Description

Technical Field

[0001] The present invention relates to the field of space governance technology, and in particular to a method, device and equipment for spatial function zoning for ecological product value transformation. Background Art

[0002] As a spatial blueprint for sustainable development, spatial planning increasingly needs to highlight its asset value and promote the preservation and appreciation of natural resources and maximize their benefits. Due to differences in natural ecological background conditions, resource endowments and actual conditions, the development direction of ecological products and the path to realize ecological value in different regions are also different. When planning leads the transformation of ecological product value, spatial guidance should be provided. The transformation of ecological product value is a response to this demand.

[0003] At present, in terms of applicable objects, the above technologies are mainly based on township units. The minimum area unit or evaluation unit formed on this basis corresponds to one or more townships. For the implementation level, the spatial scope is relatively large, and it is difficult to provide technical support for village-level spatial guidance. In addition, the division of zoning units does not fully consider the relative consistency of natural ecological conditions within the unit. In terms of technical means, the relevant technologies lack quantitative evaluation of each unit based on objective indicators and spatial means, resulting in scientificity and rationality that remain to be explored. The suitability evaluation technology for the development and utilization of ecological products is a single classification evaluation of the suitability of the development and utilization of specific types of ecological products. After the suitability evaluation of each unit is carried out separately, the evaluation results are not comprehensively compared and spatially integrated. That is, this type of technology has not finally determined the dominant direction type of ecological product value transformation of each unit. It is only a basic single evaluation and has not directly achieved the role of providing spatial guidance and planning guidance for the transformation of ecological product value in villages and towns.

[0004] To sum up, the main functional zoning for development has problems such as broad zoning types, insufficient spatial integration and refinement, and unclear indicative directions. It is difficult to directly support the transformation of ecological product value. It is necessary to explore a more implementable and conductive ecological value transformation zoning system to give full play to the spatial guidance of planning on the realization of ecological product value. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a spatial functional zoning method, device and equipment for the transformation of ecological product value, which takes into account the natural ecological integrity and planning implementation conductivity in terms of applicable objects, and realizes the comprehensive judgment of the ecological product value transformation type in terms of identification means, thereby improving the scientificity and comprehensiveness of zoning type identification.

[0006] In a first aspect, an embodiment of the present invention provides a spatial functional zoning method for ecological product value transformation, including:

[0007] Based on the extraction of watershed units in the target area using the digital elevation model corresponding to the target area, the watershed units are spatially coupled and associated with the village boundary vector data corresponding to the target area to form the basic spatial functional units for the transformation of ecological product value in the target area.

[0008] According to the pre-constructed multiple eco-product value transformation types, determine the multi-dimensional characteristic index value of the basic spatial functional unit relative to each eco-product value transformation type, and use the dynamically adjustable current index weight value to perform spatial weighted superposition processing on the multi-dimensional characteristic index value to determine the type evaluation index of the basic spatial functional unit relative to each eco-product value transformation; where the type evaluation index is used to describe the possibility that the basic spatial functional unit belongs to the eco-product value transformation type;

[0009] According to the type assessment index, the target ecological product value transformation type to which the basic spatial functional unit belongs is screened out from the ecological product value transformation types.

[0010] In one embodiment, the watershed unit and the village boundary vector data corresponding to the target area are spatially coupled and associated to form a basic spatial functional unit for the transformation of ecological product value in the target area, including:

[0011] Extract the spatial relationship between the watershed unit and the village boundary vector data corresponding to the target area to determine the spatial inclusion relationship between the village-level administrative unit and the watershed unit in the target area;

[0012] The village-level administrative units are divided according to the spatial inclusion relationship to determine the watershed unit to which each village-level administrative unit belongs;

[0013] The village-level administrative units belonging to the same watershed unit are spatially merged to form the basic spatial functional units for the transformation of ecological product value in the target area.

[0014] In one implementation, each ecological product value transformation type corresponds to characteristic index items of multiple dimensions; according to the pre-constructed multiple ecological product value transformation types, the multi-dimensional characteristic index values ​​of the basic spatial functional unit relative to each ecological product value transformation type are determined, including:

[0015] For each ecological product value transformation type, determine the importance of each characteristic indicator item corresponding to the ecological product value transformation type for the basic spatial functional unit, so as to select multiple target characteristic indicator items from each characteristic indicator item corresponding to the ecological product value transformation type according to the importance;

[0016] Obtain the characteristic index value of each target characteristic index item corresponding to each ecological product value transformation type to form the multi-dimensional characteristic index value of the basic spatial functional unit relative to each ecological product value transformation type.

[0017] In one embodiment, the types of ecological product value transformation include urban concentrated construction area type, ecological conservation and development area type, ecological cultural tourism and health care area type, ecological agricultural rural area type, and mining green transformation area type.

[0018] In one embodiment, the characteristic index items of the concentrated urban construction area type include: one or more of an urbanization rate index, a population density index, an industrial operating income proportion index, a per capita GDP index, a land development intensity index, and a road network density index;

[0019] The characteristic indicators of the ecological conservation development zone type include: one or more of the following: ecological protection red line proportion indicator, nature reserve proportion indicator, forest coverage rate indicator, soil and water loss extremely sensitive area area indicator, and land development intensity indicator;

[0022] The characteristic indicators of the mining green transformation zone type include: the proportion of mining land to construction land, the area of ​​mines to be managed, the proportion of mining industry income to regional income, and one or more of the richness of coal industry cultural resources.

[0023] In one embodiment, according to the type evaluation index, the target ecological product value transformation type to which the basic spatial functional unit belongs is screened out from the ecological product value transformation type, including:

[0024] Sort the relative sizes of the various types of evaluation indexes of each basic spatial functional unit in the target area to determine the relative ranking of the various types of evaluation indexes of each basic spatial functional unit;

[0025] For each basic spatial functional unit, the ecological product value transformation type corresponding to the type evaluation index with the highest relative ranking in the basic spatial functional unit is taken as the target ecological product value transformation type to which the basic spatial functional unit belongs.

[0026] In one embodiment, each target characteristic indicator item corresponding to each eco-product value transformation type is assigned an initial indicator weight value, and the sum of the initial indicator weight values ​​of each target characteristic indicator item corresponding to the same eco-product value transformation type is 1; the method further includes:

[0027] Displaying the target ecological product value transformation type to which the basic spatial functional unit belongs through a graphical user interface, responding to the verification operation on the target ecological product value transformation type, and adjusting the target ecological product value transformation type to which the basic spatial functional unit belongs;

[0028] The multi-dimensional characteristic index values, the current index weight values ​​of each target characteristic index item corresponding to each ecological product value transformation type, and the target ecological product value transformation type before and after adjustment are stored as empirical data in a pre-established playback pool;

[0029] The experience data stored in the playback pool is sampled to train the machine learning model using the sampled experience data, and the current indicator weight value of each target characteristic indicator item is dynamically adjusted through the trained machine learning model to obtain a new current indicator weight value; wherein, the new current indicator weight value is used to carry out spatial functional zoning of ecological product value transformation for basic spatial functional units with the same target characteristic indicator items.

[0030] In a second aspect, an embodiment of the present invention further provides a spatial function zoning device for ecological product value transformation, including:

[0031] The spatial coupling association module is used to extract the watershed units in the target area using the digital elevation model corresponding to the target area, and then spatially couple the watershed units with the village boundary vector data corresponding to the target area to form the basic spatial functional unit for the transformation of ecological product value in the target area;

[0032] An evaluation index determination module is used to determine the multi-dimensional characteristic index value of the basic spatial functional unit relative to each ecological product value transformation type according to the pre-constructed multiple ecological product value transformation types, and to perform spatial weighted superposition processing on the multi-dimensional characteristic index value using the dynamically adjustable current index weight value to determine the type evaluation index of the basic spatial functional unit relative to each ecological product value transformation; wherein the type evaluation index is used to describe the possibility that the basic spatial functional unit belongs to the ecological product value transformation type;

[0033] The type determination module is used to screen out the target ecological product value transformation type to which the basic spatial functional unit belongs from the ecological product value transformation type according to the type evaluation index.

[0034] In a third aspect, an embodiment of the present invention further provides an electronic device, comprising a processor and a memory, wherein the memory stores computer-executable instructions that can be executed by the processor, and the processor executes the computer-executable instructions to implement any one of the methods provided in the first aspect.

[0035] In a fourth aspect, an embodiment of the present invention further provides a computer-readable storage medium, which stores computer-executable instructions. When the computer-executable instructions are called and executed by a processor, the computer-executable instructions prompt the processor to implement any one of the methods provided in the first aspect.

[0036] The embodiments of the present invention provide a method, device and equipment for spatial functional zoning of ecological product value transformation. First, on the basis of extracting the watershed unit in the target area by using the digital elevation model corresponding to the target area, the watershed unit is spatially coupled and associated with the village boundary vector data corresponding to the target area to form the basic spatial functional unit of ecological product value transformation in the target area; then, according to multiple pre-constructed ecological product value transformation types, the multi-dimensional characteristic index value of the basic spatial functional unit relative to each ecological product value transformation type is determined, and the multi-dimensional characteristic index value is spatially weighted and superimposed using the dynamically adjustable current index weight value to determine the type evaluation index of the basic spatial functional unit relative to each ecological product value transformation, which is used to describe the possibility that the basic spatial functional unit belongs to the ecological product value transformation type; finally, according to the type evaluation index, the target ecological product value transformation type to which the basic spatial functional unit belongs is screened out from the ecological product value transformation type. The above method fully considers the spatial relationship between the village-level administrative units and the watershed units. The basic spatial functional units formed on this basis take into account both the natural ecological integrity and the planning implementation transmission type. The method can more effectively transmit the main functional requirements of the superior planning, and overcome the administrative boundaries that cut the integrity of the mountains, rivers, forests, fields, lakes and grasslands system. In addition, by using the dynamically adjustable current indicator weight values ​​to perform spatial weighted superposition processing on the multi-dimensional characteristic indicator values, it not only realizes the quantitative analysis of the multi-dimensional ecological product value transformation types, but also realizes the comprehensive judgment of the ecological product value transformation types, thereby improving the scientificity and comprehensiveness of the zoning type identification.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described in combination with the embodiments below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] At present, the existing technology of main functional zoning for development has problems such as broad zoning types, large spatial scale, and unclear indicative directions. It is difficult to directly support the transformation of ecological product value. It is necessary to explore a more implementable and conductive ecological value transformation zoning system to give full play to the spatial guidance of planning on the realization of ecological product value.

[0057] Based on this, the implementation of the present invention provides a spatial functional zoning method, device and equipment for the transformation of ecological product value, which takes into account the natural ecological integrity and planning implementation conductivity in terms of applicable objects, and realizes the comprehensive judgment of the value conversion functional area type in terms of identification means, thereby improving the scientificity and comprehensiveness of zoning type identification.

[0058] To facilitate understanding of this embodiment, a method for demarcating a value conversion functional area disclosed in an embodiment of the present invention is first described in detail. Figure 1 The flowchart of a spatial functional zoning method for ecological product value transformation is shown in FIG. 1 , and the method mainly includes the following steps S102 to S106:

[0059] Step S102, based on extracting the watershed units in the target area using the digital elevation model corresponding to the target area, spatial coupling association is performed on the watershed units and the village boundary vector data corresponding to the target area to form a basic spatial functional unit for the transformation of ecological product value in the target area.

[0060] Among them, the watershed unit fully depicts the relatively consistent natural ecological attributes inside and ensures the integrity of the ecosystem, while the village-level administrative division unit is the basic unit of grassroots governance and an important subject for planning implementation. The village boundary vector data is used to describe the boundary information of the village-level administrative division unit. In order to more effectively transmit the main functional requirements of the upper-level planning and overcome the cutting of the integrity of the mountains, rivers, forests, fields, lakes and grasslands by administrative boundaries, the embodiment of the present invention spatially couples the watershed unit with the village boundary vector data to form multiple basic spatial functional units, which are also the smallest units for realizing the demarcation of value conversion functional areas.

[0061] Step S104: Determine the multidimensional characteristic index value of the basic spatial functional unit relative to each ecological product value transformation type according to the pre-constructed multiple ecological product value transformation types, and use the dynamically adjustable current index weight value to perform spatial weighted superposition processing on the multidimensional characteristic index value to determine the type evaluation index of the basic spatial functional unit relative to each ecological product value transformation.

[0062] The types of ecological product value transformation include urban concentrated construction area types, ecological conservation and development area types, ecological cultural tourism and health care area types, ecological agricultural rural area types, and mining green transformation area types. Different types have different characteristic indicator systems. For example, the multi-dimensional characteristic indicators of urban concentrated construction area types include: urbanization rate index, population density index, industrial operating income proportion index, per capita GDP index, land development intensity index, and road network density index. One or more of the indicators; the multi-dimensional characteristic indicators of ecological conservation and development area types include: ecological protection red line proportion index, nature reserve proportion index, forest coverage rate index, soil and water loss extremely sensitive area area index, and land development intensity index. One or more of the indicators; ecological cultural tourism and health care area The multi-dimensional characteristic indicators of the ecological agriculture rural area type include: one or more of the following indicators: the proportion of scenic spots, the richness of cultural and tourism resources, the richness of supporting facilities resources, and the road network density; the multi-dimensional characteristic indicators of the ecological agriculture rural area type include: the proportion of agricultural production space, the proportion of the area of ​​suitable areas for agricultural production, the concentration and continuity of cultivated land, the number of types of characteristic agricultural products cultivated, the proportion of agricultural, forestry and animal husbandry income in regional income, and the protection level of characteristic mountain villages; the multi-dimensional characteristic indicators of the mining green transformation zone type include: the proportion of mining land in construction land, the area of ​​mines to be governed, the proportion of mining industry income in regional income, and the richness of coal industry cultural resources.

[0063] The type evaluation index is used to describe the possibility that the basic spatial functional unit belongs to the type of ecological product value transformation. The type evaluation index includes the urban concentrated construction index, the ecological conservation development index, the ecological cultural tourism and health care index, the ecological agriculture and rural index, and the mining green transformation index. In one example, for any ecological product value transformation type, the multi-dimensional characteristic indicators of the ecological product value transformation type can be standardized by the extreme difference, and the multi-dimensional characteristic indicator values ​​can be spatially weighted and superimposed using the dynamically adjustable current indicator weight value to obtain the type evaluation index of the basic spatial functional unit relative to the ecological product value transformation type.

[0064] Step S106: Filter out the target ecological product value transformation type to which the basic spatial functional unit belongs from the ecological product value transformation type according to the type evaluation index.

[0065] In one example, after determining the five types of evaluation indexes of the basic spatial functional units, the relative sizes of the various indexes of each basic spatial functional unit are sorted to obtain the relative ranking of each index, and then the target ecological product value transformation type of each basic spatial functional unit is determined in order from high to low relative ranking.

[0066] The spatial functional zoning method for the transformation of ecological product value provided by the embodiment of the present invention fully considers the spatial relationship between the village-level administrative units and the watershed units. The basic spatial functional units formed thereby take into account both the natural ecological integrity and the planning implementation transmission type, and can more effectively transmit the main functional requirements of the superior planning, and can overcome the administrative boundaries that cut the integrity of the mountains, rivers, forests, fields, lakes and grasslands system; in addition, by using the dynamically adjustable current indicator weight value to perform spatial weighted superposition processing on the multi-dimensional characteristic indicator values, not only the quantitative analysis of the multi-dimensional ecological product value transformation types is achieved, but also the comprehensive judgment of the ecological product value transformation types is achieved, thereby improving the scientificity and comprehensiveness of the zoning type identification.

[0067] To facilitate understanding, an embodiment of the present invention provides a specific implementation method of a spatial functional zoning method for transforming the value of ecological products.

[0068] The aforementioned step S102 specifically includes the following steps 1.1 to 1.2:

[0069] Step 1.1, extract the watershed units in the target area based on the digital elevation model corresponding to the target area.

[0070] Step 1.2: spatially couple and associate the village boundary vector data corresponding to the watershed unit and the target area to form the basic spatial functional unit in the target area.

[0071] (I) Extract the spatial relationship between the watershed unit and the village boundary vector data corresponding to the target area to determine the spatial inclusion relationship between the village-level administrative unit and the watershed unit in the target area. In one example, for any village-level administrative unit, it can be determined whether there is a spatial overlap between the village-level administrative unit and the watershed unit based on the village boundary vector data corresponding to the village-level administrative unit, and then determine the spatial inclusion relationship between the two.

[0072] (ii) The village-level administrative units are divided according to the spatial inclusion relationship to determine the watershed unit to which each village-level administrative unit belongs. In one example, if a watershed unit contains multiple village-level administrative units, it is determined that these village-level administrative units all belong to the watershed unit. In another example, the ratio between the area value of the part of the village-level administrative unit located in the watershed unit and the total area value of the village-level administrative unit can be determined. If the ratio is greater than a preset threshold, it can be determined that the village-level administrative unit belongs to the watershed unit with which it has a spatial overlapping relationship, thereby realizing the division of each village-level administrative unit in the target area. Optionally, the village-level administrative units located in the same watershed unit are identified with the same number.

[0073] (III) Spatial merging of village-level administrative units belonging to the same watershed unit to form basic spatial functional units within the target area. In one example, several village units located in the same watershed can be merged into one analysis unit, or if most of a village is in a watershed unit, and the watershed unit also involves several other villages, these village units can be merged as a whole, which also reflects the linkage development between villages. In specific implementation, the village-level administrative units with the same watershed number are spatially merged in the ArcGIS platform, thereby realizing the spatial fusion of the watershed unit and the village administrative boundary, and serving as the basic spatial functional unit for the delineation of the ecological product value transformation functional area. The ecological product value transformation functional area thus identified can also avoid discussing villages in detail, and on the basis of considering the relationship between villages and surrounding areas, it is conducive to the coordinated linkage of ecological product value transformation between villages.

[0074] For example, the embodiment of the present invention takes Mentougou District, Beijing as an example. Figure 2 The figure shows a distribution diagram of the functional areas of ecological product value transformation in Mentougou District, integrating 73 small watersheds and 194 village-level administrative units within the district, and finally identifying 127 basic spatial functional units for ecological product value transformation. Therefore, each basic spatial functional unit is a small watershed with relatively complete ecological processes and characteristic ecological resources, and is also a basic spatial guiding unit for planning and realizing ecological product value transformation and governance.

[0075] On the one hand, the embodiments of the present invention overcome the drawbacks of existing zoning identification technologies that are mainly at the county and town levels, and further sink the scale to the village-level unit; on the other hand, by considering the spatial position relationship between the village-level administrative boundaries and the watershed hydrological units, the basic spatial functional units for identifying the ecological product value transformation areas are determined, taking into account both the natural ecological integrity and the conductivity of planning implementation, and avoiding discussing villages one by one. On the basis of considering the relationship between villages and surrounding areas, it is conducive to achieving the coordinated linkage of ecological product value transformation between villages.

[0076] For the aforementioned step S104, the embodiment of the present invention provides a specific implementation method for determining each type evaluation index of each basic spatial functional unit.

[0077] First, the types of ecological product value transformation are explained. According to the overall planning of the sub-district level where the target area is located and the actual needs of regional development, such as the needs of new urbanization development, ecological protection construction, ecological cultural tourism development, ecological agriculture development, and energy transformation development, the ecological product value transformation functional area can be defined as a spatial planning guidance unit type composed of major types such as urban concentrated construction areas, ecological conservation development areas, ecological cultural tourism and health care areas, ecological agricultural rural areas, and mining green transformation areas. That is, the types of ecological product value transformation include urban concentrated construction areas, ecological conservation development areas, ecological cultural tourism and health care areas, ecological agricultural rural areas, and mining green transformation areas. Specifically:

[0078] (1) Urban concentrated construction area type: defined as a spatial unit with a good foundation and development potential in terms of population urbanization, industrial modernization, and land development. (2) Ecological conservation and development area type: defined as a spatial unit with a high ecological protection level, excellent ecological background or high ecological sensitivity, low current development intensity, and the need to strengthen ecological rigid protection and system restoration. (3) Ecological cultural tourism and health care area type: defined as a spatial unit with rich cultural tourism and health care resources and good supporting facilities. (4) Ecological agricultural rural area type: defined as a spatial unit with good agricultural production conditions, excellent rural development foundation or high village protection level. (5) Mining green transformation area type: defined as a spatial unit with sufficient mining space, mature and dominant mining industry, and rich coal industry cultural resources.

[0079] The embodiment of the present invention provides the following two methods to determine the multi-dimensional characteristic index value of the basic spatial functional unit relative to each ecological product value transformation type:

[0080] Method 1: The initial indicator weight value of the characteristic indicator item of each dimension of each ecological product value transformation type can be pre-configured, and the indicator value of the characteristic indicator item of each dimension can be spatially weighted and superimposed with the fixed initial indicator weight value to obtain a multi-dimensional characteristic indicator value. Among them, the initial indicator weight value assignment process is as follows: the weight of each indicator can be combined with the development reality such as the ecological resource endowment of the town and village and the upper-level planning positioning, combined with the AHP hierarchy analysis method, entropy method, coefficient of variation method and other weighting methods to assign or adjust the weight of the selected indicator. For ease of understanding, an embodiment of the present invention provides an implementation method for determining the type evaluation index of any ecological product value transformation type, performing range standardization processing on the multi-dimensional characteristic indicators of the basic spatial functional unit relative to the ecological product value transformation type, and performing spatial weighted superposition processing on the multi-dimensional characteristic indicators after the range standardization processing according to the preset weights to obtain the type evaluation index of the basic spatial functional unit relative to the ecological product value transformation type;

[0081] To facilitate understanding, the embodiment of the present invention takes each ecological product value transformation type as an example to explain the specific process of determining the corresponding type evaluation index.

[0082] Step 2.1: Construct an identification index system for concentrated urban construction areas and calculate the urban development and construction index:

[0083] According to the above-mentioned definition of the characteristics of concentrated urban construction areas, the evaluation and identification work is mainly carried out from the three criteria levels of population urbanization, industrial modernization, and land development degree. Six indicators are set, including urbanization rate index, population density index, industrial business income proportion index (specifically, the secondary and tertiary industry business income proportion index), per capita GDP index, land development intensity index (specifically, the land development intensity index), and road network density index, to conduct spatial quantitative analysis and expression of the suitability of urban development and construction, such as Figure 3 The figure shows a spatial schematic diagram of various characteristic indicators of a concentrated urban construction area.

[0084] Taking the basic spatial functional units as the analysis objects, the above index values ​​are extracted and spatially assigned, and then the range of each index is standardized, and further spatial weighted superposition is performed according to specific weights, so as to obtain the urban development and construction index of each basic spatial functional unit, such as Figure 4 The urban development and construction index is shown in Figure 1. The urban development and construction index calculation formula is as follows:

[0085]

[0086] In the formula, I CZKFJS is the urban development and construction index; i is the weight of the i-th indicator, CZKFJS iIt is the i-th urban development and construction evaluation index after standardized processing.

[0087] The calculation method of evaluation indexes for urban concentrated construction areas is shown in Table 1 below:

[0088] Table 1 Calculation method of evaluation indexes for concentrated urban construction areas

[0089]

[0090]

[0091] Step 2.2: Construct an identification index system for ecological conservation development zones and calculate the ecological protection compensation index:

[0092] According to the above-mentioned definition of the characteristics of the ecological conservation development zone, the evaluation and identification work is mainly carried out from the three criteria levels of ecological protection level, ecological background and sensitivity, and development status. Five indicators are set, including the proportion of ecological protection red lines, the proportion of natural reserves, the forest coverage rate, the area of ​​extremely sensitive areas for soil and water loss, and the land development intensity index. The spatial quantitative analysis and expression of the demand for ecological protection compensation are carried out, such as Figure 5 The figure shows a spatial schematic diagram of the characteristic indicators of an ecological conservation and development zone.

[0093] Taking the basic spatial functional units as the analysis objects, the above index values ​​are extracted and spatially assigned, and then the range of each index is standardized, and further spatial weighted superposition is performed according to specific weights, so as to obtain the ecological protection compensation index of each basic spatial functional unit, such as Figure 6 An ecological protection compensation index diagram is shown in Figure 1. The calculation formula of the ecological protection compensation index is as follows:

[0094]

[0095] In the formula, I STBHBC is the ecological protection compensation index; i is the weight of the i-th indicator, STBHBC i It is the ith ecological protection compensation evaluation indicator after standardization.

[0096] The calculation method of the evaluation indicators of ecological conservation development zones is shown in Table 2 below.

[0097] Table 2 Calculation method of evaluation indexes for ecological conservation development zones

[0098]

[0099] Step 2.3, construct an identification index system for ecological, cultural, tourism and health care areas and calculate the ecological, cultural, tourism and health care index:

[0100] According to the above-mentioned definition of the characteristics of the ecological cultural tourism and health care area, the evaluation and identification work is mainly carried out from two criteria levels: cultural tourism and health care resource conditions and the degree of cultural tourism supporting construction. Four indicators are set, including the area proportion index of scenic spots, the richness index of cultural tourism resources, the richness index of supporting facilities resources (specifically, the richness index of supporting facilities resources of homestay hotels), and the road network density index, to conduct spatial quantitative analysis and expression of the suitability of cultural tourism and health care development, such as Figure 7 The figure shows a spatial schematic diagram of the characteristic indicators of an ecological, cultural, tourism and health care area.

[0101] Taking the basic spatial functional units as the analysis objects, the above index values ​​are extracted and spatially assigned, and then the range of each indicator is standardized, and further spatial weighted superposition processing is performed according to specific weights, so as to obtain the cultural tourism and health development index of each basic spatial functional unit, such as Figure 8 A cultural tourism and health care development index chart is shown in Figure 1. The cultural tourism and health care development index calculation formula is as follows:

[0102]

[0103] In the formula, I WLKYFZ is the cultural tourism and health care development index; i is the weight of the i-th indicator, WLKYFZ i It is the i-th cultural tourism and health care development evaluation indicator after standardized processing.

[0104] The calculation method of the evaluation indicators of the ecological, cultural, tourism and health care area is shown in Table 3 below.

[0105] Table 3 Calculation method of evaluation indexes for cultural tourism and health care development zones

[0106]

[0107] Step 2.4, construct an identification index system for ecological agricultural rural areas and calculate the ecological agricultural rural index:

[0108] According to the above-mentioned definition of the characteristics of ecological agricultural rural areas, the evaluation and identification work is mainly carried out from three criteria levels, namely agricultural production conditions, rural development foundation, and village protection level. Six indicators are set, namely, the proportion of agricultural production space, the proportion of agricultural production suitable area, the concentration and continuity of cultivated land, the number of characteristic agricultural product cultivation types, the proportion of agricultural, forestry and animal husbandry income in regional income, and the protection level of characteristic mountain village groups in western Beijing. The spatial quantitative analysis and expression of the suitability of ecological agricultural rural development are carried out, such as Fig. 9 The figure shows a spatial schematic diagram of various characteristic indicators of an ecological agricultural rural area.

[0109] Taking the basic spatial functional units as the analysis objects, the above index values ​​are extracted and spatially assigned, and then the range of each index is standardized, and further spatial weighted superposition is performed according to specific weights, so as to obtain the ecological agriculture and rural index of each basic spatial functional unit, such as Fig.10 An ecological agriculture and rural index chart is shown in Figure 1. The calculation formula of the ecological agriculture and rural index is as follows:

[0110]

[0111] In the formula, I STNYNC is the ecological agriculture rural index; w i is the weight of the ith indicator, STNYNC i It is the i-th ecological agriculture and rural evaluation indicator after standardization.

[0112] The calculation method of the evaluation index for ecological agriculture rural areas is shown in Table 4 below.

[0113] Table 4 Calculation method of evaluation indexes for ecological agriculture rural areas

[0114]

[0115]

[0116] Step 2.5, construct the identification index system of mining green transformation zones and calculate the mining transformation development index:

[0117] According to the definition of the characteristics of the mining green transformation zone mentioned above, the evaluation and identification work is mainly carried out from the three criteria levels of mining spatial distribution, mining industry maturity, and transformation resource base. Four indicators are set, including the proportion of mining land to construction land, the area of ​​mines to be governed, the proportion of mining industry income to regional income, and the richness of coal industry cultural resources. The spatial quantitative analysis and expression of the suitability of mining transformation development are carried out, such as Fig.11 The figure shows a spatial schematic diagram of the characteristic indicators of a mining green transformation zone.

[0118] Taking the basic spatial functional units as the analysis objects, the above index values ​​are extracted and spatially assigned, and then the range of each index is standardized, and further spatial weighted superposition is performed according to specific weights, so as to obtain the mining transformation and development index of each basic spatial functional unit, such as Fig.12 A mining transformation and development index chart is shown in Figure 1. The calculation formula for the mining transformation and development index is as follows:

[0119]

[0120] In the formula, I KYZXFZ is the mining transformation and development index; i is the weight of the i-th indicator, KYZXFZi It is the i-th mining transformation and development evaluation indicator after standardized processing.

[0121] The calculation method of the evaluation indicators for the mining green transformation zone is shown in Table 5.

[0122] Table 5 Calculation method of evaluation indexes for mining green transformation zone

[0123]

[0124] Method 2: Filter the multi-dimensional characteristic indicator values ​​of target characteristic indicator items for each basic spatial functional unit, dynamically adjust the initial indicator weight value of each target characteristic indicator item, and use the dynamically adjusted current indicator weight value to perform spatial weighted superposition processing on the multi-dimensional characteristic indicator value. Specifically: (1) For each ecological product value transformation type, determine the importance of each characteristic indicator item corresponding to the ecological product value transformation type for the basic spatial functional unit, so as to select multiple target characteristic indicator items from each characteristic indicator item corresponding to the ecological product value transformation type according to the importance; (2) Obtain the characteristic indicator value of each target characteristic indicator item corresponding to each ecological product value transformation type to form the multi-dimensional characteristic indicator value of the basic spatial functional unit relative to each ecological product value transformation type; (3) Use the dynamically adjustable current indicator weight value to perform spatial weighted superposition processing on the multi-dimensional characteristic indicator value to determine the type evaluation index of the basic spatial functional unit relative to each ecological product value transformation.

[0125] In one example, for each ecological product value transformation type, for the basic spatial unit, the correlation coefficient (such as the Pearson correlation coefficient or the Spearman rank correlation coefficient) between any two characteristic index items corresponding to the ecological product value transformation type is determined, and the correlation coefficient is used to describe the characteristic index items with significant correlation, so as to screen out the target characteristic index items on this basis. In another example, a machine learning method can be used to take the historical ecological product value transformation type delineation results (that is, the historical target ecological product value transformation type) and each characteristic index item corresponding to each ecological product value transformation type as the input of the machine learning model, and the machine learning model outputs the importance corresponding to each characteristic index item, so as to screen out the target characteristic index items on this basis. In another embodiment, the characteristic index item screening method of the above two methods can also be integrated.

[0126] Furthermore, an embodiment of the present invention also provides an implementation method for dynamically adjusting the indicator weight values ​​in the aforementioned method 2, including: displaying the target ecological product value transformation type to which the basic spatial functional unit belongs through a graphical user interface, and adjusting the target ecological product value transformation type to which the basic spatial functional unit belongs in response to a verification operation on the target ecological product value transformation type to determine the final ecological product value transformation type corresponding to the basic spatial functional unit; storing the multi-dimensional characteristic indicator value, the current indicator weight value of each target characteristic indicator item corresponding to each ecological product value transformation type, and the target ecological product value transformation type before and after adjustment as experience data in a pre-established playback pool; sampling the experience data stored in the playback pool to train a machine learning model using the sampled experience data, and dynamically adjusting the current indicator weight value of each target characteristic indicator item through the trained machine learning model to obtain a new current indicator weight value; wherein the new current indicator weight value is used to perform spatial functional zoning for ecological product value transformation for basic spatial functional units with the same target characteristic indicator items.

[0127] There can be multiple playback pools. For basic spatial functional units with the same target characteristic index items, the experience data generated when performing zoning planning for these basic spatial functional units can be stored in the same playback pool. Based on this, when new experience data is generated, the new experience data can be stored in the corresponding playback pool, and the machine learning model samples and learns the experience data in the playback pool to achieve dynamic adjustment of the index weight value.

[0128] Optionally, in addition to the aforementioned methods one and two, individual indicators can also adopt the "one-vote decision-making" method according to actual conditions. For example, in the evaluation and identification of "ecological conservation and development zones", if the ecological protection level is high, that is, the "ecological protection red line ratio" is high (such as exceeding 50%), it can be directly identified as an "ecological conservation and development zone" to highlight the "ecological priority" principle.

[0129] The embodiment of the present invention sets multidimensional indicators that directly affect the value transformation of ecological products based on regional development resource endowment, spatial control constraint intensity, development goal positioning and other aspects, and spatializes them by comprehensively integrating spatial vectorization, kernel density analysis, ecological model analysis (such as USLE), and spatialization of socioeconomic data based on night light data. Through the construction of 5 indexes, spatial quantitative description and comprehensive representation of urbanization development, ecological protection compensation, cultural tourism and health development, ecological agriculture and rural development, and mining transformation development are achieved.

[0130] Furthermore, based on the actual conditions of the ecological resource endowment, ecological control constraints, etc. of towns and villages, if the evaluation unit does not involve a certain indicator (for example, if there is no richness of coal industry cultural resources, the "richness of coal industry cultural resources" indicator can be not set), or if the ecological constraints are strong in the superior planning or development positioning (such as manifested as a high "proportion of ecological protection red lines"), then it can be directly identified as an "ecological conservation development zone" in the final identification results without having to carry out too many other index evaluation and analysis.

[0131] For the aforementioned step S106, an embodiment of the present invention also provides a specific implementation method for determining the target ecological product value transformation type to which the basic spatial functional unit belongs, including: sorting the relative sizes of each type evaluation index of each basic spatial functional unit in the target area to determine the relative ranking of each type evaluation index of each basic spatial functional unit; for each basic spatial functional unit, the ecological product value transformation type corresponding to the type evaluation index with the highest relative ranking in the basic spatial functional unit is used as the target ecological product value transformation type to which the basic spatial functional unit belongs.

[0132] In the specific implementation, after calculating the indexes for the five ecological product value transformation types with different orientations, each basic spatial functional unit will obtain five indexes after range standardization, namely, urban development and construction index, ecological protection compensation index, cultural tourism and health development index, ecological agriculture development index, and mining transformation development index. In the ArcGIS platform, the relative size of each index of each basic spatial functional unit is sorted, and its ranking in the study area is marked respectively. Further, according to the relative ranking of the five indexes in each unit, the ecological product value transformation type corresponding to the highest-ranking index is taken as the preliminary judgment result, which is also the target ecological product value transformation type to which the basic spatial functional unit belongs.

[0133] In practical applications, based on the preliminary judgment results, the relevant development positioning requirements and actual needs of the zoning plan for the town can be comprehensively considered, and the ecological product value transformation functional area delineation results of each basic spatial functional unit can be obtained through expert judgment and comprehensive revision. Fig.13 The figure shows a schematic diagram of the ecological product value transformation type in Mentougou District, and finally identified 127 ecological product value functional area units, including 23 urban concentrated construction areas, 37 ecological conservation development areas, 29 ecological cultural tourism and health care areas, 21 ecological agricultural rural areas, and 16 mining green transformation areas.

[0134] The embodiment of the present invention uses a method of comprehensive ranking of the relative sizes of indices based on the spatial analysis and expression of single indexes, and conducts verification in combination with the needs of local departments and expert judgment, so as to achieve the determination of the type of ecological product value transformation.

[0135] In summary, the spatial functional zoning method for the transformation of ecological product value provided by the embodiment of the present invention has at least the following characteristics: (a) In terms of evaluation units, the embodiment of the present invention expands the spatial scale to the village-level administrative boundary, which can effectively provide spatial guidance for the transformation of ecological product value for the implementation level of national land space planning such as village planning, and has more spatial orientation significance than the existing zoning type identification technology based on the county and town scales. At the same time, the embodiment of the present invention fully considers the spatial relationship between the village unit and the small watershed unit, and the basic spatial functional unit of the ecological product value transformation functional area determined accordingly takes into account the natural ecological integrity and planning implementation conductivity, which can not only more effectively transmit the main functional requirements of the upper-level planning, but also overcome the administrative boundaries that cut the integrity of the mountains, rivers, forests, fields, lakes and grasslands system. (ii) In terms of identification methods, the embodiments of the present invention comprehensively integrate methods such as spatial vectorization, kernel density analysis, ecological model analysis (such as USLE), and spatialization of socioeconomic data based on night light data. By spatially expressing the multi-dimensional indicators that are directly related to the value transformation direction of ecological products, it not only realizes the quantitative analysis of multi-dimensional spatial suitability such as urbanization development, ecological protection compensation, cultural tourism and health development, ecological agriculture and rural development, and mining transformation and development, but also further realizes the comprehensive judgment of the type of ecological product value transformation through the comprehensive selection method of the relative size of the index, thereby improving the scientificity and comprehensiveness of zoning type identification.
