[0002] In recent years, ecological and environmental accidents have occurred frequently, and the consequences of ecological and environmental damage are often very serious. The perpetrators who damage the ecological environment should repair and compensate for the ecological damage in the area involved, often by paying ecological restoration fees or paying ecological restoration costs. However, for a long time, the use of damages has become a difficult problem in practice. To this end, the "ecological justice + carbon sink" working mechanism is adopted to solve the period damage of forest resource destruction cases in ecological and environmental damage cases.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] The method for calculating and monitoring the alternative restoration of carbon sinks for ecological environmental damage provided in the embodiments of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be set up separately, or it can be integrated on the server 104, or it can be placed on the cloud or other servers. The terminal 102 can send the time-series remote sensing images of the ecologically damaged plots to the server 104, and the server 104 determines the project tree carbon sink loss, the project ecological value loss value and the carbon sink value based on the received time-series remote sensing images of the ecologically damaged plots. The server 104 can feedback the project tree carbon sink loss, the project ecological value loss value and the carbon sink value to the terminal 102. In addition, in some embodiments, the ecological environment damage carbon sink alternative restoration calculation and monitoring method can also be implemented by the server 104 or the terminal 102 alone.

[0035] The terminal 102 may be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers, or may be a cloud server.

[0036] In an exemplary embodiment, Figure 2 As shown, a method for calculating and monitoring alternative restoration of ecological environment damage carbon sinks is provided. The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the method is applied to Figure 1 The server 104 in the example is used for explanation, and the steps include the following steps 201 to 207.

[0037] Step 201, obtaining time-series remote sensing images of ecologically damaged land.

[0038] Step 202, determining the damaged area and the control area according to the time-series remote sensing images.

[0039] In an exemplary embodiment, step 202 includes steps 21 to 24 below.

[0040] Step 21, determine the damage start time and damage area according to the time series remote sensing images. Specifically, by comparing the time series remote sensing images, determine the damage start time, damage process and damage end time, and use commercial software or program to process the remote sensing images to obtain the damage area and even the scope.

[0041] The end time of damage mainly confirms whether there are other man-made or natural factors that cause changes in the on-site situation between the incident and the investigation period. If so, it should not be included in the scope of assessment.

[0042] Step 22, selecting the remote sensing image corresponding to the damage start time from the time series remote sensing images to obtain the image before the damage.

[0043] Step 23, determining a plurality of candidate plots according to the location of the ecologically damaged plot, and obtaining a remote sensing image of each candidate plot.

[0044] Step 24, determine the control area based on the remote sensing image of each candidate plot and the image before damage. Specifically, obtain the remote sensing image of the surrounding area of ​​the ecologically damaged plot, and then select the area closest to the forest conditions of the ecologically damaged plot as the control area based on the forest topography data, forest density, forest type and other data.

[0045] The number of the control area is one or more.

[0046] The forest type of the ecologically damaged land parcel is determined based on the pre-damage image.

[0047] If the forest type of the ecologically damaged plot is one, the remote sensing image of each candidate plot is measured for similarity with the image before damage, and the candidate plot with the highest similarity is used as a control area.

[0048] If the ecologically damaged plot has multiple forest types, the pre-damage image is divided into multiple damaged areas according to the forest types to obtain an image of each forest type.

[0049] For any forest type, the remote sensing image of each candidate plot is measured for similarity with the image of the forest type, and the candidate plot with the highest similarity is used as the control area of ​​the forest type to obtain multiple control areas, so as to calculate the carbon sequestration per unit area of ​​different forest types in subsequent blocks.

[0050] Step 203: determine the carbon sink per unit area of ​​the control area.

[0051] In an exemplary embodiment, step 203 includes the following steps 31 and 32 .

[0052] Step 31, conduct a field survey on the current status of the control area to determine the tree species data, tree height data and tree diameter at breast height data of the control area. Specifically, a sample plot survey is conducted on the control area to obtain data species data, tree height data and tree diameter at breast height data through field observation and measurement.

[0053] Step 32, calculating the carbon sink per unit area of ​​the control area according to the tree species data, tree height data and tree breast diameter data of the control area.

[0054] Specifically, the carbon sink per unit area of ​​the control area can be calculated through industry standards (such as the relevant formulas and parameter tables in the "Guidelines for Measuring Carbon Stocks in Forest Ecosystems (LY / T 2988-2018)").

[0055] Step 204, determining the carbon sink amount before damage of the ecologically damaged plot according to the carbon sink amount per unit area and the damaged area, wherein the carbon sink amount before damage = carbon sink amount per unit area * damaged area.

[0056] If there are multiple control areas determined in step 202, the carbon sink per unit area of ​​each control area is calculated in step 203, and the carbon sink before damage of each damaged area is calculated in step 204 according to the carbon sink per unit area of ​​each control area and the damaged area of ​​each forest type, and then the carbon sink before damage of all damaged areas is added together to obtain the carbon sink before damage of the ecologically damaged plot.

[0057] Step 205, calculating the total carbon sink of the compensation measures for the ecologically damaged plots according to the annual carbon absorption per unit area of ​​each type of replanted tree and the planting area of ​​each type of replanted tree in the ecologically damaged plots.

[0058] In an exemplary embodiment, step 205 includes the following steps 51 and 52 .

[0059] Step 51, for any type of replanted trees, calculate the product of the annual carbon absorption per unit area of ​​the replanted trees and the planting area of ​​the replanted trees to obtain the compensation measure carbon sink of the replanted trees.

[0060] Step 52, adding up the carbon sink amounts of the compensation measures for each type of replanted trees to obtain the carbon sink amounts of the compensation measures for the ecologically damaged land.

[0061] Among them, the types of trees to be replanted are generally required to be restored according to the number and variety of trees on the ecologically damaged plots before the damage, or to refer to the restoration assessment report plan for replanting. The time for replanting trees is determined according to the time of handling the case or the time of loss assessment. The carbon sequestration capacity of young forests is not as strong as that of middle-aged forests, and the ability of forests to absorb carbon dioxide during the restoration period is weak. The loss during the period refers to the loss of service functions of the ecological environment from the occurrence of damage to the completion of restoration.

[0062] Step 206, determining the carbon sink loss and carbon sink value of the project trees based on the carbon sink amount before the damage, the carbon sink amount of the compensation measures, the carbon emission rights trading price and the carbon sink price.

[0063] In an exemplary embodiment, step 206 includes the following steps 61 and 62 .

[0064] Step 61, calculate the difference between the carbon sink amount before the damage and the carbon sink amount of the compensation measure to obtain the carbon sink loss of the project trees. The carbon sink loss of the project trees can provide support for public interest litigation.

[0065] Step 62, calculating the carbon sink value according to the carbon sink loss of the project trees and the carbon sink price: carbon sink value = carbon sink loss of the project trees × carbon sink price.

[0066] Step 207, after replanting trees on the ecologically damaged plots, regularly monitor the restoration of the ecologically damaged plots, and recalculate the carbon sink loss and carbon sink value of the project trees based on the restoration status to comprehensively restore the ecologically damaged plots.

[0067] After replanting trees on ecologically damaged land, necessary management measures should be taken, such as seedling survival rate and maintenance responsibilities. However, many times the restoration effect does not meet expectations. To avoid this, this application further uses satellite remote sensing to understand the changes in carbon sinks in real time and formulate response measures in a timely manner. If the replanting effect is not good, the carbon sink loss of the project trees needs to be recalculated, and the infringer needs to purchase additional carbon sinks to achieve comprehensive restoration of the damaged ecology.

[0068] Satellite remote sensing can monitor the entire process of forest destruction with its advantages of continuous, stable and periodic observation, providing a new technical means for forest carbon sink calculation and monitoring. Satellite remote sensing data is used to monitor forest cover changes, determine the time of forest destruction, extract afforestation or felling areas, estimate forest carbon sinks, and calculate carbon sink changes, providing a new method for carbon sink compensation measurement and monitoring. When the damaged ecological environment does not meet the conditions for basic restoration or the restoration effect is poor, satellite remote sensing is used to calculate carbon sink losses to complete alternative restoration and monitor the effects of the restoration, that is, to compensate for the carbon sink losses from the time the ecological environment is damaged to the completion of restoration through voluntary purchase of carbon sinks, so as to achieve comprehensive restoration of the damaged ecology.

[0069] This application uses satellite remote sensing methods to carry out the measurement and monitoring of carbon sink compensation in alternative restoration responsibilities, and uses the significant advantages of satellite remote sensing methods to carry out the carbon sink situation of ecologically damaged plots before damage, and combines the current status survey of the control area to further judge the situation of the ecologically damaged plots before damage, calculate the carbon sink amount of the ecologically damaged plots, improve the reliability and credibility of the calculation results, and use satellite remote sensing to understand the changes in carbon sinks in real time, formulate response measures in a timely manner, and achieve comprehensive restoration of the damaged ecology.
