[0022] The overall idea of ​​the problem in the embodiment of this application is as follows:

[0023] First, when the mine ecology is being restored, ecological restoration data are obtained after each restoration stage of the mine to be evaluated, including geological environment data, water quality environment data, and plant environment data; then, data analysis is performed on the ecological restoration data after each restoration stage of the mine to be evaluated, and the geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators after each restoration stage of the mine to be evaluated are obtained.

[0024] See also Figure 1The embodiment of the present invention provides a technical solution: an environmental assessment method based on mine ecological restoration, comprising the following steps: when the mine ecology is being restored, ecological restoration data is obtained after each restoration stage of the mine to be evaluated, and the ecological restoration data includes geological environment data, water quality environment data, and plant environment data; and the ecological restoration data after each restoration stage of the mine to be evaluated are analyzed separately to obtain geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators after each restoration stage of the mine to be evaluated, and a comprehensive analysis is performed to obtain the comprehensive environmental restoration indicators after each restoration stage of the mine to be evaluated. Restoration evaluation index; compare and analyze the comprehensive environmental restoration evaluation index after each restoration stage of the restoration mine to be evaluated with the preset comprehensive environmental restoration evaluation index threshold; if the comprehensive environmental restoration evaluation index after each restoration stage of the restoration mine to be evaluated is higher than the preset comprehensive environmental restoration evaluation index threshold, no restoration and remediation measures will be taken; if the comprehensive environmental restoration evaluation index after each restoration stage of the restoration mine to be evaluated is lower than or equal to the preset comprehensive environmental restoration evaluation index threshold, identify abnormal evaluation indicators and take corresponding restoration and remediation measures; the formula for calculating the comprehensive environmental restoration evaluation index after each restoration stage of the restoration mine to be evaluated is as follows:

[0025]

[0026] Among them, HjP i DzH is the comprehensive environmental restoration evaluation index after the completion of the i-th restoration stage of the mine to be evaluated. i is the geological environment restoration evaluation index after the completion of the i-th restoration stage of the mine to be evaluated, α i1 is the geological coefficient after the end of the i-th restoration stage stored in the database, SzH i is the water quality environment restoration evaluation index after the i-th restoration stage of the mine to be evaluated, α i2 is the water quality coefficient after the i-th restoration stage stored in the database, SwH i is the plant environment restoration evaluation index after the i-th restoration stage of the mine to be evaluated, α i3 is the plant coefficient after the end of the i-th restoration stage stored in the database, α i1 +α i2 +α i3 =1,i=1,2,3,…,i 0 ,i 0 is the number of repair stages, e is a natural constant and its value is 2.71 in this implementation example.

[0027] It needs to be explained that α i1 , αi2 , α i3 The specific acquisition process is: read the geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators after each restoration stage of the restoration mine to be evaluated (it should be noted that the geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators are all dimensionless values, so they can be directly calculated), perform sum analysis, and obtain the comprehensive evaluation value after each restoration stage, and perform proportion analysis on the geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators of the restoration area of ​​the mine to be evaluated and the comprehensive evaluation value after the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0028] The geological environment data include the soil surface charge density value, soil moisture conductivity value, soil porosity value, soil organic matter content value, soil pollutant content value, soil thermal conductivity value and the activity value of each soil microorganism at each geological measurement point. The water quality environment data include the water transmittance value, water viscosity value, water nutrient concentration value, water dissolved gas partial pressure value, water hazardous substance concentration value, water optical density value, water surface tension value at each water quality measurement point. The plant environment data include the vegetation coverage value, plant chlorophyll content value, plant root density value, plant root depth value, and plant root respiration rate value of each restoration area.

[0029] Among them, the soil surface charge density value is the amount of charge carried on the surface of soil particles within the monitoring point. The higher the surface charge density, the stronger the adsorption capacity of the soil. High surface charge density means that the soil can adsorb more pollutants and nutrients. The soil surface charge density value can be obtained through sampling method, that is, using a certain concentration of calcium salt solution (such as calcium chloride) to soak the soil sample, and exchange the negative charge on the soil surface through ion exchange to exchange the exchangeable cations in the soil, and use a flame photometer to measure the concentration of calcium ions exchanged in the soil, that is, the ion exchange capacity, which is also the surface charge density value of the soil.

[0030] The soil moisture conductivity value is the water flow capacity in the soil. When the moisture conductivity value is high, pollutants will be carried away with the rapid movement of water, reducing the adsorption capacity of the soil. The soil moisture conductivity value can be obtained through the sampling method, that is, using a vertical pipe to inject water into the soil sample, ensuring a constant water head, maintaining a constant water level, and allowing water to penetrate through the soil, recording the amount of water flowing through the soil per unit time, then the soil moisture conductivity value = (amount of water penetrating the soil * thickness of the soil sample) / (height of the water head * cross-sectional area of ​​the soil sample).

[0031] The soil porosity value is the ratio of the void volume in the soil to the total volume of the soil, and the soil porosity value can be obtained by the sampling method, that is, taking a certain amount of soil sample, weighing it after drying to obtain the dry weight, soaking the soil sample in water to ensure complete saturation, then taking it out and weighing it to obtain the wet weight, then the soil porosity value = (wet weight-dry weight) / wet weight.

[0032] The soil organic matter content is the sum of all organic matter in the soil, including humus, plant residues, animal remains, etc. The higher the soil organic matter content, the greater the soil remediation potential, because it helps to restore the soil structure and stabilize pollutants. The soil organic matter content can be obtained through the sampling method, that is, the soil sample is weighed, heated (heated to 550°C), and the remaining soil sample mass is weighed. Then the soil organic matter content = soil sample mass - soil sample mass after heating treatment.

[0033] The soil pollutant content value is the sum of the concentrations of harmful substances (such as heavy metals) in the soil. The heavy metal content value can be measured by a portable heavy metal analyzer, and the measurement results can be uploaded to the database.

[0034] The thermal conductivity of soil is the ability of soil to transfer heat. When the thermal conductivity of soil is low, the temperature fluctuation of the soil surface is small, which provides a more stable environment for the survival and activity of micro-plants, thereby promoting the degradation of organic matter and the improvement of soil quality. The thermal conductivity of soil can be measured by a portable thermal conductivity meter, and the measurement results can be uploaded to the database.

[0035] The soil micro-plant activity value refers to the metabolic activity of the micro-plants in the soil. Highly active micro-plant communities can quickly decompose organic matter and pollutants in the soil, thereby accelerating the soil remediation process. The soil micro-plant activity value can be obtained through the sampling method, that is, using a carbon dioxide concentration sensor to measure the carbon dioxide release of the soil sample and upload the measurement results to the database.

[0036] The water body transmittance value is the ability of light to penetrate the water body. Plants in surface water (such as aquatic plants and phytoplankton) rely on photosynthesis to consume nutrients (such as nitrogen and phosphorus) and generate oxygen. The higher the transmittance, the stronger the photosynthesis, and the better the self-purification ability of the water body. The water body transmittance value can be obtained through a transmittance sensor.

[0037] The viscosity of water is the internal friction of water, that is, the resistance to water flow. The lower the viscosity, the stronger the fluidity of the water. Pollutants in the water can be diluted faster, gas exchange is more effective, and the self-purification of the water is promoted. The viscosity of water can be measured by a rotational viscometer and the measurement results can be uploaded to the database.

[0038] The nutrient concentration value of water bodies is the sum of the concentrations of compounds of nitrogen, phosphorus and other elements in the water body (nitrogen compounds: such as ammonia, nitrate, nitrite, etc., phosphorus compounds: such as phosphate, etc.), and the appropriate nutrient concentration value of water bodies supports the growth of aquatic plants, promotes the balance of natural ecosystems, and promotes the self-purification of water bodies. The concentration value of each compound can be measured by a water quality analyzer, and the measurement results can be uploaded to the database.

[0039] The dissolved gas partial pressure value of water is the solubility degree of dissolved gas (such as oxygen and carbon dioxide) in the water. A higher dissolved oxygen partial pressure means that the water can more effectively degrade organic pollutants and promote self-purification. The solubility degree of each dissolved gas can be obtained through a dissolved oxygen sensor.

[0040] The concentration of hazardous substances in water bodies is the sum of the concentrations of heavy metals (such as lead, mercury, arsenic, copper, etc.), organic pollutants (such as pesticides, solvents, petroleum substances, etc.) and other toxic chemicals in water bodies.

[0041] The optical density of water is a measure of the degree of absorption and scattering of light of a specific wavelength by suspended matter in the water. The higher the optical density of water, the more particulate matter is suspended in the water, which means increased water pollution. The optical density of water can be measured by a portable photometer and the measurement results can be uploaded to a database.

[0042] The surface tension of water is the force generated by the mutual attraction of molecules on the water surface. Pollutants (such as surfactants and oil substances) acting on the surface of water will reduce the surface tension of water, thereby promoting the diffusion and deposition of harmful substances, further aggravating the degree of water pollution. The surface tension of water can be measured by a portable surface tension meter, and the measurement results can be uploaded to the database.

[0043] The plant root density value is the number of plant roots in the restoration area, which can be obtained through the sampling method, that is, selecting soil samples of a certain depth and area from the restoration area, digging and cleaning the roots in the soil, counting the number of plant roots, and thus obtaining the root density, and uploading the results to the database.

[0044] The plant root depth value is the deepest level of plant root growth, that is, the vertical distribution depth of the plant root system in the soil. The plant root depth value can be obtained through random sampling method, that is, randomly selecting multiple plants and measuring them using a root scanner, and averaging the measurement results, and uploading the final results to the database.

[0045] The plant root respiration rate value is the rate of oxygen consumption and carbon dioxide release during plant respiration activities, and the plant root respiration rate value can be obtained through a random sampling method, that is, randomly selecting multiple plants and measuring them using a portable gas analyzer, and averaging the measurement results, and uploading the final results to the database.

[0046] Specifically, Figure 2 As shown, the specific steps for obtaining the geological environment restoration evaluation index after each restoration stage of the restoration mine to be evaluated are as follows: the soil surface charge density value, soil moisture conductivity value, soil porosity value, soil organic matter content value, soil pollutant content value, soil thermal conductivity value and the activity value of each soil microorganism at each geological measurement point after each restoration stage of the restoration mine to be evaluated are standardized (i.e., de-unitized); the soil surface charge density value, soil moisture conductivity value and soil porosity value of each geological measurement point after each restoration stage of the restoration mine to be evaluated after the standardized treatment are comprehensively analyzed to obtain the soil adsorption evaluation index after each restoration stage of the restoration mine to be evaluated; and the soil organic matter content value, soil pollutant content value, soil thermal conductivity value and the activity value of each soil microorganism at each geological measurement point after each restoration stage of the restoration mine to be evaluated after the standardized treatment are comprehensively analyzed to obtain the soil restoration evaluation index after each restoration stage of the restoration mine to be evaluated; the soil adsorption evaluation index and soil restoration evaluation index after each restoration stage of the restoration mine to be evaluated are comprehensively analyzed to obtain the geological environment restoration evaluation index after each restoration stage of the restoration mine to be evaluated.

[0047] The formulas for calculating the soil adsorption evaluation index, soil recovery evaluation index, and geological environment restoration evaluation index after each restoration stage of the mine to be evaluated and restored are as follows:

[0048]

[0049] Among them, QrX i is the soil adsorption evaluation index after the completion of the i-th restoration stage of the mine to be evaluated, QbD′ it is the soil surface charge density value of the t-th geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after standardization, δ i1 is the density coefficient after the i-th repair stage stored in the database, ScD i ' t is the soil moisture conductivity value of the t-th geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after the standardized treatment, δ i2 is the conduction coefficient after the end of the i-th repair stage stored in the database, QkD′ it is the soil porosity value of the t-th geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after the standardized treatment, δ i3 is the porosity coefficient after the i-th repair stage stored in the database, δ i1 +δ i2 +δi3 =1,QhF i is the soil restoration evaluation index after the completion of the i-th restoration stage of the mine to be evaluated, QyH′ it is the soil organic matter content value of the t-th geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after standardization, φ i1 is the organic coefficient after the end of the i-th restoration stage stored in the database, QwH′ it is the soil pollutant content value of the t-th geological measurement point after the completion of the ith restoration stage of the mine to be evaluated after standardization, φ 2 is the pollution coefficient after the end of the i-th repair stage stored in the database, QrD′ it is the soil thermal conductivity value of the t-th geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after the standardized treatment, φ i3 is the thermal conductivity after the i-th repair stage stored in the database, WsH′ itm is the activity value of the mth soil micro-plant at the tth geological measurement point after the completion of the ith restoration stage of the assessed restoration mine after standardized processing, φ i4 is the activity coefficient after the end of the i-th repair stage stored in the database, φ i1 +φ i2 +φ i3 +φ i4 =1, DzH is the geological environment restoration evaluation index after the completion of the i-th restoration stage of the mine to be evaluated, η i1 is the adsorption coefficient after the end of the i-th repair stage stored in the database, η i2 is the recovery coefficient after the i-th repair stage stored in the database, η i1 +η i2 =1,i=1,2,3,…,i 0 ,i 0 is the number of repair stages, t = 1, 2, 3, ..., t 0 , t 0 is the number of geological measurement points, m = 1, 2, 3, ..., m 0 , m 0 is the number of soil micro-plant species.

[0050] It needs to be explained that δ i1 , δ i2 , δ i3The specific acquisition process is as follows: read the soil surface charge density value, soil moisture conductivity value, and soil porosity value of each geological measurement point after each restoration stage of the mine to be evaluated after standardized processing, perform mean analysis, and obtain the mean value of soil surface charge density, soil moisture conductivity, and soil porosity after each restoration stage of the mine to be evaluated after standardized processing, and perform sum analysis to obtain the adsorption and value after each restoration stage, and perform proportion analysis on the mean value of soil surface charge density, soil moisture conductivity, and soil porosity after each restoration stage of the mine to be evaluated after standardized processing and the adsorption and value after the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0051] φ i1 ,φ i2 ,φ i3 ,φ i4 The specific acquisition process is as follows: read the soil organic matter content value, soil pollutant content value, soil thermal conductivity value and the activity value of each soil microorganism at each geological measurement point after each restoration stage of the mine to be evaluated after standardized treatment, perform mean analysis, and obtain the mean value of soil organic matter content, soil pollutant content, soil thermal conductivity and the activity value of each soil microorganism after each restoration stage of the mine to be evaluated after standardized treatment, and perform sum analysis to obtain the recovery sum value after each restoration stage, and perform proportion analysis on the mean value of soil organic matter content, soil pollutant content, soil thermal conductivity and the activity value of each soil microorganism after each restoration stage of the mine to be evaluated after standardized treatment and the recovery sum value after the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0052] η i1 , η i2 The specific acquisition process is: read the soil adsorption evaluation index and soil recovery evaluation index after each restoration stage of the mine to be evaluated and restored (it should be noted that the soil adsorption evaluation index and the soil recovery evaluation index are dimensionless values, so they can be directly calculated), perform sum analysis, and obtain the geological evaluation value after each restoration stage, and perform proportion analysis on the soil adsorption evaluation index and the soil recovery evaluation index with the geological evaluation value and value after the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0053] In this implementation plan, by standardizing different geological environmental data (such as soil charge density, porosity, water conductivity, etc.) after each restoration stage, the deviation caused by unit differences between data is eliminated, thereby ensuring the comparability of data, thus avoiding the impact of different dimensions on the final evaluation results, and thus providing a solid data foundation for subsequent scientific analysis and restoration strategy formulation. Secondly, by processing soil adsorption and soil restoration indicators step by step, and then combining them to obtain geological environment restoration evaluation indicators, it is possible to evaluate the restoration effect from multiple angles and in an all-round manner. The soil adsorption index mainly reflects the soil adsorption and soil restoration index. The soil's capacity to hold water and pollutants, and the soil restoration index reflects the soil's self-repair and recovery ability. By comprehensively analyzing these indicators, we can fully understand the degree of improvement and restoration effect of the soil environment, and then scientifically guide the subsequent ecological restoration measures of the mine. Finally, by performing mean analysis and proportion analysis on the soil restoration indicators at each restoration stage, it is ensured that the restoration effect of each restoration stage can be accurately evaluated in time and space, which helps to discover problems and make adjustments in a timely manner, thereby enhancing the responsiveness and operability of mine ecological restoration, and then ensuring the efficiency and scientificity of the restoration process.

[0054] Specifically, the specific steps for obtaining the water quality environmental restoration evaluation index after each restoration stage of the mine to be evaluated and restored are as follows: obtain the reference value of the water nutrient concentration after each restoration stage of the mine to be evaluated and restored, and normalize it in combination with the water transmittance value, water viscosity value, water nutrient concentration value, water dissolved gas partial pressure value, water hazardous substance concentration value, water optical density value, and water surface tension value of each water quality measurement point; perform normalization on the reference value of the water nutrient concentration after each restoration stage after normalization and the water transmittance value, water viscosity value, water nutrient concentration value, water dissolved gas partial pressure value, water hazardous substance concentration value, water optical density value, and water surface tension value of each water quality measurement point. The gas partial pressure values ​​are comprehensively analyzed to obtain the water self-purification assessment index after each restoration stage of the mine to be evaluated and remediated; and the water hazardous substance concentration values, water optical density values, and water surface tension values ​​at each water quality measurement point after the normalization processing are completed after each restoration stage of the mine to be evaluated and remediated, to obtain the water pollution assessment index after each restoration stage of the mine to be evaluated and remediated; and the water self-purification assessment indicators and water pollution assessment indicators after each restoration stage of the mine to be evaluated and remediated, to obtain the water quality environment restoration assessment index after each restoration stage of the mine to be evaluated and remediated.

[0055] The formulas for calculating the water body self-purification assessment index, water body pollution assessment index, and water quality environment restoration assessment index after each restoration stage of the mine to be assessed and restored are as follows:

[0058] It needs to be explained that λ i1 , i2 , i3 , i4 The specific acquisition process is as follows: read the water transmittance value, water viscosity value, water nutrient concentration value, and water dissolved gas partial pressure value of each water quality measurement point after the normalization processing of the mine to be evaluated for restoration, perform mean analysis, and obtain the mean value of water transmittance, mean value of water viscosity, mean value of water nutrient concentration, and mean value of water dissolved gas partial pressure after the normalization processing of the mine to be evaluated for restoration after each restoration stage, and perform sum analysis to obtain the self-purification sum value after the end of each restoration stage, and perform proportion analysis on the mean value of water transmittance, mean value of water viscosity, mean value of water nutrient concentration, and mean value of water dissolved gas partial pressure after the end of each restoration stage of the mine to be evaluated for restoration after normalization, respectively, and the self-purification sum value after the end of the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0059] θ i1 ,θ i2 ,θ i3 The specific acquisition process is: read the normalized water hazardous substance concentration value, water optical density value, and water surface tension value of each water quality measurement point after the end of each restoration stage of the mine to be evaluated for restoration, perform mean analysis, and obtain the mean value of water hazardous substance concentration, water optical density, and water surface tension after the end of each restoration stage of the mine to be evaluated for restoration, and perform sum analysis to obtain the pollution sum value after the end of each restoration stage, and perform proportion analysis on the mean value of water hazardous substance concentration, water optical density, and water surface tension after each restoration stage of the mine to be evaluated for restoration after normalization and the pollution sum value after the end of the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0060] The specific acquisition process is: read the water self-purification assessment index and water pollution assessment index after each restoration stage of the restoration mine to be evaluated (it should be noted that the water self-purification assessment index and water pollution assessment index are dimensionless values, so they can be directly calculated), perform sum analysis, and obtain the water quality assessment and value after each restoration stage. Perform a proportion analysis on the water self-purification assessment index and water pollution assessment index after each restoration stage of the restoration mine to be evaluated and the water quality assessment and value after the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0061] In this implementation plan, by normalizing and comprehensively analyzing multiple water quality indicators (such as water transmittance, viscosity, nutrient concentration, dissolved gas partial pressure, etc.), it is possible to comprehensively evaluate the self-purification capacity and pollution status of the water body, which in turn helps to understand various aspects of water quality restoration, and form a panoramic understanding of water quality restoration from the physical and chemical properties of the water body to the changes in microscopic pollutants. Secondly, the normalization process ensures that the unit differences of different water quality indicators will not affect the final restoration evaluation. All indicators are converted to a unified dimension, making them compatible and comparable during analysis, so as to accurately evaluate the effect of each restoration stage, thereby avoiding errors caused by different measurement methods or unit differences. By performing mean analysis and proportion analysis on various indicators of water self-purification and pollution (such as transmittance, concentration of hazardous substances, surface tension, etc.), we can gain an in-depth understanding of the changes in the self-purification capacity of the water body and the pollution load. In the process of water body restoration, the improvement of self-purification capacity and the reduction of pollutant concentration are important criteria for measuring the restoration effect, so that these key indicators can be accurately quantified. Finally, a more authoritative restoration effect evaluation is obtained through comprehensive multidimensional data analysis, so as to more accurately identify problems in the restoration process, optimize restoration measures, and then improve the overall effect of water quality restoration.

[0062] Specifically, the specific steps for obtaining the plant environmental restoration evaluation index after each restoration stage of the mine to be evaluated and restored are as follows: standardize (i.e., remove the unit) the vegetation coverage values, plant chlorophyll content values, plant root density values, plant root depth values, and plant root respiration rate values ​​of each restoration area after each restoration stage of the mine to be evaluated and restored; and comprehensively analyze the standardized vegetation coverage values, plant chlorophyll content values, plant chlorophyll content values, plant root density values, plant root depth values, and plant root respiration rate values ​​of each restoration area after each restoration stage of the mine to be evaluated and restored, so as to obtain the plant environmental restoration evaluation index after each restoration stage of the mine to be evaluated and restored.

[0063] The formula for calculating the plant environmental restoration evaluation index after each restoration stage of the mine to be evaluated is as follows:

[0064]

[0065] Among them, SwH i is the plant environmental restoration evaluation index after the i-th restoration stage of the mine to be evaluated, ZaD i ' j is the vegetation coverage value of the jth restoration area after the i-th restoration stage of the restoration mine to be evaluated, ω i1 is the coverage factor after the i-th repair phase stored in the database, YuD i ' j is the standardized chlorophyll content of plants in the jth restoration area after the i-th restoration stage of the restoration mine to be evaluated, ω i2 is the chlorophyll coefficient after the end of the i-th restoration stage stored in the database, XmD i ' j is the plant root density value of the jth restoration area after the i-th restoration stage of the restoration mine to be evaluated, ω i3 is the root density coefficient after the end of the i-th restoration stage stored in the database, SmD i ' j is the plant root depth value of the jth restoration area after the i-th restoration stage of the restoration mine to be evaluated, ω i4 is the root density coefficient after the end of the i-th restoration stage stored in the database, XaD i ' j is the standardized plant root respiration rate value of the jth restoration area after the i-th restoration stage of the restoration mine to be evaluated, ω i5 is the root respiration coefficient after the end of the i-th repair stage stored in the database, ω i1 +ω i2 +ω i3 +ω i4 +ω i5 =1,i=1,2,3,…,i 0 ,i 0 is the number of repair stages, j = 1, 2, 3, ..., j 0 , j 0 is the number of repair stages, e is a natural constant and its value is 2.71 in this implementation example.

[0066] It needs to be explained that ω i1 ,ω i2 ,ω i3 ,ω i4 ,ω i5The specific acquisition process is as follows: read the vegetation coverage value, plant chlorophyll content value, plant chlorophyll content value, plant root density value, plant root depth value, and plant root respiration rate value of each restoration area after each restoration stage of the restoration mine to be evaluated after standardized processing, and perform mean analysis to obtain the mean vegetation coverage, plant chlorophyll content, plant chlorophyll content, plant root density, plant root depth, and plant root respiration rate of the restoration mine to be evaluated after each restoration stage after standardized processing, and perform sum analysis to obtain the plant evaluation and value after each restoration stage, and perform proportion analysis on the mean vegetation coverage, plant chlorophyll content, plant chlorophyll content, plant root density, plant root depth, and plant root respiration rate of the restoration mine to be evaluated after each restoration stage after standardized processing and the plant evaluation and value after the end of the corresponding restoration stage, and use the proportion results as the corresponding coefficients.

[0126] In this implementation plan, through standardization processing, it is ensured that the vegetation indicators of different restoration areas are analyzed under the same dimension, eliminating the impact caused by different units or different data ranges, so that the real differences of various restoration indicators can be accurately reflected, which is helpful to evaluate the restoration effect more fairly and objectively. Secondly, a comprehensive analysis is conducted on multiple indicators related to vegetation growth and environmental restoration (such as vegetation coverage, chlorophyll content, root density, root depth, and root respiration rate), so as to comprehensively reflect the multi-dimensional effects of plant growth and mine restoration, thereby providing more accurate data support for evaluating the mine restoration effect. At the same time, by performing mean analysis on the indicators of each restoration area, the average restoration situation of each restoration stage is obtained, and the proportion analysis can accurately understand the weight of each indicator in the overall restoration effect, so as to identify which indicators are the most critical in the restoration process and which aspects need further optimization. Finally, by calculating the plant environmental restoration evaluation indicators after each restoration stage, the effect of mine restoration can be quantified, which helps to understand the effect of the current restoration stage.

[0127] Specifically, the specific steps for identifying abnormal assessment indicators and taking corresponding restoration and remediation measures are as follows: the geological environment restoration assessment indicators, water quality environment restoration assessment indicators, and plant environment restoration assessment indicators after each restoration stage of the mine area to be evaluated and restored are judged and analyzed with the preset geological environment restoration assessment indicator threshold, water quality environment restoration assessment indicator threshold, and plant environment restoration assessment indicator threshold; if the geological environment restoration assessment indicator after each restoration stage of the mine area to be evaluated and restored is lower than or equal to the preset geological environment restoration assessment indicator threshold, the geological environment restoration assessment indicator is marked as an abnormal assessment indicator, and the first ecological restoration and remediation measure is taken. Measures (i.e. soil improvement: for poor soil or poor structure in the restoration area, apply organic fertilizers, lime or humus and other soil improvement materials to improve soil fertility and permeability; windbreak and sand fixation: plant grasses, shrubs or trees on exposed soil to form plant barriers to prevent soil erosion and improve soil structure; artificial structures: build culverts, retaining walls or slope stabilization projects to reduce water erosion and maintain soil stability); if the water quality environment restoration assessment index after each restoration stage of the mine area to be evaluated and restored is lower than or equal to the preset water quality environment restoration assessment index threshold, the water quality environment restoration assessment index will be marked as an abnormal assessment index, and the second bioremediation will be taken. Ecological restoration and remedial measures (i.e. water source purification: installing filtration facilities and sedimentation tanks around water sources or pollution sources, or setting up natural purification systems such as artificial wetlands and floating islands to remove harmful substances in the water; ecological revetment: preventing erosion at the edge of the water body by setting up structures such as plant belts, stones or wooden piles, while improving the ecological restoration capacity of the water body; biological restoration: introducing highly adaptable aquatic species, such as algae and plankton, to promote self-recovery of water quality and decompose organic pollutants in the water); if the plant environmental restoration assessment index after each restoration stage of the mine area to be assessed and restored is lower than or equal to the preset plant environmental restoration assessment index threshold, the plant environmental restoration assessment index threshold shall be increased. It is recorded as an abnormal assessment indicator, and the third ecological restoration and remedial measure is taken (i.e., plant planting: select suitable plant species according to local climate and soil conditions, such as pioneer plants, drought-resistant plants, etc., to help repair bare land and enhance soil coverage; vegetation restoration: focus on restoring native plant populations, promote plant diversity and ecological balance, and avoid the impact of alien invasive species; root system restoration: to restore the plant root system, adopt appropriate irrigation and soil improvement measures, such as applying rhizosphere fertilizers or increasing soil aeration to enhance the growth ability of the root system; nutrient supplementation: according to the needs of plant growth, supplement necessary minerals and nutrients, such as applying organic fertilizers or green manures to promote plant growth and prosperity).

[0128] In this implementation scheme, by comparing and analyzing various environmental restoration assessment indicators of the mine area to be evaluated and restored with the preset thresholds, the restoration environment with problems can be accurately identified. When the restoration indicator is lower than the preset threshold, it is immediately marked as an abnormal assessment indicator, thereby avoiding delayed discovery and processing of problems during the restoration process, thereby improving the sensitivity and timeliness of problem identification. Secondly, personalized restoration plans are provided for each abnormal assessment indicator (geology, water quality, and plant environment), so that different types of restoration problems have different targeted restoration measures, thereby improving the effectiveness of the restoration work. Finally, the restoration work can be subdivided into each restoration stage, which is particularly important for long-term restoration projects. Evaluation and adjustment after the end of each stage will help to gradually optimize the restoration process to ensure that each stage achieves the expected goals.

[0132] By combining and analyzing geological environment, water quality environment and plant environment data, the effect of mine ecological restoration after each restoration stage can be comprehensively evaluated, which can help the restoration team to promptly identify potential problems in the restoration process and take timely remedial measures to improve the overall effect of mine ecological restoration.

[0133] By comprehensively considering the judgment of different environmental indicators and thresholds, it is possible to effectively manage and adjust the ecological restoration work of the mine, and take different restoration and remediation measures based on the judgment results, so as to timely identify abnormal environmental restoration assessment indicators and remedy them, so as to prevent further ecological degradation and ensure the environmental quality of mine ecological restoration.
