In the embodiment, a graphical analysis method is adopted to split the research flow into three steps of "S1 conflict object identification → S2 conflict intensity calculation → S3 conflict management prioritization", wherein the conflict object identification is to identify four conflict types: source-ground conflicts, corridor conflicts, safety conflicts and farmland conflicts; the calculation of the collision strength refers to the calculation of the collision strength of each collision type; the conflict treatment priority division refers to division of treatment priority according to the calculated conflict intensity and treatment level. And (3) carrying out graphic analysis in each step, wherein the graphic analysis comprises the technical processes of parameter determination, data sorting, simulation environment selection, modeling and the like.
Exemplary method
The embodiment provides a method for dividing governing priority of urban homeland space, which can be applied to intelligent terminals in the field of geographic information. As shown in fig. 1 in detail, the method includes:
s100, obtaining source images of a plurality of urban homeland spaces, and constructing an initial graphic model according to the source images;
specifically, the ecological protection red line is an area which has special important ecological functions and must be strictly protected forcibly in the ecological space range, and comprises an ecological source area, an ecological corridor and the like; the permanent basic farmland protection red line is a control line which is defined for guaranteeing the safety of grains and controls the disordered expansion of cities by rigid constraint. Ecological conservation red lines and permanent basic farmland conservation red lines are control boundary lines, stress protection control and limit construction behaviors. Illustration, a graphic thought derivation capability, is a thinking way and an explanation tool for showing the internal relationship of things through simple and easy-to-understand graphs. The urban case is subjected to formal logic analysis through graphical analysis, and the key point is to judge the spatial distribution, the expression form and the conflict degree of the potential conflict and set a differentiated treatment strategy according to the spatial distribution, the expression form and the conflict degree. In this embodiment, the source images of the plurality of urban territorial spaces include ecological protection red line images, permanent basic farmland protection red line images, town development boundary images and general ecological and agricultural space images, and the source images are planned in the urban territorial space planning. After source images of a plurality of urban homeland spaces are obtained, an initial graphic model can be constructed according to a plurality of source images. Correspondingly, in order to obtain the graphic model, the construction of the initial graphic model according to a plurality of the source images comprises the following steps:
s101, formatting a plurality of source images to obtain a plurality of formatted images;
and S102, overlapping a plurality of formatted images to obtain a graphical model.
Specifically, the data format processing is carried out on the images by using the ecological protection red line image and the permanent basic farmland protection red line image, so that the formats of all the images are unified, then the images can be unified in coordinates, and the ecological protection red line image and the permanent basic farmland protection red line image are spatially superposed to illustrate the model.
Having obtained the graphical model, the following steps can be performed as shown in FIG. 1: s200, obtaining a conflict object distinguishing graphical model based on the initial graphical model, and determining a space conflict intensity index corresponding to the conflict area according to the conflict object distinguishing graphical model; the conflict object distinguishing graphical model is used for analyzing the overlapping relation between the construction space and the spaces such as cultivated land and ecology in the urban homeland space.
In step S200, the obtaining of the collision object discrimination graphical model based on the initial graphical model includes the following steps: acquiring a current situation construction land area image and a potential safety hazard area image; obtaining a formatted intermediate area image according to the current construction land area image and the potential safety hazard area image; superimposing the formatted intermediate region image onto an initial graphical model; and identifying a conflict area in the initial graphical model by adopting a superposition analysis mode to obtain a conflict object discrimination graphical model.
Specifically, the town construction land within the town development boundary range is in line with the planning, but in practice, some current construction lands are illegal, and the illegal construction lands are distributed in the ecological protection red line area and the basic farmland protection red line area; in addition, in general ecological and agricultural spaces, there are potential safety hazard areas where current construction sites are distributed, such as high-voltage corridors, geological disaster prone areas, or safety protection ranges around large-scale sanitation facilities. Therefore, the areas to be paid attention to are both illegal construction land and potential safety hazard areas, and are collectively referred to as conflict land areas in the present invention. According to the current construction land area image and the potential safety hazard area image, a formatted middle area image is obtained, specifically, the current construction land area image and the potential safety hazard area image are formatted to obtain a formatted middle area image, namely the middle area image is possibly a collision land area image, the collision land area image comprises an illegal construction land area image and a potential safety hazard area image, and the formatted middle area image is superposed on an initial graphical model; as shown in fig. 2, a collision region in the initial graphical model is then identified by a superposition analysis method, so as to obtain a collision object discrimination graphical model. Specifically, when the current construction land area image is overlapped with the planned construction land, the illegal construction land is not available; when the current construction land area image is overlapped with an ecological source land in the ecological land, the overlapped area is a source land conflict area image, wherein the ecological source land is an ecological land which has a certain scale and is distributed in a concentrated manner in space; when the current construction land area image is overlapped with the ecological corridor in the ecological land, the overlapped area is the corridor conflict area image; when the current construction land area image is overlapped with the basic farmland protection area, the overlapped area is the cultivated land conflict area image, and when the current construction land area image and the potential safety hazard area image are overlapped with the general ecological and agricultural space, the overlapped area is the safety conflict area image. Therefore, four conflict areas can be obtained through the source conflict area image, the corridor conflict area image, the farmland conflict area image and the safety conflict area image: a source ground conflict area, a corridor conflict area, a farmland conflict area and a safety conflict area, wherein the four conflict areas are defined as follows.
After a conflict area is obtained, determining a spatial conflict intensity index corresponding to the conflict area according to the conflict area; the conflict area is used for representing the overlapping relation between the construction space in the urban homeland space and the spaces such as the cultivated land, the ecology and the like. Correspondingly, a plurality of conflict areas are provided; the step of determining the spatial conflict intensity index corresponding to the conflict area according to the conflict area comprises the following steps: analyzing the type of the conflict area; calculating the conflict index of each type of conflict area; wherein the conflict index is used for representing the conflict strength of the conflict area; accumulating conflict indexes of all types to obtain a space conflict intensity index corresponding to the conflict area; and forming a space conflict intensity index by the conflict index and the comprehensive conflict index.
Specifically, the type of the conflict area is analyzed, and in this embodiment, as shown in fig. 3, the type of the conflict area is four types, namely, active ground conflict, corridor conflict, safety conflict, farmland conflict, and the like. Then calculating the conflict index of each type of conflict area; wherein the conflict index is used for characterizing the conflict strength of a conflict area; in this example, the spatial impact strength Index (Conflict Index, CI) is used to reflect the degree of uncontrollable negative spatial type transformation and the intensity of spatial impact mutation over time. The invention is characterized by using a subentry conflict index (k) and a comprehensive conflict index (m), namely CI (f (k, m)).
A conflict index (k) for each type of conflict region, wherein the conflict index is used to characterize the conflict strength of a conflict region. The influence degree of the construction land on the subitem type spaces such as the source land and the gallery is represented by calculating the proportion of the conflict area of different types of land in the evaluation unit, and the larger the index is, the stronger the uncontrollable property of the space process is, and the larger the space conflict intensity is. The collision index for each type of collision zone is represented by:
in the formula: sceFor conflict areas, i.e. the area occupied by a certain type of space being built, SeIs the total area of this type of space.
Then constructing a strength index calculation graphical model, and accumulating all types of conflict indexes to obtain a comprehensive conflict index corresponding to the conflict area; wherein the intensity index calculation graphical model is used for calculating the intensity index of the type of the conflict region; if the comprehensive conflict index represents the accumulated intensity of different types of conflict lands in a certain space unit, if the subentry conflict index k is larger than 0, the space unit is 1, and the comprehensive conflict index is obtained by adopting a summation method, wherein the formula is as follows:
in the above formula, kiFor different types of conflict indices, i is a conflict type (i ═ 1,2,3,4), and j is a unit grid, in this example, the study area is divided into a number of regular grid units with an area of 10 hectares. Thus, for each cell grid, the resulting composite conflict index value may be 0,1,2,3,4, and when the composite conflict index value is 0, no conflict is indicated,when the integrated collision index value is 1, the collision strength is indicated to be light, when the integrated collision index value is 2, the collision strength is indicated to be medium, and when the integrated collision index value is 3 or 4, the collision strength is indicated to be high.
After obtaining the spatial collision strength index, the following steps can be performed as shown in fig. 1: s300, according to the space conflict intensity index, carrying out treatment priority division on the conflict area to obtain a treatment priority division result of the urban homeland space. Correspondingly, the step of dividing the treatment priority of the conflict area according to the space conflict intensity index to obtain the treatment priority division result of the urban homeland space comprises the following steps:
s301, obtaining an attribute value of a city homeland space; wherein the attribute values are used for representing the land use state and the building existence state of the conflict area;
s302, determining the treatment level of the conflict area through a matrix discrimination graphic model according to the attribute value and the conflict area; the matrix discrimination graphic model is used for dividing governing priorities;
s303, carrying out treatment priority division on the space conflict intensity index and the treatment grade to obtain a treatment priority division result of the urban homeland space.
Specifically, the angle of the ground surface coverage is used for analyzing the land composition and the actual situation of the ground building, and the difficulty degree of implementing treatment on the conflict space is analyzed on the basis of the strength diagnosis. The invention provides key influence factors for controlling conflict space: land attributes (including 2 indexes of land ownership and land planning) and building attributes (including 3 indexes of building type, construction age and construction strength), and the feasibility of space management is comprehensively judged in the aspect of economic cost benefit. For example, the traditional industrial factory buildings such as industry and warehouse have smaller building scale, lower removal cost and inferior commercial and office buildings, while the residential and supporting facilities need to be removed and installed, and the more economic investment, the more difficult the treatment is.
After the attribute value is obtained, determining the treatment level of the conflict area according to the attribute value and the conflict area; correspondingly, the step of determining the treatment level of the conflict area according to the attribute value and the conflict area comprises the following steps: analyzing the importance level of the attribute value; and dividing the conflict area based on the importance level to obtain the treatment level of the conflict area.
In particular, the level of importance of the government interest for the level of importance of the attribute value, such as the land property>Rights and interests of group>Equity of using ground unit>The interests of disputes. And then, based on the importance level, dividing the conflict area to obtain the treatment level of the conflict area, wherein the treatment level comprises easy treatment, easier treatment, general treatment and difficult treatment.
