[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0035] Currently, based on the need for ecosystem carbon sink regulation, more and more research is being applied to the estimation of ecosystem carbon sink potential.

[0036] However, current research on the potential for consolidating and enhancing carbon sequestration capacity mainly focuses on single ecosystems or local ecosystems, while research on the potential for consolidating and enhancing carbon sequestration capacity on a large scale in preset regions such as the whole country is relatively weak.

[0037] Furthermore, research results on the potential for strengthening and enhancing carbon sequestration capacity are subject to significant uncertainty due to factors such as data sources, research scales, and methods, as well as differences in ecosystem types and regions. Estimation of the potential for strengthening and enhancing carbon sequestration capacity across national ecosystems, which is subject to unified oversight, is lagging behind. The actual potential and key areas for strengthening and enhancing carbon sequestration capacity remain unclear, hindering efforts to strengthen and enhance carbon sequestration capacity and enhance the synergy and effectiveness of ecological development.

[0038] Therefore, in view of the current deficiencies in estimating the potential for consolidating and improving carbon sink capacity, it is urgent to develop an estimation method for the actual potential for consolidating and improving carbon sink capacity for unified supervision.

[0039] Based on this, the embodiments of the present invention provide a method and device for estimating the potential for consolidating and improving carbon sink capacity for unified supervision, which can effectively alleviate the above technical problems.

[0040] To facilitate understanding of this embodiment, a method for estimating the potential for consolidating and improving carbon sink capacity for unified supervision disclosed in an embodiment of the present invention is first introduced in detail.

[0041] In a possible implementation, the present invention provides a method for estimating the potential for consolidation and enhancement of carbon sink capacity for unified supervision, such as Figure 1 The flowchart of a method for estimating the potential for consolidation and enhancement of carbon sequestration capacity for unified supervision is shown, and the method includes the following steps:

[0042] Step S102, collecting basic data within a preset area;

[0043] In the embodiment of the present invention, the basic data includes multiple land patches within a preset area and ecological data of each land patch, and the ecological data is used to evaluate the ecosystem carbon sink of the land patch.

[0044] Specifically, the ecosystem carbon sink in the embodiment of the present invention refers to the green plants absorbing carbon dioxide from the atmosphere through photosynthesis and fixing it in the plant body or soil. The more organic matter the plants form through photosynthesis, the stronger the ecosystem carbon sink capacity; conversely, the weaker the ecosystem carbon sink capacity.

[0045] Moreover, ecosystem carbon sink is one of the service functions formed by the growth and development process of plants in the ecosystem, and plant photosynthesis is the common mechanism and fundamental mechanism of carbon sinks in various ecosystems. Therefore, in the embodiment of the present invention, the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year is used as a measure of ecosystem carbon sink, which can avoid the problems of spatial discontinuity, duplication, omission, etc. in the estimation of the potential for consolidating and improving carbon sink capacity due to inconsistencies in the time, cycle, and scope of various resource surveys and monitoring. Moreover, the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year is used as a measure of ecosystem carbon sink, which can reflect the influence of factors such as climate, soil, topography, and vegetation type on plant growth and development, and reflect the changing trend and regional differences in the carbon sink capacity of the ecosystem, and meet the needs of scientifically demarcating key areas for consolidating and improving the potential for carbon sink capacity for unified supervision, and establishing and implementing an ecosystem carbon sink supervision system with the goal of spatial control and quality improvement.

[0046] Step S104: Based on the basic data, the actual potential for consolidation and improvement of the carbon sequestration capacity of each land patch is estimated, taking the land patch as the spatial unit and the preset time interval as the time unit;

[0047] Step S106, screening each land patch based on actual potential according to pre-set delineation standards to obtain key patches with potential for consolidating and improving carbon sequestration capacity;

[0048] Step S108: Aggregate the key patches to obtain key areas with the potential for consolidating and improving carbon sequestration capacity.

[0049] In actual use, the above-mentioned preset areas usually cover multiple land patches, so as to achieve spatial continuity in the estimation of the potential for consolidating and improving carbon sequestration capacity. In addition, in step S108, by aggregating key patches, key areas with the potential for consolidating and improving carbon sequestration capacity are obtained, which can provide a scientific basis for establishing and implementing an ecosystem carbon sink supervision system with the goals of spatial control and quality improvement.

[0050] In actual use, in order to evaluate the ecosystem carbon sink of land patches, in an embodiment of the present invention, the ecological data in the above step S102 usually include remote sensing images covering the land patches, image-derived data, and administrative divisions, ecosystem types, vegetation types and other data, thereby constituting the basic data for estimating the actual potential for consolidating and improving carbon sink capacity for unified supervision in an embodiment of the present invention.

[0051] Among them, remote sensing data and image-derived data include net primary productivity data of plants covering a certain area; vegetation types are derived from vegetation maps provided by research departments, and ecosystem types can refer to the ecosystem classification of remote sensing surveys and assessments of ecological conditions in a certain area, which usually include forests, shrubs, grasslands, wetlands, farmlands, towns, deserts and bare land. Administrative division data can refer to the administrative division data sets published by current government departments, etc., and in order to make the carbon sequestration capacity consolidation and enhancement potential estimation method for unified supervision in the embodiment of the present invention have certain timeliness and reference value, usually, the most recent past certain years can be determined as a preset time period, such as the past ten or twenty years, and one year can be used as a preset time interval. The above ecological data can be sorted according to the preset time period or preset time interval.

[0052] Furthermore, for the aforementioned ecological data, or basic data, a geographic information system (GIS) can be used to preprocess the collected data, including data format conversion, projection conversion, resampling, spatial interpolation, etc. After preprocessing, all data are unified into the same coordinate system and image resolution to facilitate use and calculation in subsequent steps.

[0053] The specific ecological data and the specific implementation of data preprocessing can be set according to actual usage conditions, and the embodiment of the present invention does not limit this.

[0054] Furthermore, after obtaining the above basic data, we can first evaluate the ecosystem carbon sink of each land patch, and then further estimate the potential for consolidating and improving carbon sink capacity based on the ecosystem carbon sink.

[0055] Specifically, when evaluating ecosystem carbon sinks, the area of the land patch, the conversion coefficient of plant biomass to carbon, biomass density, plant loss coefficient, and plant net primary productivity can be determined based on ecological data to determine the carbon absorption amount, and then the ecosystem carbon sink of each land patch can be evaluated based on the carbon absorption amount, so as to further estimate the actual potential for consolidating and improving the carbon sink capacity of each land patch.

[0056] The specific method of evaluating the carbon absorption amount can be set according to actual usage conditions, and the embodiment of the present invention is not limited to this.

[0057] For ease of understanding, in the above Figure 1 On the basis of Figure 2 A flowchart of another method for estimating the potential for consolidation and improvement of carbon sequestration capacity for unified supervision is also shown, which further describes the estimation process of the actual potential for consolidation and improvement of carbon sequestration capacity of each land patch, such as Figure 2 As shown, the following steps are included:

[0058] Step S202, collecting basic data within a preset area;

[0059] In the embodiment of the present invention, the basic data includes multiple land patches within a preset area and ecological data of each land patch, and the ecological data is used to evaluate the ecosystem carbon sink of the land patch.

[0060] Step S202: evaluating the carbon absorption amount of each land patch at each time interval within a preset time period based on the ecological data of each land patch in the basic data, and determining the carbon absorption amount as the ecosystem carbon sink of the land patch at the time interval;

[0061] Among them, the preset time period in the embodiment of the present invention is greater than the preset time interval; for example, taking the period from 2000 to 2022 as an example, the preset time period is expressed as the period from 2000 to 2022, and the preset time interval can be expressed as every year.

[0062] Step S204, determining the maximum value of the ecosystem carbon sink of the land patch based on the ecosystem carbon sink corresponding to the land patch at the time interval; and

[0063] Step S206, calculating the actual potential for consolidating and improving the carbon sequestration capacity of the land patch based on the ecosystem carbon sequestration corresponding to the time interval of the land patch and the maximum value of the ecosystem carbon sequestration of the land patch;

[0064] Specifically, in step S206, when calculating the actual potential for consolidating and improving the carbon sequestration capacity of a land patch, the difference between the maximum carbon sequestration value of the ecosystem of the land patch and the ecosystem carbon sequestration value of the land patch corresponding to the time interval can be calculated; and the difference is then determined as the actual potential for consolidating and improving the carbon sequestration capacity of the land patch;

[0065] The difference is calculated according to the following formula:

[0066] PCS i =MACS i -CS in

[0067] Among them, PCS i represents the actual potential for consolidation and improvement of the carbon sequestration capacity of the i-th land patch, CS in is the ecosystem carbon sink of the i-th land patch in the n-th time interval, MACS i is the maximum value of ecosystem carbon sink of the i-th land patch in the preset time period, and MACS i Expressed as:

[0068] MACS i =MAX(CS i1 , CS i2 ,…,CS in ).

[0069] Specifically, the preset area is the corresponding national land area, the preset time period is the period from 2000 to 2022, and the preset time interval is annual. In this case, n represents the year, and the nth year represents the current year of the ecosystem carbon sink assessment. in is the ecosystem carbon sink and MACS of the i-th land patch in the current year i is the maximum value of ecosystem carbon sink in the i-th land patch; PCS i It is the actual potential for consolidating and improving the carbon capacity of the i-th land patch, and usually PCSi≧0.

[0070] Furthermore, after calculating the actual potential for consolidating and improving the carbon sequestration capacity of each land patch based on the above method, the following steps can be further performed to screen the land patches based on the actual potential.

[0071] Step S208, screening each land patch in turn to see if its actual potential is greater than a preset demarcation standard;

[0072] Step S210, determining the land patches whose actual potential is greater than the preset demarcation standard as key patches;

[0073] Step S212: Aggregate the key patches to obtain key areas with the potential for consolidating and improving carbon sequestration capacity.

[0074] In specific implementation, the demarcation standard in step S208 is generally obtained in the following manner:

[0075] (1) Obtain the actual potential for consolidating and improving the carbon sequestration capacity of each land patch within the preset area;

[0076] (2) Calculate the average value of the actual potential of each land patch based on the actual potential of each land patch to consolidate and improve its carbon sequestration capacity;

[0077] (3) The average value is determined as the demarcation standard.

[0078] Specifically, the calculation formula of the demarcation standard can be expressed as:

[0079]

[0080] Among them, m is the total number of land patches in the preset area;

[0081] This delineation standard is also known as the key area delineation standard for consolidating and enhancing the potential for carbon sequestration capacity.

[0082] In actual use, the processing function of ArcGIS raster data can be used to identify key patches with actual potential for consolidating and improving carbon sequestration capacity, namely PCS i >PCSA patches. The actual potential for consolidating and improving carbon sequestration capacity in these patches is usually higher than the average level of the pre-set region. For example, if the pre-set region is the corresponding national territory, the actual potential for consolidating and improving carbon sequestration capacity in these selected patches is higher than the national average level. These patches are key areas for continuously consolidating and improving carbon sequestration capacity and for ecosystem carbon sequestration supervision.

[0083] Furthermore, in the above step S212, when aggregating key patches, the aggregation function of ArcGIS can also be used to aggregate key patches with potential for consolidating and improving carbon sequestration capacity, and obtain key areas with potential for consolidating and improving carbon sequestration capacity; at the same time, using the conversion tool of ArcGIS data format, it can be converted into a vector range of key areas with potential for consolidating and improving carbon sequestration capacity for unified supervision, providing a scientific basis for establishing and implementing an ecosystem carbon sequestration supervision system with the goals of spatial control and quality improvement.

[0084] Furthermore, in addition to the above-mentioned estimation of the actual potential for consolidating and improving the carbon sequestration capacity of each land patch, in an embodiment of the present invention, the actual potential for consolidating and improving the carbon sequestration capacity of a preset area can also be calculated based on the actual potential for consolidating and improving the carbon sequestration capacity of each land patch, so as to monitor the potential for consolidating and improving the carbon sequestration capacity of the preset area.

[0085] For example, taking the preset area as the corresponding land area of the whole country as an example, the actual potential for consolidating and improving the national carbon sink capacity can be estimated, forming a "picture" of the actual potential for consolidating and improving the national carbon sink capacity.

[0086] Specifically, when calculating the actual potential for consolidating and improving the carbon sink capacity of a preset area, the ecosystem carbon sink of the preset area within a time period can be calculated based on the ecosystem carbon sink of each land patch, and the maximum value of the ecosystem carbon sink of the preset area within a time period can be calculated based on the maximum value of the ecosystem carbon sink of the land patch; then the difference between the maximum value of the ecosystem carbon sink of the preset area and the ecosystem carbon sink of the preset area is calculated, and the difference is determined as the actual potential for consolidating and improving the carbon sink capacity of the preset area within the time period.

[0087] Among them, the ecosystem carbon sink in the preset area is expressed as:

[0088]

[0089] Among them, m is the total number of land patches in the preset area, that is, the preset area covers multiple land patches, CS n Represents the ecosystem carbon sink in a preset area covering m land patches.

[0090] The maximum value of ecosystem carbon sink in the preset area is expressed as:

[0091]

[0092] Among them, MACS is the maximum value of ecosystem carbon sinks of a land patch within a time period; that is, the sum of the maximum values of ecosystem carbon sinks of all land patches covered by a preset area within a preset time period.

[0093] The actual potential for consolidation and improvement of carbon sequestration capacity in a given region within a time period is expressed as:

[0094] PCS=MACS-CS n .

[0095] Taking the preset area as the corresponding national territory area as an example, the above CS n It is the national ecosystem carbon sink covering all land patches in the current year; MACS is the maximum value of the national ecosystem carbon sink, and the corresponding PCS is the actual potential for consolidating and improving the national carbon sink capacity.

[0096] Therefore, in the embodiment of the present invention, based on the actual potential for consolidating and improving the carbon sequestration capacity of the above-mentioned preset regions within the time period, the actual potential for consolidating and improving the national carbon sequestration capacity can be estimated to form a "picture" of the actual potential for consolidating and improving the national carbon sequestration capacity.

[0097] Moreover, on this basis, in an embodiment of the present invention, it is possible to screen all county-level administrative regions across the country according to the ratio of the number of key patches with potential for consolidating and improving carbon sequestration capacity within the county-level administrative regions to the total number of land patches in the county-level administrative regions, and identify county-level administrative regions where the number of key patches with potential for consolidating and improving carbon sequestration capacity accounts for more than a certain ratio, such as more than 80%, of the total number of land patches as key counties with potential for consolidating and improving carbon sequestration capacity across the country, thereby providing a decision-making basis for setting targets for consolidating and improving carbon sequestration capacity and regulating carbon sequestration in ecosystems.

[0098] In summary, based on the method for estimating the potential for consolidating and improving carbon sequestration capacity for unified supervision provided by the embodiments of the present invention, the following solutions can be implemented:

[0099] (1) Based on the annual carbon dioxide absorption and fixation capacity of green plants through photosynthesis, a formula for estimating the actual potential of carbon sink capacity to be consolidated and improved for unified supervision is established;

[0100] (2) Collect data and information on the actual potential for consolidation and improvement of carbon sequestration capacity for unified supervision as basic data, and combine it with the national ecosystem carbon sequestration assessment with land patches as spatial units and years as temporal units to estimate the actual potential for consolidation and improvement of carbon sequestration capacity of all land patches in the country;

[0101] (3) Determine the criteria for delineating key areas with the potential for consolidating and improving carbon sink capacity, identify key areas with the potential for consolidating and improving carbon sink capacity, and delineate key areas with the potential for consolidating and improving carbon sink capacity that are subject to unified supervision.

[0102] Furthermore, the method for estimating the potential for consolidating and improving carbon sink capacity for unified supervision provided by the embodiment of the present invention, based on a thorough investigation of relevant research on the potential for consolidating and improving carbon sink capacity and an in-depth analysis of the deficiencies of the current estimation of the potential for consolidating and improving carbon sink capacity in the supervision of ecosystem carbon sinks, selects the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year as a measurement indicator of ecosystem carbon sinks, and establishes an estimation method for the actual potential for consolidating and improving carbon sink capacity for unified supervision; combined with the national ecosystem carbon sink assessment with land patches as spatial units and years as time units, the actual potential for consolidating and improving carbon sink capacity of all land patches is estimated, forming a comprehensive A "one-picture map" of the actual potential for consolidating and enhancing the country's carbon sink capacity; based on this, key patches with potential for consolidating and enhancing carbon sink capacity are identified, and key areas with potential for consolidating and enhancing carbon sink capacity subject to unified supervision are delineated; according to the proportion of key patches with potential for consolidating and enhancing carbon sink function to the total number of land patches, key counties with potential for consolidating and enhancing carbon sink capacity across the country are screened and determined, which provides an effective method for formulating goals for consolidating and enhancing carbon sink capacity, enhancing the effectiveness of ecological protection and restoration of carbon sinks, and establishing and implementing an ecosystem carbon sink supervision system aimed at spatial control and quality improvement. It also lays a solid foundation for ecological and environmental departments to accurately and efficiently perform their responsibilities for ecosystem carbon sink supervision.

[0103] In summary, the method for estimating the potential for consolidating and improving carbon sequestration capacity for unified supervision provided by the embodiments of the present invention has the following beneficial effects:

[0104] (1) Focusing on the annual ability of green plants to absorb and fix carbon dioxide through photosynthesis, we will conduct an estimation of the actual potential for consolidating and improving carbon sink capacity for unified supervision, clarify the actual potential for consolidating and improving carbon sink capacity and its key areas, and facilitate the ecological and environmental departments to implement unified, accurate, and efficient supervision of ecosystem carbon sinks;

[0105] (2) Taking land patches as spatial units, the spatial continuity of the estimation of carbon sink capacity consolidation and improvement potential is achieved, which is conducive to fully exploring the carbon sink capacity consolidation and improvement potential of all land patches and is conducive to avoiding duplication and omission problems in the estimation of carbon sink capacity consolidation and improvement potential based on various resource survey and monitoring data;

[0106] (3) Based on a “one map” of the actual potential for consolidating and improving carbon sink capacity covering all land patches, key patches with potential for consolidating and improving carbon sink capacity are identified, and key areas with potential for consolidating and improving carbon sink capacity for unified supervision are delineated, providing a scientific basis for establishing and implementing an ecosystem carbon sink supervision system with the goals of spatial control and quality improvement, and for scientifically formulating countermeasures and effective paths for consolidating and improving carbon sink capacity.

[0107] Furthermore, based on the above embodiment, the embodiment of the present invention also provides a device for estimating the potential for consolidation and improvement of carbon sink capacity for unified supervision, such as Figure 3 The schematic diagram of a structural diagram of a device for estimating the potential for consolidation and enhancement of carbon sequestration capacity for unified supervision is shown, and the device includes the following structures:
