Description

Technical Field

[0001] The present invention relates to the technical field of land space regulation, and in particular to a method for dynamically generating key units for land space regulation. Background Art

[0002] National land space is an important carrier for the construction of ecological civilization. National land space remediation is a support and guarantee and a powerful tool for optimizing the national land space pattern and maintaining the high-quality development of natural resources. Existing remediation projects have been frequently adjusted and cancelled due to the lack of upper-level planning guidance in the early stage and the failure to reasonably formulate remediation goals, content and methods, which seriously affects the progress of remediation projects and prevents regional projects from being implemented and effective.

[0003] In practice, land space remediation focuses on the implementation process, and pays insufficient attention to the preparation of pre-remediation plans. The existing land space remediation methods focus on the division of remediation zoning patterns, and use remediation measures and models as a supplement to the research on remediation plans. A complete pre-remediation plan preparation system has not yet been formed, specifically:

[0004] First, the preliminary research work for the preparation of the existing land space improvement plan is not sufficient and in-depth, which limits the completeness and accuracy of the plan preparation;

[0005] 2. Affected by subjective and objective factors, the collection of relevant information elements for planning is not targeted, and the practical conversion rate is not high, which is insufficient to support the scientific and rational requirements for the preparation of the remediation plan;

[0006] 3. The compilation method is rough. The planning method for regions and areas in a certain period of time in the future is relatively rough. The model calculation and factor analysis are not comprehensive and accurate enough, and the degree of match between the remediation plan compilation results and the actual project progress is not high.

[0007] Therefore, it is necessary to further improve the prior art. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a method for dynamically generating key units for land space management with high accuracy in response to the above-mentioned existing technologies.

[0009] The technical solution adopted by the present invention to solve the above technical problems is: a method for dynamically generating key units for land space regulation, characterized by comprising the following steps:

[0010] Step 1: Formulate the survey objects and survey standards for land space improvement potential, and establish a land space improvement potential database based on the survey standards;

[0011] Step 2: Based on the national land space improvement potential database, a rolling advancement assessment model for national land space improvement areas is constructed, and the rolling advancement index of each improvement area is calculated using the rolling advancement assessment model for national land space improvement areas;

[0012] Step 3: Determine the rolling advancement order of the remediation areas according to the rolling advancement index from large to small, and combine the rolling advancement order of the remediation areas with the evaluation factors to determine the list of rolling advancement remediation areas in each county, city and district;

[0013] Step 4: Classify the potential of each remediation area according to the survey object of land space remediation potential, compare the potential of each classification in the same remediation area, and generate remediation units for each remediation area;

[0014] Step 5. Based on the rolling promotion of the remediation area list and the remediation units of each remediation area in each county, city and district, combine the conditions for setting the key units for land and space remediation to dynamically generate the key units for land and space remediation.

[0015] Preferably, the survey objects of land space improvement potential in step 1 include five categories, namely agricultural land improvement potential, village improvement potential, industrial land improvement potential, urban low-efficiency land redevelopment improvement potential and ecological protection and restoration improvement potential.

[0016] In order to improve the accuracy of the generation of key remediation units, preferably, at least one of the agricultural land remediation potential, village remediation potential, industrial land remediation potential, urban low-efficiency land redevelopment remediation potential and ecological protection and restoration remediation potential can be further subdivided into multiple subcategories.

[0017] Preferably, the remediation potential investigation standard in step 1 includes the remediation potential investigation standard corresponding to each land space remediation potential investigation object, and the specific formulation method of the remediation potential investigation standard corresponding to each land space remediation potential investigation object is:

[0019] Formulate remediation potential survey standards for village remediation potential, industrial land remediation potential, and urban low-efficiency land redevelopment remediation potential based on the “remediation object + remediation method + quality and efficiency improvement” approach;

[0020] Establish remediation potential survey standards for ecological protection, restoration and remediation based on the “damaged environment + remediation methods + functional restoration / quality improvement” approach.

[0021] Preferably, the remediation potential investigation standard in step 1 also includes a comprehensive remediation potential investigation standard, and the specific formulation method of the comprehensive remediation potential investigation standard is:

[0022] Formulate comprehensive remediation potential survey standards based on the method of “spatial ownership information + land type information + land use status + remediation type”.

[0023] Furthermore, the specific steps for establishing the land space improvement potential pool in step 1 are as follows:

[0024] Step 1-1: Guide all counties and districts to report remediation potential data according to the remediation potential survey standards and obtain a potential database;

[0025] Step 1-2: Use geographic information to process the potential data in the potential database and establish a basic database with a unified geographic information format;

[0026] Steps 1-3: Formulate potential review rules for different types of remediation, and use the formulated potential review rules to review each remediation potential data in the basic database to obtain a national land space remediation potential database.

[0027] In the present invention, the calculation formula of the rolling advancement index GDTJi of the i-th remediation area in step 2 is:

[0028] GDTJi=SYX*a+RWWC*b+HXZB*c+LDQY*d+STZS*e

The obtained land space remediation potential survey objects are recorded as remediation types, and the comprehensive governance unit is taken as the remediation unit of the corresponding remediation type in the current remediation area.

[0033] Preferably, the conditions for setting the key units for land space improvement in step 5 are at least one of the potential base, improvement basis, regional value, funding source and the willingness of the implementing entity.

[0034] Compared with the prior art, the advantages of the present invention are: on the one hand, a land space remediation potential database is established through the remediation potential survey standards, thereby providing a scientific, efficient and feasible solution for the dynamic generation of key units for land space remediation, ensuring the accuracy of the dynamic generation of key units for land space remediation; on the other hand, the list of rolling remediation areas for each county, city and district is confirmed according to the rolling advancement index; and the potential within each remediation area is graded to generate remediation units for each remediation area. Therefore, this method can realize the priority determination of land space remediation areas and the reasonable division of remediation units, thereby improving the comprehensiveness and accuracy of the generation of key units for land space remediation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 It is a flow chart of the method for dynamically generating key units of land space improvement in an embodiment of the present invention. DETAILED DESCRIPTION

[0036] The present invention is further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the method for dynamically generating key units for land space regulation in this embodiment includes the following steps:

[0038] Step 1: Formulate the survey objects and survey standards for land space improvement potential, and establish a land space improvement potential database based on the survey standards;

[0039] The survey objects of land space improvement potential include five categories, namely agricultural land improvement potential, village improvement potential, industrial land improvement potential, urban low-efficiency land redevelopment improvement potential and ecological protection and restoration improvement potential; in addition, at least one of agricultural land improvement potential, village improvement potential, industrial land improvement potential, urban low-efficiency land redevelopment improvement potential and ecological protection and restoration improvement potential can be subdivided into multiple subcategories;

[0040] In this embodiment, the survey objects of the land space improvement potential include five categories and sixteen subcategories. For example, the improvement potential of agricultural land is subdivided into six subcategories, namely: the potential for high-standard farmland construction, the potential for reclamation of cultivated land, the potential for converting dry land into paddy fields, the potential for improving the quality of other cultivated land, the potential for restoring the function of cultivated land, and the potential for concentrated and contiguous improvement of permanent basic farmland; the improvement potential of ecological protection and restoration is subdivided into seven subcategories, namely: the restoration of abandoned mines, the restoration of damaged cultivated land, the restoration of soil pollution, the comprehensive management of small watersheds, the management of sea areas and tidal flats, the restoration of wetlands, and the restoration of forest land; the subcategories of the improvement potential of villages, the improvement potential of industrial land, and the redevelopment and improvement potential of low-efficiency urban land are existing technologies, which will not be elaborated here;

[0041] The remediation potential survey standards include the remediation potential survey standards corresponding to each national land space remediation potential survey object and the comprehensive remediation potential survey standards;

[0042] The specific formulation method of the remediation potential survey standards corresponding to each land space remediation potential survey object is as follows:

[0043] According to the method of "spatial location + remediation method + remediation effect", the remediation potential survey standard of agricultural land remediation potential is formulated; for example: the spatial location in this embodiment is divided into food function production area, important agricultural product ecological protection area, permanent basic farmland protection area, cultivated land concentration area, medium and low-grade cultivated land, and the remediation method is divided into land leveling, improvement of farmland water conservancy facilities, improvement of field traffic capacity, ecological construction, terrain environment correction, irrigation facility layout, construction land reclamation, irrigation and drainage road improvement, etc.; the remediation effect is divided into the construction of stable and high-yield farmland, concentrated and contiguous farmland of 10,000 mu square, 1,000 mu square and 100 mu square;

[0044] According to the method of "remediation object + remediation method + quality and efficiency improvement", the remediation potential survey standards for village remediation potential, industrial land remediation potential and urban low-efficiency land redevelopment remediation potential are formulated; the remediation objects in this embodiment include village remediation, industrial land remediation and urban low-efficiency land redevelopment remediation. Taking village remediation as an example, for scattered "hollow villages", incomplete infrastructure and urban villages included in the transformation plan, the convenience of residents' lives is improved through remediation and evacuation, improvement of supporting facilities and urbanization transformation;

[0045] According to the method of "damaged environment + remediation method + function restoration / quality improvement", the remediation potential survey standard of ecological protection, restoration and remediation potential is formulated; in this embodiment, for mining land, excavated, collapsed, and occupied cultivated land, soil erosion on polluted land, small watersheds with ecological damage, coastlines, bays, estuaries, islands, degraded, polluted, and disaster-damaged wetlands, inefficient, degraded, and disaster-damaged forest land, etc., through classified remediation, land restoration measures, chemical, physical or biological measures, forest and grass measures, engineering measures, agricultural technology measures, and closing mountains for afforestation and other remediation methods, the restoration of farmland to forest, restoration of land use functions, improvement of ecological environment, improvement of marine ecosystem, restoration of wetland functions, and improvement of forest quality are achieved;

[0046] The specific formulation method of the comprehensive remediation potential survey standard is as follows:

[0047] The comprehensive remediation potential survey standard is formulated in the form of "spatial ownership information + land type information + land use status + remediation type". In this embodiment, spatial ownership information, land type information, land use status and five remediation types (i.e., agricultural land remediation potential, village remediation potential, industrial land remediation potential, urban low-efficiency land redevelopment remediation potential and ecological protection and restoration remediation potential) are integrated, and indicators are subdivided on this basis. Agricultural land remediation potential indicators include regional type, farmland infrastructure, arable land quality level, concentration and contiguous degree, etc.; village remediation potential indicators include village planning classification, urban development boundary conditions, remediation intention, etc.; industrial land remediation potential indicators include industrial enterprise information, industrial capacity information, environmental protection and energy-saving information, etc.; urban low-efficiency land redevelopment remediation potential indicators include approved but not supplied, supplied but not used, used but not exhausted, etc.; ecological protection and restoration potential indicators include pollution degree, ecological red line, etc.;

[0048] The specific formulation methods of the above-mentioned survey objects of land space improvement potential and the corresponding improvement potential survey standards are based on the land change survey data of the previous year as the basic database, superimposed on the management scope and the scope of the project area that has been approved for implementation, and verified and determined the potential plots on the spot in accordance with the "Technical Regulations for the Third National Land Survey". The survey objects and improvement potential survey standards are not selected subjectively by humans;

[0049] The specific steps for establishing the above-mentioned land space improvement potential pool are as follows:

[0050] Step 1-1, guide each county and city to report the remediation potential data according to the remediation potential survey standard, and obtain a potential database; in this embodiment, the potential database is obtained based on the comprehensive remediation work of the national land space;

[0051] Step 1-2: Use geographic information to process the potential data in the potential database and establish a basic database with a unified geographic information format;

[0052] In this embodiment, the geographic information format is unified into the national geodetic coordinate system of Gauss-Krüger projection, and the land area adopts the 1985 National Height Datum;

[0053] Step 1-3: formulate potential review rules for different types of remediation, and use the formulated potential review rules to review each remediation potential data in the basic database to obtain a national land space remediation potential database;

[0054] In this embodiment, the review rules are summarized as "2 types of general rules + 13 types of personalized rules", among which the general rules are the superposition of "three lines" (ecological protection red line, permanent basic farmland protection red line, urban development boundary) and restrictive factors (slope greater than 25 degrees, altitude above 500 meters), and personalized rules are formulated according to potential types. For example, the potential for cultivated land reclamation needs to deduct the scope of cultivated land or construction land changed in the previous year and the scope of land reclamation projects approved in previous years;

[0055] Step 2: Based on the national land space improvement potential database, a rolling advancement assessment model for national land space improvement areas is constructed, and the rolling advancement index of each improvement area is calculated using the rolling advancement assessment model for national land space improvement areas;

[0056] In this embodiment, the idea of ​​analytic hierarchy process is used to construct a hierarchical structure model. The analytic hierarchy process is to decompose the decision problem into different hierarchical structures in the order of the overall goal, the sub-goals of each level, the evaluation criteria and the specific alternative investment plans. Then, the priority weight of each element of each level to an element of the previous level is obtained by solving the eigenvector of the judgment matrix. Finally, the final weight of each alternative plan to the overall goal is recursively merged by the weighted sum method. The one with the largest final weight is the optimal plan.

[0057] In this embodiment, the overall goal of the decision is represented by a rolling advancement index. The higher the index is, the higher the level of priority rolling advancement is. The existing land and space improvement plan is selected to analyze the hierarchical structure model to obtain the weights corresponding to the various sub-goals that affect the overall goal of the decision in the criterion layer. In addition, in order to reduce the workload of calculation, the sub-goals corresponding to the first N weights are selected in descending order. In this embodiment, the sub-goals are suitability evaluation index, expected task completion index, core indicator index, improvement area index and ecological restoration key area index. In addition, the weights of the existing land and space improvement plan for each sub-goal are recalculated to obtain the following rolling advancement index calculation formula;

[0058] In this embodiment, the calculation formula of the rolling advancement index GDTJi of the ith remediation area is:

[0059] GDTJi=SYX*a+RWWC*b+HXZB*c+LDQY*d+STZS*e

[0060] Wherein, SYX is the suitability evaluation index, RWWC is the expected task completion index, HXZB is the core indicator index, LDQY is the remediation area index, STZS is the ecological restoration key area index, a, b, c, d and e are the weights of SYX, RWWC, HXZB, LDQY and STZS respectively, a∈[0,1], b∈[0,1], c∈[0,1], d∈[0,1], e∈[0,1], and a+b+c+d+e=1; in this embodiment, a, b, c, d and e are determined by qualitative analysis of the rolling advancement index of the national land space, a=0.2, b=0.3, c=0.3, d=0.1, e=0.1;

[0061] The calculation formula of SYX is: SYX = SYXi / SYXmax; SYXi is the suitability evaluation index of the i-th remediation area, SYXi = SYQLi / Qli, SYQLi is the area with potential located in the corresponding suitable area, Qli is the potential area; SYXmax is the maximum value of the suitability evaluation index of all remediation areas;

[0062] The calculation formula of RWWC is: RWWC = RWWCi / RWWCmax, where RWWCi is the expected completion index of the task in the i-th remediation area. RxF ij is the estimated completion index of the jth task in the ith remediation area, n is the total number of tasks in the ith remediation area, RWLX ij =QL ij / FJMBij,QL ij is the potential value of the jth task of the ith remediation area, FJMBij is the decomposed target value of the jth task of the ith remediation area, FJMBij=SDRWij*(PQi / XZQi), SDRWij is the target value of the jth task to be completed by the administrative district corresponding to the ith remediation area, PQi is the area of ​​the ith remediation area, and XZQi is the area of ​​the administrative district corresponding to the ith remediation area;

[0063] The calculation formula of HXZB is: HXZB = HXZBi / HXZBmax, HXZBi is the sum of the five core indicators of the remediation area, and HXZBmax is the maximum value of the sum of the five core indicators of the remediation area;

[0064] The calculation formula of LDQY is: LDQY = LDQYi / LDQYmax; LDQYi is the proportion of the area of ​​the i-th remediation area in the six major regions, that is, the percentage of the overlapping area of ​​each remediation area and the six major regions in the remediation area; LDQYmax is the maximum proportion of the area of ​​the remediation area in the six major regions;

[0065] The calculation formula of STZS is STZS = STZSi / STZSmax, where STZSi is the proportion of the area of ​​the i-th remediation area located in the key remediation area in the special plan for ecological restoration, that is, the percentage of the overlapping area of ​​each remediation area and the key remediation area in the special plan for ecological restoration in the remediation area; STZSmax is the maximum proportion of the area of ​​the remediation area located in the key remediation area in the special plan for ecological restoration;

[0066] Step 3: Determine the rolling advancement order of the remediation areas according to the rolling advancement index from large to small, and combine the rolling advancement order of the remediation areas with the evaluation factors to determine the list of rolling advancement remediation areas in each county, city and district;

[0067] In this embodiment, the evaluation factors include at least one of the positioning of the remediation area, the main functional area planning of the county, city, and district, the overall national land space planning, and the willingness of the implementing entity;

[0068] Step 4: Classify the potential of each remediation area according to the survey object of land space remediation potential, compare the potential of each classification in the same remediation area, and generate remediation units for each remediation area;

[0069] Guided by planning, the smallest unit (administrative village) of the superior planning is implemented, the requirements of the division of management powers are followed, and the potential base library of remediation potential is used as the data basis. The potential quantity of each administrative village in the area is rolled forward according to the total remediation potential, agricultural land remediation potential, village remediation potential, industrial land remediation potential, low-efficiency land remediation potential and ecological restoration potential. The potential of the area is graded according to the natural breakpoint method for the six types of potential (total remediation potential, agricultural land remediation potential, village remediation potential, industrial land remediation potential, low-efficiency land remediation potential and ecological restoration potential);

[0070] The specific generation method of the remediation unit in each remediation area is as follows:

[0071] The administrative village with the highest total potential level in a single remediation area is taken as a comprehensive remediation unit, and the potential of all the land space remediation potential survey objects in the comprehensive remediation unit is ranked from high to low, and the land space remediation potential survey objects corresponding to the top N potentials after ranking are obtained, where N is a positive integer ≥ 1. The obtained land space remediation potential survey objects are recorded as remediation types, and the comprehensive remediation unit is taken as the remediation unit of the corresponding remediation type in the current remediation area;

[0072] In this embodiment, N=2, that is, the administrative village units of the highest and second highest remediation types among the agricultural land remediation potential, village remediation potential, industrial land remediation potential, low-efficiency land remediation potential and ecological restoration potential are defined as remediation units of the corresponding remediation type;

[0073] Step 5: Based on the rolling promotion of the list of remediation areas and the remediation units of each remediation area in each county, city and district, the key units of land and space remediation are dynamically generated in combination with the conditions set for the key units of land and space remediation;

[0074] The setting conditions of the key units of land space improvement in this embodiment are at least one of the potential base, improvement basis, regional value, funding source and the willingness of the implementing entity.

[0075] In addition, the scope of the remediation project planned by the local government and the scope of the designated remediation unit are superimposed and analyzed, and the rationality of the dynamically generated key units for national land space remediation is verified based on the overlap ratio (overlapping area / rolling advancement unit area) and implementation status to complete the rationality test.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
