Obviously, the described embodiments are only 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.

[0047] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0049] In a first aspect, an embodiment of the present invention provides a visualization method for natural resource assessment, see Figure 1 , which is a flow chart of an embodiment of a visualization method for natural resource assessment provided by the present invention.

[0050] like Figure 1 As shown, the method comprises the following steps:

[0051] Obtain natural resource data for each type of natural resource in the area to be assessed;

[0052] Using a pre-constructed evaluation index system, the natural resource data is divided into levels to obtain a level division result; wherein the levels are respectively a strict protection level, an ecological improvement level and a suitable development level in order of development suitability from low to high;

[0053] According to the evaluation index system, the natural resource data in each level is visualized to obtain a number of index evaluation graphs;

[0054] A spatial overlay analysis is performed on all the indicator evaluation maps in each level to obtain spatial visualization partition result maps of all levels.

[0055] In the specific implementation, we first collect detailed data on various natural resources in the area to be evaluated. These data cover key information such as the type, quantity, quality and spatial distribution of natural resources. We use the pre-constructed evaluation index system to scientifically and rationally divide these natural resource data into levels, and divide the resources into strict protection level, ecological improvement level and suitable development level in order of development suitability from low to high. Among them, development suitability refers to the adaptability and potential of natural resources to a certain development purpose. According to the various indicators in the evaluation index system, the natural resource data in each level are visualized to generate multiple intuitive indicator evaluation maps. All indicator evaluation maps in each level are spatially overlaid and analyzed, thereby integrating the spatial visualization zoning result maps of each level.

[0056] In summary, the present invention obtains natural resource data of various types of natural resources in the area to be evaluated; uses a pre-constructed evaluation index system to divide the natural resource data into levels to obtain a hierarchical division result; wherein the levels are, in order of development suitability from low to high, strict protection level, ecological improvement level and suitable development level; according to the evaluation index system, the natural resource data in each level are visualized to obtain a number of indicator evaluation maps; all the indicator evaluation maps in each level are spatially superimposed and analyzed to obtain spatial visualization partition result maps of all levels; the present invention can realize the visualization presentation of the evaluation results, and the visualization technology can convert complex natural resource data into intuitive and easy-to-understand graphics and images, which can help decision makers to understand the resource distribution, quality and potential more clearly, and help to more accurately judge which resources have higher protection value and which resources have greater development potential, so as to formulate development, protection, restoration and remediation strategies in a targeted manner, which provides an important basis for the optimal allocation of resources and can promote the rational use and sustainable development of resources.

[0057] In an optional implementation, the natural resource data includes but is not limited to at least one of land resource data, forest resource data, grassland resource data, mineral resource data, marine resource data, wetland resource data and water resource data.

[0058] Specifically, the natural resource data should be closely linked with the latest results of the land survey, achieve full coverage, and comprehensively include all key natural resource elements, including but not limited to at least one of land resource data, forest resource data, grassland resource data, mineral resource data, marine resource data, wetland resource data and water resource data, so as to provide a detailed, accurate and comprehensive basis for the spatial distribution of natural resources, and lay the foundation for subsequent resource assessment, management and protection work.

[0059] In an optional implementation, the evaluation indicators of the strict protection level include ecological protection red line indicators, permanent basic farmland protection red line indicators and urban development boundary indicators; the evaluation indicators of the ecological improvement level include natural resource asset development and utilization status indicators, natural resource quality grade indicators and natural resource asset area indicators; the evaluation indicators of the suitable development level include natural resource asset ownership indicators and ecological asset value indicators.

[0060] Specifically, the evaluation index system is mainly divided into strict protection level, ecological improvement level and appropriate development level. Corresponding evaluation indicators are set for each level. The evaluation indicators of the strict protection level focus on the protection needs of resources, mainly including ecological protection red line indicators, permanent basic farmland protection red line indicators and urban development boundary indicators. These indicators aim to delineate areas where development activities need to be strictly restricted in order to protect the integrity of the ecosystem, the permanence of farmland and the orderliness of urban development. Through the evaluation of these indicators, it can be clarified which areas must remain in their original state or be specially protected to prevent over-development and resource destruction.

[0061] Furthermore, the assessment indicators at the ecological improvement level focus on the sustainable use of resources and ecological restoration, including indicators for the current status of natural resource asset development and utilization, natural resource quality grade indicators, and natural resource asset area indicators. These indicators are used to identify areas that are currently underutilized or of poor quality but whose ecological value and resource benefits can be improved through reasonable management and ecological restoration measures. Through the assessment of these areas, targeted ecological improvement strategies can be formulated to promote the sustainable use of resources and the restoration of ecosystems.

[0062] Furthermore, the evaluation indicators for the appropriate development level focus on the economic value and development potential of resources, mainly including natural resource asset ownership indicators and ecological asset value indicators. These indicators are used to evaluate which areas are suitable for moderate development activities under the premise that the ownership of natural resources is clear, the ecological asset value is high, and the impact of development activities on the ecosystem is controllable. Through the evaluation of these indicators, it can be determined which areas can achieve sustainable economic and social development while protecting the ecological environment.

[0063] The evaluation system of the present invention sets evaluation indicators at different levels, and divides the natural resource data of the area to be evaluated into a strict protection level, an ecological improvement level, and a suitable development level, thereby realizing refined management of the protection and utilization of natural resources.

[0064] In an optional implementation, the natural resource data is divided into levels using a pre-built evaluation index system to obtain a level division result, including:

[0065] The natural resource data is evaluated using the highest level evaluation index in the evaluation index system to obtain an evaluation result;

[0066] Performing spatial assignment on the evaluation result to obtain an assignment result; wherein the assignment result includes a first assignment result and a second assignment result;

[0067] When the assignment result is the first assignment result, the natural resource data is divided into levels to which the corresponding evaluation indicators belong;

[0068] When the assignment result is the second assignment result, continue to use the next evaluation indicator of the current level for evaluation until the assignment result is the first assignment result, and divide the natural resource data into levels to which the corresponding evaluation indicators belong; wherein, if the current level does not have the next evaluation indicator, use the evaluation indicator of the next level higher than the current level for evaluation.

[0069] Specifically, the evaluation indicators in the pre-constructed evaluation indicator system are used to divide the natural resource data into corresponding levels. The evaluation results of each evaluation indicator are expressed in the form of spatial assignment. There are only two spatial assignment results, namely, the first assignment result is 0 and the second assignment result is 1. First, the ecological protection red line indicators of the strict protection level in the evaluation indicator system are used for evaluation, and the evaluation results are spatially assigned. If the spatial assignment result is 0, it is divided into the strict protection level corresponding to the ecological protection red line indicators. If the spatial assignment result is 1, it is necessary to further investigate other evaluation indicators and use the next evaluation indicator of the current level for evaluation, namely, the permanent basic farmland protection red line indicator, and repeat the spatial assignment steps. This process will continue until the assignment result becomes the first assignment result 0, and the natural resource data is divided into the level to which the corresponding evaluation indicator belongs.

[0070] It is understandable that if there is no next evaluation indicator available at the current level, but the assignment result is still the second assignment result 1, the evaluation indicator of the next level higher than the current level will be used for evaluation. For example, if the urban development boundary indicator is used for evaluation and the spatial assignment result of the evaluation result is 1, the natural resource asset development and utilization status indicator of the ecological improvement level will be used to continue the evaluation. If the evaluation indicator is the last evaluation indicator of the last level, but the spatial assignment result is still 1, it will be classified as the previous level. Through this series of evaluation and classification steps, natural resource data can be accurately divided into different levels, providing strong support for subsequent resource management and planning.

[0071] In an optional implementation, when the level is a strict protection level, the natural resource data in each level is visualized according to the evaluation index system to obtain a number of index evaluation graphs, including:

[0072] Obtain data on natural resources in the strict protection level;

[0073] Assigning values ​​to the natural resource data according to the ecological protection red line indicators, and generating an ecological protection red line indicator assessment map using ArcGIS software based on the ecological protection red line assignment results;

[0074] Assigning values ​​to the natural resource data according to the permanent basic farmland protection red line index, and generating a permanent basic farmland protection red line index assessment map using ArcGIS software based on the permanent basic farmland protection red line assignment results;

[0075] The natural resource data are assigned values ​​according to the urban development boundary indicators, and based on the urban development boundary assignment results, ArcGIS software is used to generate an urban development boundary indicator evaluation map.

[0076] Specifically, when the level is the strict protection level, the natural resource data in the strict protection level is obtained, and the spatial data located within the ecological protection red line is assigned a value of 0, and the spatial data located outside the ecological protection red line is assigned a value of 1 using ArcGIS software to obtain the ecological protection red line indicator evaluation map; the spatial data located within the permanent basic farmland protection red line is assigned a value of 0, and the spatial data located outside the permanent basic farmland protection red line is assigned a value of 1 to obtain the basic farmland protection red line indicator evaluation map; the spatial data located within the urban development boundary is assigned a value of 0, and the spatial data located outside the urban development boundary is assigned a value of 1 to obtain the urban development boundary indicator evaluation map.

[0077] In an optional implementation, when the level is an ecological improvement level, the natural resource data in each level is visualized according to the evaluation index system to obtain several index evaluation graphs, including:

[0078] Obtaining natural resource data in the ecological improvement level;

[0079] Assigning values ​​to the natural resource data according to the current status indicators of development and utilization of natural resource assets, and using ArcGIS software to generate an assessment map of the current status indicators of development and utilization of natural resource assets based on the results of the assignment of the current status indicators of development and utilization of natural resource assets;

[0080] Assigning values ​​to the natural resource data according to the natural resource quality grade index, and generating a natural resource quality grade index evaluation map using ArcGIS software based on the natural resource quality grade assignment result;

[0081] The natural resource data is assigned a value according to the natural resource asset area index, and based on the natural resource asset area assignment result, ArcGIS software is used to generate a natural resource asset area index assessment map.

[0082] Specifically, when the level is the ecological improvement level, the natural resource data in the ecological improvement level is obtained, and the spatial data of natural resources that have been developed, utilized and constructed are assigned a value of 0 using ArcGIS software, and the spatial data of natural resources that have not been developed, utilized and constructed are assigned a value of 1, so as to obtain an evaluation map of the current status of natural resource asset development and utilization indicators, the spatial data of the four-level forest land quality in the natural resource data are assigned a value of 0, the spatial data of the first, second and third level forest land quality are assigned a value of 1, the spatial data of cultivated land of levels 13-15 quality are assigned a value of 0, the spatial data of cultivated land of levels 1-12 quality are assigned a value of 1, the spatial data of water areas of Class IV and Class V water quality are assigned a value of 0, the spatial data of water areas of Class I, II and III water quality are assigned a value of 1, and other spatial data except forest land, cultivated land and water areas are assigned a value of 1, so as to obtain a natural resource quality grade indicator evaluation map, the spatial data of a single natural resource asset continuous map area less than the defined value are assigned a value of 0, and the natural resource asset map areas of a single natural resource asset continuous map area not less than the defined value are assigned a value of 1, so as to obtain a natural resource asset area indicator evaluation map.

[0083] It should be noted that according to the afforestation carbon sink methodology, the continuous area of ​​a single plot of land in an afforestation carbon sink project should not be less than 400m 2 For projects started before 2019 (inclusive), the continuous land area is not less than 667m 2 According to the Technical Regulations for the Third National Land Survey, the minimum area of ​​agricultural land (excluding facility agricultural land) is 400m2. 2 Based on the above documents, the reference value of the natural resource asset area index is 500m 2 , those skilled in the art may select other values ​​according to the specific evaluation area and requirements, and no specific limitation is made here.

[0084] In an optional implementation, when the level is a suitable development level, the natural resource data in each level is visualized according to the evaluation index system to obtain a number of index evaluation graphs, including:

[0085] Obtaining data on natural resources at the level suitable for development;

[0086] Assigning values ​​to the natural resource data according to the natural resource asset ownership index, and generating a natural resource asset ownership index assessment map using ArcGIS software based on the natural resource asset ownership assignment result;

[0087] The natural resource data is assigned a value according to the ecological asset value index, and based on the ecological asset value assignment result, ArcGIS software is used to generate an ecological asset value index evaluation map.

[0088] Specifically, when the level is a suitable development level, obtain the natural resource data in the suitable development level, use the ArcGIS software to assign a value of 0 to the spatial data with clear ownership, use rights, etc. of natural resources, and assign a value of 1 to the spatial data with unclear or disputed ownership, use rights, etc. of natural resources, to obtain a natural resource asset ownership index assessment map.

[0089] Regarding the ecological asset value index assessment map, it should be noted that, in combination with the land survey classification system and the natural resource classification system, and referring to the national or local ecological asset value assessment standards and specifications applicable to the area to be assessed, different resource plots in the natural resource data are calculated separately, and the attribute connection of ArcGIS software is used to assign them to the corresponding land classification spatial data, so as to obtain the spatial visualization results of the ecological asset values ​​of various types of resource plots, and the natural breakpoint method is used to divide the ecological asset value spatial visualization results into three levels from high to low, among which the ecological asset value corresponding to the first level is the highest, and the spatial data with the ecological asset value spatial visualization results of the first and second levels are assigned a value of 0, and the spatial data with the ecological asset value spatial visualization results classified as the third level are assigned a value of 1, so as to obtain the ecological asset value index assessment map.

[0090] In an optional implementation, a spatial overlay analysis is performed on all indicator evaluation maps in each level to obtain spatial visualization partition result maps of all levels.

[0091] For example, for the strict protection level, the spatial visualization results of the ecological protection red line indicators, permanent basic farmland protection red line indicators and urban development boundary indicators of this level are spatially superimposed and analyzed to obtain the spatial visualization zoning result map of the strict protection level. The spatial superposition analysis method used is:

[0092] DP =EP0+FP0+UB0;

[0093] Among them, D P Represents the zoning spatial data of the strict protection level, EP0 is the spatial data area where the ecological protection red line indicator evaluation result is 0, FP0 is the spatial data area where the permanent basic farmland protection red line indicator evaluation result is 0, and UB0 is the spatial data area where the urban development boundary indicator evaluation result is 0.

[0094] For the ecological improvement level, the spatial visualization results of the current status indicators of natural resource asset development and utilization, natural resource quality grade indicators and natural resource asset area indicators of this level are spatially superimposed and analyzed to obtain the spatial visualization zoning result map of the ecological improvement level. The spatial superposition analysis method used is:

[0095] D DU =D A -D O ;

[0096] D Uα =(CS0+QL0+SZ0)∩D DU ;

[0097] D U =D Uα +D Uβ ;

[0098] Among them, D DU To improve the level of natural resources in the ecosystem, D A is the total natural resource base data of the area to be assessed, D P To strictly protect the hierarchical partition space data, D Uα is the preliminary spatial data of the ecological improvement level. CS0 is the spatial data area where the evaluation result of the current status of natural resource asset development and utilization index is 0. QL0 is the spatial data area where the evaluation result of the natural resource quality grade index is 0. SZ0 is the spatial data area where the evaluation result of the natural resource asset area index is 0. U To improve the level of ecological partitioning spatial data, D Uβ Supplement data for the zoning space to upgrade the ecological level.

[0099] For the suitable development level, the spatial visualization results of the natural resource asset ownership indicators and ecological asset value indicators of this level are spatially superimposed and analyzed to obtain the spatial visualization zoning result map of the suitable development level. The spatial superposition analysis method used is:

[0100] D DE =D DU -D Uα ;

[0101] D E =(BL0+VL0)∩D DE ;

[0102] Among them, D DE To obtain the natural resource base data at the appropriate development level, D DU To improve the level of natural resources in the ecosystem, D Uα Preliminary data of the zoning space for ecological upgrading, D E For the zoning spatial data of the appropriate development level, BL0 is the spatial data area where the evaluation result of the natural resource asset ownership index is 0, and VL0 is the spatial data area where the evaluation result of the ecological asset value index is 0.

[0103] Furthermore, other spatial data that are not classified as suitable for development are classified into the next level, namely the ecological improvement level, which is as follows:

[0104] D Uβ =D DE -D E ;

[0105] Among them, D Uβ Supplement data for the partition space of ecological upgrading level, D DE To obtain the natural resource base data at the appropriate development level, D E Zoning spatial data for appropriate development levels.
