses resulting from the destruction of natural ecosystems by invasive alien species amount to hundreds of billions of dollars worldwide every year, and listed the world's top 100 invasive alien species to indicate the severity of their impact.

In Korea, invasive alien species such as nutria, red-eared turtles, bluegill, and bass imported for farming or eating are disturbing and destroying our country's natural ecosystem. Recently, due to the increase in the pet population, various types of exotic pets have been introduced. The risk of ecosystem disturbance is further increasing through the introduction of these exotic pets into the ecosystem.

As such, the threat to the ecosystem caused by invasive alien species is increasing in Korea, but the management system for this is inadequate, and there is a lack of empirical research on invasive alien species, making it difficult to respond to invasive alien species.

In addition, the analysis and modeling of ecological data in research on invasive alien species has fundamental limitations. Specifically, ecological ideas are difficult to objectively analyze and predict because many factors, both living and non-living, are complexly involved, and data are insufficient. , it is difficult to conduct experiments directly because it involves problems such as disease spread.

Therefore, objective monitoring or management measures are needed through maximum information collection and efficient modeling. In particular, the objectivity of the risk management and evaluation system for invasive alien species is involved in policies such as control and blocking of invasive alien species, so the development of a reliable evaluation system is necessary. This is the situation.

The invasive alien species risk management evaluation system (hereinafter referred to as the 'invasive alien species evaluation system') according to an embodiment of the present invention will be described below based on (a) and (b) of Figures 1 to 4 attached. do.

Figure 1 is a diagram showing the configuration of an invasive alien species risk management evaluation system according to an embodiment of the present invention, and Figure 2 is an exemplary diagram showing integrated ecological information generated in the environmental comprehensive unit 20 of Figure 1 as a graph, Figure 3 is an example diagram showing graphically the ecological evaluation information generated in the environmental comprehensive department 20 of Figure 1, and Figures 4 (a) and (b) are examples showing survey information generated by the survey design department of Figure 1. It is also a degree.

The invasive alien species evaluation system (1) according to an embodiment of the present invention is an evaluation system for evaluating the comprehensive risk that invasive alien species affect the ecosystem and society by designing questionnaire items and applying an ecological model.

Here, invasive alien species is a general term for introduced species, naturalized species, and invasive species, and refers to species that come from outside the original native habitat and reproduce by occupying the habitat of other organisms, regardless of whether there is a specific artificial purpose.

Examples of these invasive alien species include nutria, red-eared slider, bluegill, bass, ragweed, spiny gourd, and rattlesnake.

Below, an example of nutria among invasive alien species is presented to help understand the present invention. However, invasive alien species can be selected in various ways and results may vary depending on the selected invasive alien species, and the scope of rights of the present invention is as follows. It is not limited.

Referring to Figure 1, the invasive alien species evaluation system (1) includes a dynamic synthesis department (10), an environmental synthesis department (20), a survey design department (30), a model implementation department (40), and a comprehensive evaluation department (50). You can.

First, the dynamic synthesis unit 10 can generate dynamic information by synthesizing the mechanistic factors for the dynamics of the invasive alien species and the experiential factors corresponding to the mechanistic factors.

Here, dynamic means that organisms move, give birth, adapt to the environment, and spread spatially over time.

Additionally, mechanistic factors refer to factors that are causally caused in a process based on natural principles or rules for the dynamics of invasive alien species.

These mechanistic factors can be obtained based on ecological data on the dynamics of existing invasive alien species.

Additionally, examples of mechanistic factors include non-directional movement, reproduction, group formation pattern, temperature, habitat, and food.

Additionally, experience factors can be obtained based on papers, literature, and experimental results related to invasive alien species.

Specifically, the dynamic synthesis unit 10 can divide the mechanism factors into intrinsic mechanism factors and extrinsic mechanism factors and generate dynamic information by synthesizing the experience factors for each mechanism factor.

Here, intrinsic mechanistic factors are mechanistic factors that arise from the invasive alien species itself, and extrinsic mechanistic factors are factors that arise from relationships with external factors such as the environment, people, and ecosystem.

Examples of intrinsic mechanisms include non-directional movement, reproduction, and group formation, while examples of extrinsic mechanisms include temperature, habitat, and food.

Accordingly, the dynamic synthesis unit 10 can generate more systematic dynamic information by dividing the mechanistic factors into intrinsic mechanistic factors and extrinsic mechanistic factors and synthesizing the experiential factors.

Additionally, the user can determine how the experience factors correspond to the mechanism factors through the dynamic information generated by the dynamic synthesis unit 10.

To summarize the process by which the dynamic synthesis unit 10 generates dynamic information, first, the mechanism factors are classified based on ecological data, and each mechanism factor can be classified into intrinsic mechanism factors and extrinsic mechanism factors.

Specifically, for example, the dynamic synthesis unit 10 classifies non-directional movement, reproduction, group formation form, temperature, habitat, food, etc. as mechanism factors, and among these, non-directional movement, reproduction, group formation form, etc. As mechanistic factors, temperature, habitat, food, etc. can be classified as extrinsic mechanistic factors.

Thereafter, the dynamic synthesis unit 10 can generate dynamic information by classifying and synthesizing the experience factors corresponding to each mechanism factor.

Specifically, for example, the dynamic synthesis unit 10 can derive herd life, which is a form of group formation of nutria in an actual ecosystem, as an experience factor in response to group formation among the mechanism factors.

As another example, non-seasonal reproduction can be derived as an experience factor in response to the reproduction of nutria in the actual ecosystem from reproduction among the mechanistic factors.

Next, the environmental synthesis department 20 can generate integrated ecological information by deriving integrated ecological elements based on the dynamic information, and generate ecological evaluation information by deriving ecological evaluation elements based on the integrated ecological information.

Specifically, the environmental synthesis department 20 can derive integrated ecological factors based on mechanism factors and experience factors with similar characteristics among the mechanism factors and experience factors of dynamic information.

Here, integrated ecological factors may include risk factors, which are the negative impacts of invasive alien species on the ecosystem and society, and management factors, which are measures taken to prevent the spread of invasive alien species.

In addition, the Environmental Comprehensive Department (20) classifies hazards and management factors into one or more major categories, classifies the major categories into subcategories, assigns weights to the major categories and minor categories, and synthesizes each weight to generate integrated ecological information. You can.

Afterwards, the Environmental Comprehensive Department 20 can assign weights to major and subcategories using the Delphi method, which synthesizes multiple opinions.

At this time, when assigning a weight to a subcategory, the weight may be assigned based on the experienced factors of the mechanism factors included in the subcategory, that is, the hazard.

Accordingly, the environmental synthesis unit 20 can generate objective integrated ecological information.

Additionally, the environmental synthesis unit 20 can calculate the integrated ecological element importance by multiplying the weight of each subcategory and the weight of the major category to which each subcategory belongs.

Accordingly, the environmental synthesis department 20 can present the importance of each integrated ecological element of integrated ecological information, that is, the importance of hazard elements and the importance of management elements.

In addition, the Environmental Comprehensive Department (20) can derive ecological evaluation factors based on integrated ecological factors with similar characteristics among the integrated ecological factors of integrated ecological information.

In addition, the environmental synthesis unit 20 may classify ecological evaluation elements into one or more major categories, classify the major categories into subcategories, assign weights to the major categories and minor categories, and synthesize the respective weights to generate ecological evaluation information.

Afterwards, the Environmental Comprehensive Department 20 can assign weights to major and subcategories using the Delphi method, which synthesizes multiple opinions.

At this time, when assigning weights to subcategories, weights may be assigned based on integrated ecological factors included in the subcategories, that is, ecological evaluation factors.

Accordingly, the environmental comprehensive department 20 can generate objective ecological evaluation information.

Additionally, the environmental synthesis unit 20 can calculate the importance of ecological evaluation information by multiplying the weight of each subcategory and the weight of the major category to which each subcategory belongs.

Accordingly, the environmental synthesis department 20 can present the importance of each ecological evaluation element of the ecological evaluation information.

For an example of the process of generating integrated ecological information by the Environmental Comprehensive Department (20), referring to Tables 1 and 2 above, Tables 1 and 2 provide integrated ecological information on nutria, one of the invasive alien species, to the Environmental Comprehensive Department (20). This is a table created from .

Specifically, Table 1 is a table showing the classification of risk factors for nutria, and Table 2 is a table showing the classification of management factors.

As described above, the environmental synthesis department 20 can derive integrated ecological factors based on dynamic information and classify the derived integrated ecological factors into hazard factors and management factors.

Specifically, the Environmental Comprehensive Department 20 can derive reproductive power among hazardous factors based on the number of breeding individuals with similar characteristics, reproduction, breeding frequency, etc. among dynamic information.

As another example, habitat adaptability among risk factors can be derived in response to ideas based on the common basis of carrying limit, habitat adaptation, island susceptibility hypothesis, and natural environment adaptation.

Thereafter, the environmental comprehensive department 20 classifies the hazards derived in the same manner as above into major categories, subdivides the major categories, and classifies them into minor categories.

Specifically, the environmental comprehensive department 20 may classify hazards into major categories of organisms, environment, and humans, and among the major categories, the reproductive capacity associated with organisms may be classified into the subcategories of organisms.

As another example, among the major categories, habitat adaptability related to the environment can be classified into a subcategory of the environment.

Thereafter, the environmental synthesis unit 20 may classify weights into each major category and minor category.

Specifically, the Environmental Comprehensive Department 20 can assign scores to each major category of hazards, that is, 5 points for organisms, 3 points for the environment, and 2 points for humans, etc., using the Delphi method that synthesizes multiple opinions.

In addition, the Environmental Comprehensive Department 20 can assign scores to each subcategory of hazards, that is, 5 points for reproductive ability, 4 points for habitat adaptability, and 4 points for capture inefficiency, etc., using the Delphi method that synthesizes multiple opinions.

At this time, when assigning a weight to a subcategory, the main subcategory is judged based on the experienced factors of the mechanism factors included in the subcategory, that is, the hazard, and if it is determined to be a major subcategory, a higher weight may be assigned.

Thereafter, the environmental synthesis unit 20 can present the integrated ecological element importance by multiplying the weight of each subcategory and the weight of the major category to which each subcategory belongs.

Specifically, in the case of fertility, it is a subcategory of a major category of organisms and can have a hazard importance level of 25 points by multiplying 5 points, the weight of the organism, and 5 points, the weight of fertility.

Another example is that in the case of habitat adaptability, a hazard importance level of 12 points can be obtained by multiplying the environmental weight of 3 points, which is a subcategory of the major environment, by the weight of habitat adaptability, which is 4 points.

All information such as major categories, subcategories, weights, and importance of integrated ecological elements generated in the above process can be included in integrated ecological information.

Additionally, management factors can generate integrated ecological information using substantially the same method as hazard factors.

Additionally, as shown in Figures 2 and 3, integrated ecological information can be converted into a graph form so that users can distinguish the importance of integrated ecological elements at a glance.

Referring to Table 3 above, as an example of the process in which the Environmental Comprehensive Department (20) generates ecological evaluation information, Table 3 is a table generated by the Environmental Comprehensive Department (20) of ecological evaluation information for nutria, one of the invasive alien species.

Specifically, Table 3 is a table showing the classification of ecological evaluation elements for nutria.

As described above, the environmental synthesis department 20 can derive ecological evaluation factors based on integrated ecological information.

Specifically, the Environmental Comprehensive Department (20) can derive abnormal proliferation among ecological evaluation factors based on the number of breeding individuals with similar characteristics, habitat adaptability, and indirect dispersal among integrated ecological factors.

Thereafter, the environmental synthesis department 20 classifies the ecological evaluation factors derived in the same manner as above into major categories, subdivides the major categories, and classifies them into minor categories.

Specifically, the Environmental Comprehensive Department 20 classifies ecological evaluation factors into the major categories of stability, safety, and social impact, and, for example, among the major categories, abnormal growth related to stability may be classified into the subcategory of stability.

Thereafter, the environmental synthesis unit 20 may classify weights into each major category and minor category.

Specifically, the Environmental Comprehensive Department (20) can assign scores to each major category of ecological evaluation factors, that is, 5 points for stability, 2 points for safety, and 3 points for social impact, using the Delphi method that synthesizes multiple opinions. .

In addition, the Environmental Comprehensive Department (20) can assign scores to each subcategory of ecological evaluation factors, that is, 3 points for abnormal growth, 5 points for infectious diseases, 3 points for social impact, etc., using the Delphi method that synthesizes multiple opinions. .

At this time, when assigning a weight to a subcategory, the main subcategory is judged based on the importance of the integrated ecological elements included in the subcategory, that is, the ecological evaluation factors, and if it is determined to be a major subcategory, a higher weight may be assigned.

Thereafter, the environmental synthesis unit 20 can present the importance of ecological evaluation factors by multiplying the weight of each subcategory by the weight of the major category to which each subcategory belongs.

Specifically, in the case of abnormal proliferation, it is a subcategory of stability, which is a major category, and can have an ecological evaluation factor importance of 15 points by multiplying the weight of stability, which is 5 points, and the weight of abnormal growth, which is 3 points.

All information such as major categories, subcategories, weights, and importance of ecological evaluation elements generated in the above process can be included in ecological evaluation information.

Next, the survey design unit 30 may generate survey information including one or more survey items designed based on dynamic information, integrated ecological information, and ecological evaluation information.

Specifically, as shown in (a) and (b) of FIG. 4, the survey design unit 30 derives one or more major classifications by considering dynamic information, integrated ecological information, and ecological evaluation information by a number of experts, and each Survey information can be generated by designing one or more survey items for a major category into subcategories.

Additionally, an interval scale can be provided for each survey item.

For example, each survey item may be provided on a scale of 0 points (unnecessary) to 5 points, but is not limited to this and may be provided in a variety of ranges.

Afterwards, the survey information generated by the survey design unit 30 can be provided to multiple experts, and the survey results can be saved again as survey information.

Accordingly, the survey design unit 30 can numerically measure the opinions of a number of experts on the subject, concept, phenomenon, etc. of the invasive alien species of the surveyor through the equal interval scale.

Next, the model implementation unit 40 can generate a virtual model by applying dynamic information, integrated ecological information, ecological evaluation information, and background information related to existing invasive alien species to the ecological model.

Here, the background information may be data on the dynamics of existing invasive alien species used when extracting mechanistic factors.

In addition, the ecological model may include a data-based model that evaluates the risk to invasive alien species through input information and a mechanism model that evaluates the risk to invasive alien species based on physical laws or natural rules.

Specifically, examples of data-based models include Maxent model and Bayesian model.

Additionally, the mechanism model may include an individual-based model (IBM).

In other words, the model implementation unit 40 divides independent variables and dependent variables according to the classification and purpose of management and evaluation for dynamic information, integrated ecological information, ecological evaluation information, and background information, and uses them as a data-based model and mechanism model. By inputting and outputting a virtual scenario, you can create a data-based virtual model and a mechanistic virtual model by simulating and predicting the virtual scenario.

For example, if the distribution of invasive alien species is the goal, a virtual model can be created by inputting the reporting density of hazardous elements as the dependent variable and temperature, food source, predators, etc. as the independent variables.

As another example, if economic damage from invasive alien species is the goal, a virtual model can be created by inputting economic damage from ecological evaluation factors as the dependent variable and control costs and economic losses as independent variables.

In addition, the model implementation unit 40 may generate a virtual model of either a data-based model or a mechanism model according to the user's selection, and may use both the data-based model and the mechanism model to create a data-based virtual model and a mechanism virtual model. You can also create

Additionally, the comprehensive evaluation unit 50 may generate comprehensive evaluation information by applying regular evaluation, which evaluates the virtual model according to a certain point in time, and dynamic evaluation, which evaluates each element according to one or more scenarios.

Here, each element means hazard element, management element, and ecological evaluation element.

Additionally, regular evaluation and dynamic evaluation may be performed separately or simultaneously.

Specifically, the comprehensive evaluation unit 50 receives a certain point in time from the user and evaluates the data-based virtual model and the mechanical virtual model at the input certain point in time to derive numerical information and generate comprehensive evaluation information.

In addition, the comprehensive evaluation unit 50 receives one or more parameters related to invasive alien species from the user and operates and evaluates a data-based virtual model and a mechanical virtual model based on the input parameters to derive numerical information and provide comprehensive evaluation information. can be created.

Here, the parameters may be reproductive capacity, habitat adaptation probability, core area area, etc.

Additionally, dependent variables can be dynamically presented in various ways depending on various conditions.

For example, in dynamic evaluation, parameters are set as reproductive capacity, habitat adaptation probability, core area area, unit area, and number of catches per hour.

Next, the virtual model can be operated by inputting the reproductive capacity of 3 animals, habitat adaptation probability of 0.5, core area width of 1 km, unit area, and number of catches per hour of 10 animals as parameters, and numerical information can be derived by repeating this a certain number of times. .

Through this, it is possible to determine the probability that invasive alien species can harm the ecosystem depending on the parameters.

In addition, the comprehensive evaluation unit 50 generates comprehensive evaluation information by combining the questionnaire information generated as above and the numerical information generated through the virtual model, and presents an evaluation grade through relative evaluation with other comprehensive evaluation information. can do.
