[0037] 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 below in conjunction with the accompanying drawings. 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] At present, judging from the progress of ecosystem carbon sink research, relevant technologies have carried out research on ecosystem carbon reserves, carbon fixation and oxygen release functions, carbon sink capacity, etc., and formed research methods such as sample site inventory method, model simulation method, and remote sensing estimation method.

[0039] However, current research on ecosystem carbon sinks generally focuses on a certain region or a certain type of ecosystem. Affected by factors such as data sources, research scales, research methods, differences in ecosystem types, and regional differences, there is great uncertainty in the research results related to ecosystem carbon sinks. There are also problems such as gaps or overlaps in the national ecosystem carbon sink assessment in space.

[0040] At the same time, current research on ecosystem carbon sinks mainly focuses on the assessment and accounting of ecosystem carbon reserves, carbon fixation and oxygen release functions, and the connection between research results and management decisions is relatively weak. There is a clear lack of attention paid to the research on ecosystem carbon sink regulation. The protection space of my country's high-value areas and degraded areas of ecosystem carbon sinks is still unclear, and the research on the evaluation of the effectiveness of national ecosystem carbon sink protection and restoration is still lagging behind.

[0041] Therefore, in view of the shortcomings in current research on ecosystem carbon sinks, especially in the evaluation of the effectiveness of ecosystem carbon sink protection and restoration, it is urgent to develop an evaluation method for the effectiveness of ecosystem carbon sink protection and restoration for unified supervision.

[0042] Based on this, an ecosystem carbon sink protection and restoration effectiveness assessment method for unified supervision provided in an embodiment of the present invention can effectively solve the above-mentioned technical problems, and further effectively assess the effectiveness of ecosystem carbon sink protection and restoration.

[0043] To facilitate understanding of this embodiment, a method for evaluating the effectiveness of ecosystem carbon sink protection and restoration for unified supervision disclosed in an embodiment of the present invention is first introduced in detail.

[0044] In a possible implementation, the present invention provides a method for evaluating the effectiveness of ecosystem carbon sink protection and restoration for unified supervision, such as Figure 1 The flowchart of a method for evaluating the effectiveness of ecosystem carbon sink protection and restoration for unified supervision is shown in FIG. 1 , and the method includes the following steps:

[0045] Step S102, obtaining ecosystem carbon sink data corresponding to a preset period in a preset area;

[0046] The preset area in the embodiment of the present invention covers multiple land patches, and the ecosystem carbon sink data includes the ecosystem carbon sink of each land patch within the preset time period;

[0047] Step S104, taking a preset area as an assessment area and a preset period as an assessment period, determining the ecosystem carbon sink of each land patch in the assessment period within the assessment period and the assessment base period corresponding to the assessment period based on the ecosystem carbon sink data, and the ecosystem carbon sink corresponding to the assessment area;

[0048] In actual use, the above-mentioned preset area can be the land area of ​​one or more administrative regions, or the land area of ​​the whole country, which shall be subject to the actual situation and is not limited in this embodiment of the present invention.

[0049] Generally, the assessment area and period can be determined based on the progress of implementation of relevant policies, plans, projects, etc. for ecological protection and restoration and the actual needs of the assessment.

[0050] Furthermore, the ecosystem carbon sink in the embodiment of the present invention refers to the ability of green plants to absorb carbon dioxide from the atmosphere through photosynthesis and fix it in the plant body or soil. The more organic matter the plant forms through photosynthesis, the greater the plant's net primary productivity, and the stronger the ecosystem carbon sink capacity; conversely, the weaker the ecosystem carbon sink capacity. Therefore, 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.

[0051] 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 measurement indicator of ecosystem carbon sink, which can avoid problems such as spatial discontinuity, duplication, and omissions in ecosystem carbon sink assessment caused by inconsistent time, cycle, and scope of various resource surveys and monitoring.

[0052] In addition, using the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year as a measurement indicator of ecosystem carbon sinks can also reflect the impact of factors such as climate, soil, topography, vegetation type, etc. on plant growth, development and ecosystem carbon sinks, and reflect the changing trends and regional differences in ecosystem carbon sink capacity, thereby meeting the needs of establishing an ecosystem carbon sink supervision system aimed at spatial control and quality improvement, and implementing monitoring and evaluation of the effectiveness of carbon sinks in ecological protection and restoration.

[0053] Furthermore, considering that the effectiveness of ecosystem carbon sink protection and restoration is the effect achieved by ecological protection and restoration-related policies, plans, and projects in ecosystem carbon sink protection and restoration, the above-mentioned assessment area can be determined based on the actual needs of the assessment of the effectiveness of ecosystem carbon sink protection and restoration.

[0054] Specifically, the assessment area in the embodiment of the present invention is also referred to as the assessment scope, which is the administrative region or ecological environment control zone where relevant policies, plans, and projects for ecological protection and restoration are implemented, such as national key ecological function zones, ecological protection red lines, nature reserves, and other important ecological function areas, as well as major ecological protection and restoration project implementation areas such as the integrated protection and restoration project of mountains, rivers, forests, farmlands, lakes, grasslands, and deserts.

[0055] In addition, the evaluation base period and evaluation period of the effectiveness of ecosystem carbon sink protection and restoration can also be determined based on the progress of the implementation of policies, plans, and projects related to ecological protection and restoration. Specifically, the evaluation base period in the embodiment of the present invention refers to the previous year or the base year of the implementation of policies, plans, and projects related to ecological protection and restoration in the evaluated area, which can be used as the initial time for comparison with various evaluation indicators in the evaluation period. The evaluation period is the time for conducting the evaluation of the effectiveness of ecosystem carbon sink protection and restoration, which usually includes multiple years.

[0056] Step S106, establishing an ecosystem carbon sink protection and restoration effectiveness evaluation system in the dimension of quality improvement based on the ecosystem carbon sink of each land patch during the evaluation period and the evaluation base period and the ecosystem carbon sink corresponding to the evaluation area;

[0057] Step S108, evaluating the effectiveness of ecosystem carbon sink protection and restoration in the assessment area based on the ecosystem carbon sink protection and restoration effectiveness assessment system in the quality improvement dimension.

[0058] In actual use, the ecosystem carbon sink protection and restoration effectiveness evaluation system in the quality improvement dimension established in the above-mentioned step S106 in the embodiment of the present invention evaluates the quality of the ecosystem carbon sink protection and restoration effectiveness. Specifically, in the embodiment of the present invention, the quality improvement dimension is quantified by the quality improvement rate. Therefore, in the above-mentioned step S106, when establishing the ecosystem carbon sink protection and restoration effectiveness evaluation system in the quality improvement dimension, the ecosystem carbon sink quality improvement rate of each land patch during the evaluation period and the ecosystem carbon sink quality improvement rate of the assessment area can be calculated based on the ecosystem carbon sink of each land patch during the evaluation period and the assessment base period and the ecosystem carbon sink corresponding to the assessment area.

[0059] Furthermore, when evaluating the effectiveness of ecosystem carbon sink protection and restoration in the above step S108, the effectiveness of ecosystem carbon sink protection and restoration of each land patch can be evaluated based on the ecosystem carbon sink quality improvement rate of each land patch, and the effectiveness of ecosystem carbon sink protection and restoration in the assessment area can be evaluated based on the ecosystem carbon sink quality improvement rate of the assessment area.

[0060] Therefore, an ecosystem carbon sink protection and restoration effectiveness assessment method for unified supervision provided by an embodiment of the present invention can obtain ecosystem carbon sink data corresponding to a preset time period in a preset area, and then take the preset area as the assessment area and the preset time period as the assessment period, determine the assessment period within the assessment period, the ecosystem carbon sink of each land patch within the assessment base period corresponding to the assessment period, and the ecosystem carbon sink corresponding to the assessment area based on the ecosystem carbon sink data; and establish an ecosystem carbon sink protection and restoration effectiveness assessment system in the quality improvement dimension based on the ecosystem carbon sink protection and restoration effectiveness assessment system in the quality improvement dimension; and then evaluate the ecosystem carbon sink protection and restoration effectiveness in the assessment area based on the ecosystem carbon sink protection and restoration effectiveness assessment system, which not only fills the gap in the current ecological restoration effectiveness assessment in terms of ecosystem carbon sink assessment, but also can effectively assess whether the ecosystem carbon sink protection space is effectively protected, as well as the protection and restoration effectiveness of various ecological protection and restoration policies, plans, and projects on ecosystem carbon sinks, so as to provide a scientific basis for formulating and implementing scientific, reasonable and targeted ecosystem carbon sink protection and restoration strategies, thereby improving the supervision level of ecosystem carbon sinks.

[0061] In actual use, in order to obtain the ecosystem carbon sink data in the above step S102, usually, relevant assessment data can be collected.

[0062] Specifically, data and information on the evaluation of the effectiveness of ecosystem carbon sink protection and restoration for unified supervision can be collected through data collection, field research, investigation and monitoring, mainly including ecosystem carbon sink assessment data and ecological protection and restoration policies, plans, and engineering related data.

[0063] Among them, ecosystem carbon sink assessment data include remote sensing images covering the whole country, image-derived data, and data on administrative divisions, ecosystem types, vegetation types, etc. Among them, remote sensing images and image-derived data covering the whole country include national plant net primary productivity (NPP) data, etc. Vegetation types come from vegetation maps in relevant research materials, and ecosystem type data can refer to the classification system of the national ecological status remote sensing survey and assessment ecosystem, which usually includes 8 types such as forests, shrubs, grasslands, wetlands, farmlands, towns, deserts and bare land. Administrative division data can use the national administrative division data set.

[0064] Furthermore, the above-mentioned ecological protection and restoration policies, plans, and engineering-related materials include vector boundary data of the assessment scope, as well as relevant materials such as the implementation content and implementation time of ecological protection and restoration policies, plans, and engineering projects. Among them, the assessment scope includes national key ecological function areas, ecological protection red lines, nature reserves and other ecological environment control zones, major ecological restoration project implementation areas such as the integrated protection and restoration project of mountains, rivers, forests, farmlands, lakes, grasslands, and deserts, and ecological protection and restoration planning implementation areas.

[0065] In addition, for the above collected data, a geographic information system (GIS) can also be used to pre-process the collected relevant data, such as data format conversion, projection conversion, resampling, spatial interpolation, etc. After pre-processing, various types of relevant data can be unified to the same coordinate system and the same image resolution to facilitate superposition and calculation in subsequent steps.

[0066] The specific data collection and data preprocessing process may refer to the relevant technologies and be based on the actual usage, and the embodiments of the present invention do not limit this.

[0067] Furthermore, considering that in the embodiment of the present invention, ecosystem carbon sinks are used as the basis for evaluating the effectiveness of restoration, in the embodiment of the present invention, the common mechanisms and fundamental mechanisms of carbon sinks in various ecosystems, as well as the influence of factors such as biomass and carbon storage conversion, plant loss, etc. are comprehensively considered to target the main deficiencies in the current ecosystem carbon sink assessment, the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year is selected as the measurement indicator, the ecosystem carbon sink is first constructed, and then the effectiveness of ecosystem carbon sink protection and restoration under unified supervision is further evaluated.

[0068] Specifically, for the above ecosystem carbon sink data, in the embodiment of the present invention, the following ecosystem carbon sink calculation formula is used as the basis for calculation and evaluation.

[0069] CS ij =MD ij ×S×∝

[0070] MD ij =γ×NPP ij

[0071]

[0072] In the formula, CS ij is the ecosystem carbon sink of land patch i in the jth year during the assessment period; S is the area of ​​the land patch; α is the coefficient of biomass conversion to carbon; MD ij is the aboveground biomass density of land patch i in the jth year; γ is the plant loss coefficient; NPP ij is the net primary productivity of plants in patch i in year j; CS j is the ecosystem carbon sink in the assessment area in the jth year, also known as the ecosystem carbon sink in the assessment area; n is the number of land patches in the assessment area.

[0073] Therefore, based on the above formula, the ecosystem carbon sink of each land patch in the assessment period within the assessment period, the assessment base period corresponding to the assessment period, and the ecosystem carbon sink corresponding to the assessment area can be calculated respectively.

[0074] In actual use, when evaluating and calculating the above ecosystem carbon sink data, ArcGIS spatial analysis-map algebra tools can be used for calculation, and other analysis tools can also be used, which depends on the actual use situation. The embodiment of the present invention does not limit this.

[0075] Further, after obtaining the ecosystem carbon sink of each land patch in the assessment period and the assessment base period corresponding to the assessment period, and the ecosystem carbon sink corresponding to the assessment area in the above step S104, when calculating the ecosystem carbon sink quality improvement rate of each land patch and the entire assessment area, the ecosystem carbon sink quality improvement rate of each land patch in the assessment period can be calculated according to the following formula:

[0076]

[0077] Where j is the year in the evaluation period; k is the year of the evaluation base period; m is the number of years in the evaluation period, and m = jk; R ij represents the improvement rate of ecosystem carbon sink quality of land patch i during the assessment period; CS ij , CS ik are the ecosystem carbon sinks of land patch i in year j and year k respectively;

[0078] And, the carbon sink quality improvement rate of the ecosystem in the assessment area is calculated according to the following formula:

[0079]

[0080] Among them, R j To evaluate the carbon sink quality improvement rate of regional ecosystems during the assessment period; CS j , CS k are the ecosystem carbon sinks in the assessment area in the jth year and the kth year, respectively.

[0081] In actual use, by analyzing the ecosystem carbon sink quality improvement rate Rj in the above-mentioned assessment area, the effectiveness of ecosystem carbon sink protection and restoration can be evaluated, and a scientific basis can be provided for optimizing the layout of ecological protection and restoration projects and strengthening the supervision of ecological protection and restoration.

[0082] Specifically, in the above step S108, when conducting the assessment, if the improvement rate of the ecosystem carbon sink quality in the assessment area is greater than the preset first improvement rate threshold, it is determined that the ecosystem carbon sink protection and restoration in the assessment area meets the preset results; if the improvement rate of the ecosystem carbon sink quality in the assessment area is not greater than the preset first improvement rate threshold, it is determined that the ecosystem carbon sink protection and restoration in the assessment area does not meet the preset results.

[0083] For example, taking the first improvement rate threshold set to 0 as an example, if the improvement rate of the ecosystem carbon sink quality in the assessment area is greater than 0, it means that the ecosystem carbon sink in the assessment area has increased during the assessment period, indicating that the ecological protection and restoration policies, plans or engineering implementation have achieved significant results.

[0084] On the contrary, if the assessment results show that the improvement rate of the ecosystem carbon sink quality in the assessment area is negative, that is, <0, it means that the ecosystem carbon sink in the assessment area has declined during the assessment period, and may have been adversely affected by human activities, natural disasters, climate change, etc., resulting in a decline in the ecosystem carbon sink. This requires the relevant departments to pay close attention, strengthen the monitoring and assessment of the ecosystem carbon sink, optimize the ecological protection and restoration strategies, and consolidate and enhance the ecosystem carbon sink.

[0085] Furthermore, similar to the above-mentioned assessment of the regional ecosystem carbon sink quality improvement rate Rj, if the ecosystem carbon sink quality improvement rate of the land patch is greater than the preset second improvement rate threshold, then it is determined that the ecosystem carbon sink protection and restoration of the land patch meets the preset results; if the ecosystem carbon sink quality improvement rate of the land patch is not greater than the preset second improvement rate threshold, then it is determined that the ecosystem carbon sink protection and restoration of the land patch does not meet the preset results.

[0086] Similarly, the second improvement rate threshold is 0 for explanation. The improvement rate of ecosystem carbon sink quality R of each land patch in the assessment area ijRepresents the protection and restoration effect of ecosystem carbon sinks in each land patch. The higher the improvement rate of ecosystem carbon sink quality in the land patch, the higher the protection and restoration effect of ecosystem carbon sink; conversely, areas where the improvement rate of ecosystem carbon sink quality in the land patch is less than 0 need to increase the intensity of ecological protection and restoration.

[0087] At the same time, by conducting detailed analysis of the ecosystem carbon sink quality improvement rate of each land patch, such as comparing the ecosystem carbon sink quality improvement rate of different land patches, we can more accurately identify areas that have achieved remarkable results in ecosystem carbon sink protection and restoration and areas facing challenges, thereby providing a scientific basis for the subsequent formulation of more targeted and differentiated ecological protection and restoration strategies, helping to promote the optimal allocation and sustainable utilization of ecological protection and restoration resources, and improving the effectiveness of ecological protection and restoration and the level of ecosystem carbon sink supervision.

[0088] Therefore, the above-mentioned process of evaluating the effectiveness of ecosystem carbon sink protection and restoration based on the ecosystem carbon sink quality improvement rate in the embodiment of the present invention is actually a method for evaluating the effectiveness of ecosystem carbon sink protection and restoration in the quality improvement dimension.

[0089] Furthermore, in addition to the above-mentioned quality improvement dimension for evaluating the effectiveness of ecosystem carbon sink protection and restoration, in the embodiments of the present invention, a spatial control dimension for evaluating the effectiveness of ecosystem carbon sink protection and restoration is also established.

[0090] Specifically, in Figure 1 On the basis of Figure 2 It also shows a flow chart of another method for evaluating the effectiveness of ecosystem carbon sink protection and restoration for unified supervision, further explaining the process of establishing an ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension and evaluating the effectiveness of ecosystem carbon sink protection and restoration.

[0091] Specifically, Figure 2 As shown, the following steps are included:

[0092] Step S202, obtaining ecosystem carbon sink data corresponding to a preset period in a preset area;

[0093] Step S204, taking the preset area as the assessment area and the preset period as the assessment period, based on the ecosystem carbon sink data, determining the ecosystem carbon sink of each land patch in the assessment period within the assessment period, the assessment base period corresponding to the assessment period, and the ecosystem carbon sink corresponding to the assessment area;

[0094] Step S206, calculating the ecosystem carbon sink quality improvement rate of each territorial patch during the assessment period and the ecosystem carbon sink quality improvement rate of the assessment area according to the ecosystem carbon sink of each territorial patch during the assessment period and the assessment base period and the ecosystem carbon sink corresponding to the assessment area;

[0095] Step S208, evaluating the effectiveness of ecosystem carbon sink protection and restoration of each territorial patch based on the ecosystem carbon sink quality improvement rate of each territorial patch, and evaluating the effectiveness of ecosystem carbon sink restoration and protection in the assessment area based on the ecosystem carbon sink quality improvement rate of the assessment area;

[0096] Among them, the process of step S204 to step S208 is the process of constructing the ecosystem carbon sink protection and restoration effectiveness evaluation system in the quality improvement dimension mentioned above, and can refer to the process of step S102 to step S108 mentioned above, which will not be repeated here.

[0097] Step S210, determining the average ecosystem carbon sink of each territorial patch during the assessment period based on the ecosystem carbon sink data, and the ecosystem carbon sink of each territorial patch each year during the assessment period;

[0098] Step S212, identifying the average ecosystem carbon sink value of each land patch according to the pre-configured ecosystem carbon sink high value area demarcation standard, and obtaining the ecosystem carbon sink high value patch;

[0099] Step S214, identifying the ecosystem carbon sink of each land patch in each year during the assessment period according to the pre-configured ecosystem carbon sink degradation area delineation standard, and obtaining the ecosystem carbon sink degradation patch;

[0100] Step S216, respectively aggregating high-value patches and degraded patches to obtain high-value areas and degraded areas of ecosystem carbon sinks;

[0101] Step S218, taking high-value areas and degraded areas as the ecosystem carbon sink protection space, and land patches as the basic units, establish an ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension, and evaluate the ecosystem carbon sink protection and restoration effectiveness in the evaluation area with the ecosystem carbon sink protection and restoration effectiveness evaluation system based on the spatial control dimension.

[0102] In actual use, the ecosystem carbon sink protection and restoration effectiveness evaluation system based on the spatial control dimension established in the embodiment of the present invention, as well as the evaluation process of the ecosystem carbon sink protection and restoration effectiveness based on the spatial control dimension, the evaluation area or evaluation scope usually refers to the national scope, or the scope of at least one administrative region. By superimposing the ecosystem carbon sink protection space in the whole country or administrative region with the ecological environment control zones such as the national key ecological functional areas, ecological protection red lines, nature reserves, and major ecological restoration project implementation areas, it can be judged whether the ecosystem carbon sink protection space in the whole country or administrative region is protected, which can provide a decision-making basis for adjusting and improving the existing ecological protection and restoration strategies.

[0103] In specific implementation, in the above step S210, when determining the average ecosystem carbon sink of each land patch during the assessment period, as well as the ecosystem carbon sink of each land patch each year during the assessment period, the land patch can be used as the spatial unit, the assessment period or the year of the assessment period can be used as the time unit, and based on the above-mentioned ecosystem carbon sink calculation formula, the ArcGIS Spatial Analysis-Map Algebra tool can be used to calculate the ecosystem carbon sink of each land patch during the assessment time.

[0104] Furthermore, the regional analysis tool can be used to further calculate the average value of the ecosystem carbon sink of all land patches in the assessment area (such as the national area) during the assessment period as a criterion for delineating high-value ecosystem carbon sink areas, and to calculate the average value of the ecosystem carbon sink of each land patch over many years during the assessment period as a criterion for delineating ecosystem carbon sink degradation areas, so as to identify and screen the land patches in steps S212 and S214.

[0105] The calculation formula of the above demarcation standard is expressed as:

[0106]

[0107]

[0108] Taking the national area as an example, in the above formula, HCS is the standard for defining high-value ecosystem carbon sink areas; m is the number of years in the assessment period; n is the number of land patches in the country; DCS i Criteria for delineating ecosystem carbon sink degradation areas; CS i It is the multi-year average of the ecosystem carbon sink of the ith land patch during the assessment period.

[0109] Specifically, in step S212, when dividing the ecosystem carbon sink high value patches, ArcGIS spatial analysis tools can usually be used to identify CS i>HCS land patches, as patches with high ecosystem carbon sinks, have ecosystem carbon sinks higher than the national average and should be given priority protection.

[0110] Furthermore, ArcGIS spatial analysis tools can be used to identify CS ij <DCS i The land patches are ecosystem carbon sink degradation patches, and the ecosystem carbon sink of such patches is lower than its multi-year average level, and should be repaired as a priority. Then in step S216, the ecosystem carbon sink high-value patches and degraded patches are aggregated respectively to obtain the ecosystem carbon sink high-value area and degraded area, and then establish the ecosystem carbon sink protection space.

[0111] Further, in the embodiment of the present invention, based on the above ecosystem carbon sink protection space, when establishing an ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial management dimension, the following process is generally included:

[0112] (1) Screening each territorial patch based on the ecosystem carbon sink protection space, and marking each territorial patch after screening with a first number;

[0113] Among them, the first number is used to characterize whether the land patch is located in the ecosystem carbon sink protection space; for example, based on the geographical location of the land patch, it can be determined whether the land patch belongs to the above-mentioned high-value area or degraded area. If so, the first number is marked for the land patch; if not, the "no number" corresponding to the first number is marked.

[0114] (2) Screening each land patch according to the pre-marked ecological environment control and restoration area, and marking each land patch after screening with a second number;

[0115] The second number in the embodiment of the present invention is used to indicate whether the land patch belongs to a pre-marked ecological environment control and restoration area;

[0116] Specifically, the ecological environment control and restoration area in the embodiment of the present invention actually refers to the ecological environment control zone or the implementation area of ​​a major ecological restoration project. It can also be screened based on the geographical location of the land patch. If the land patch is located in the above-mentioned area, the second number is marked for the land patch. If not, the "no number" corresponding to the second number is marked.

[0117] (3) Superimpose the first number and the second number to obtain the ecosystem carbon sink protection and restoration effectiveness number corresponding to each land patch in the assessment area;

[0118] Among them, the ecosystem carbon sink protection and restoration performance number includes effective restoration number, key restoration number and adjustment number;

[0119] (4) Based on the first number, second number and ecosystem carbon sink protection and restoration effectiveness number of each land patch, an ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension corresponding to the evaluation area is established.

[0120] In actual use, the ecosystem carbon sink protection and restoration effectiveness evaluation system in the above-mentioned spatial control dimension is mostly based on the national or administrative region as the evaluation scope, with ecosystem carbon sink protection spaces such as high-value areas and degraded areas of ecosystem carbon sinks as the basis, and land patches as the basic units. The ArcGIS spatial analysis-map algebra tool is used to overlay and analyze the high-value areas and degraded areas of ecosystem carbon sinks with national key ecological functional areas, ecological protection red lines, nature reserves and other ecological environmental control zones or major ecological restoration project implementation areas, and then construct the ecosystem carbon sink protection and restoration effectiveness evaluation system in the above-mentioned spatial control dimension based on the analysis results.

[0121] For ease of understanding, the following Table 1 shows a table of value assignment numbers for an ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension. As shown in Table 1, for each land patch, there can be the following types of value assignment numbers:

[0122] Table 1:

[0123]

[0124] Among them, the first column represents the number of ecosystem carbon sink protection and restoration results, the second column is the first number obtained by screening each land patch based on the ecosystem carbon sink protection space, and the third column is the second number obtained by screening each land patch based on the ecological environment control and restoration area;

[0125] That is, in the above Table 1, the first number and the second number are directly represented by "yes" and "no". It should be understood that in other implementations, other marks can also be used to record the first number, the second number and the ecosystem carbon sink protection and restoration effectiveness number. The specific settings can be made according to actual usage, and the embodiments of the present invention are not limited to this.

[0126] Furthermore, based on Table 1 above, from the perspective of land patches, by classifying and analyzing the ecosystem carbon sink protection and restoration effectiveness numbers of land patches, it is possible to identify areas within the assessment scope where the ecosystem carbon sink protection space is effectively protected and restored, areas where there are gaps in protection and restoration, and areas where there is excessive protection and restoration.

[0127] For example, if the first number and the second number of a land patch are both "yes", then the ecosystem carbon sink protection and restoration effectiveness number of the land patch is 1, that is, the effective restoration number, indicating that the area is a key target for ecosystem carbon sink supervision and ecological protection and restoration, and is located in the ecological environment control zone or the implementation area of ​​a major ecological restoration project, indicating that the ecosystem carbon sink in the area has been effectively protected and restored.

[0128] If the first number of a land patch is "yes" and the second number is "no", then the ecosystem carbon sink protection and restoration effectiveness number of the land patch is 2, that is, the key restoration number, indicating that the area is a key target for ecosystem carbon sink supervision and ecological protection and restoration, but due to various reasons such as funding shortages or technical bottlenecks, it has not yet enjoyed sufficient ecological protection and restoration measures. These areas often face the risk of ecosystem degradation and urgently need to fill the gaps in ecological protection and restoration. They are the key targets for future ecosystem carbon sink supervision and ecological protection and restoration.

[0129] If the first number of the land patch is "No" and the second number is "Yes", the ecosystem carbon sink protection and restoration effect number of the land patch is 3, that is, the adjustment number, indicating that the area does not belong to the ecosystem carbon sink protection space, but has obtained the tilt of ecological protection and restoration resources, which may be due to the inaccuracy of policy engineering planning or the imbalance of resource allocation, which may affect the efficiency and effectiveness of the overall ecological protection and restoration work. Therefore, for such areas, in-depth evaluation and adjustment are needed to ensure that ecological protection and restoration resources can be more reasonably and efficiently allocated to key ecological areas to avoid unnecessary waste and losses.

[0130] In addition, if the first number is "No" and the second number is "No", the ecosystem carbon sink protection and restoration effectiveness number of the land patch is 3, which means that this type of area neither belongs to the ecosystem carbon sink protection space nor has enjoyed sufficient ecological protection and restoration measures. The specific needs need to be evaluated and further analysis is needed.

[0131] Further, referring to Table 1 above, when evaluating the effectiveness of ecosystem carbon sink protection and restoration in the assessment area based on the ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension, the number of land patches corresponding to each ecosystem carbon sink protection and restoration effectiveness number can be counted according to the ecosystem carbon sink protection and restoration effectiveness evaluation system in the spatial control dimension; and then the ecosystem carbon sink protection and restoration effectiveness in the assessment area can be evaluated based on the number of land patches corresponding to each ecosystem carbon sink protection and restoration effectiveness number.

[0132] Specifically, based on the number of land patches corresponding to the effectiveness number of each ecosystem carbon sink protection and restoration, the first proportion of areas where the ecosystem carbon sink protection space in the assessment area has been restored, the second proportion of areas where there are restoration gaps in the ecosystem carbon sink protection space, and the third proportion of the ecosystem carbon sink protection space in the pre-marked ecological environment control and restoration area can be calculated, and then the effectiveness of ecosystem carbon sink protection and restoration in the assessment area can be evaluated based on the first proportion, the second proportion, and the third proportion.

[0133] Specifically, the first ratio is expressed as:

[0134]

[0135] The second ratio mentioned above is expressed as:

[0136]

[0137] The third ratio is expressed as:

[0138]

[0139] Among them, n1, n2, and n3 are the number of land patches with effective restoration numbers, key restoration numbers, and adjustment numbers in the assessment area, respectively.

[0140] For example, referring to Table 1, the above n1, n2, and n3 are the number of land patches numbered 1, 2, and 3 within the assessment scope, with the first column representing the effectiveness of ecosystem carbon sink protection and restoration.

[0141] In actual use, the above P1 represents the first proportion, that is, the proportion of areas within the assessment scope where ecosystem carbon sink protection space has been protected and restored; the above P2 represents the second proportion, that is, the proportion of areas within the assessment scope where there are gaps in protection and restoration of ecosystem carbon sink protection space; the above P3 represents the third proportion, that is, the proportion of ecosystem carbon sink protection space within the ecological environment control zone or the implementation area of ​​major ecological restoration projects.

[0142] Generally, when evaluating the effectiveness of ecosystem carbon sink protection and restoration in the assessment area based on the above-mentioned first ratio, second ratio, and third ratio, the higher the value of P1, the more targeted the ecosystem carbon sink protection and restoration in the assessment area. P2 indicates the proportion of ecosystem carbon sink space that has not been effectively protected and restored within the assessment scope. Therefore, a high P2 means that the current coverage of ecological protection and restoration in the region is still insufficient, or that the implemented protection and restoration measures have failed to fully cover all key areas. It is necessary to increase ecological protection and restoration efforts in these areas and optimize ecological protection and restoration strategies. P3 is the proportion of ecosystem carbon sink protection space in the protected and restored area. If P3 is high, it means that the ecological environment control zoning or major ecological restoration projects have a positive protective effect on ecosystem carbon sinks, reflecting scientific planning and effective management.

[0143] In actual use, the effectiveness of ecosystem carbon sink protection and restoration in the assessment area can be effectively quantitatively evaluated by reasonably setting the ratio thresholds of the above-mentioned first ratio, second ratio, and third ratio. The specific ratio thresholds can be set according to actual usage, and the embodiments of the present invention do not limit this.

[0144] In summary, the method for evaluating the effectiveness of ecosystem carbon sink protection and restoration for unified supervision provided in the embodiments of the present invention scientifically determines the evaluation scope and evaluation period based on a comprehensive investigation of relevant research on the effectiveness of ecosystem carbon sink protection and restoration at home and abroad and an in-depth analysis of the shortcomings of the current effectiveness of ecosystem carbon sink protection and restoration evaluation in supporting ecosystem carbon sink supervision; collects basic data related to the effectiveness of ecosystem carbon sink protection and restoration, and pre-processes the data; selects the amount of carbon dioxide absorbed and fixed by green plants through photosynthesis each year as a measurement indicator of ecosystem carbon sinks, constructs an ecosystem carbon sink evaluation method formula, and establishes an ecosystem carbon sink protection and restoration effectiveness evaluation method in the quality improvement dimension; delineates ecosystem carbon sink protection space, and establishes an ecosystem carbon sink protection and restoration effectiveness evaluation method in the spatial control dimension, which provides important scientific basis for optimizing the layout of ecological protection and restoration projects and establishing an ecosystem carbon sink supervision system with spatial control and quality improvement as the goals, and lays a solid foundation for the ecological environment department to uniformly exercise ecosystem carbon sink supervision and administrative law enforcement responsibilities.
