Description

Technical Field

[0001] The present invention relates to the technical field of ecological data analysis, and in particular to a method for evaluating the ecological restoration effect of a slope of a pumped-storage power station. Background Art

[0002] Global climate change has led to frequent extreme weather events, such as droughts, floods, and extreme temperatures. These events have a significant impact on the success of ecological restoration projects. Under extreme climatic conditions, the vulnerability of ecosystems increases, and more accurate and timely assessment methods are needed to monitor and guide ecological restoration work. Different ecological restoration measures may have different adaptability and effects to extreme weather, and assessment methods are needed to distinguish and optimize these measures. Ecological restoration is a long-term process that requires continuous management and adjustment. Under extreme weather conditions, this management need becomes more urgent and complex.

[0003] The patent document with publication number CN107506939A discloses a method for assessing the suitability of riparian ecological restoration measures, including the current status assessment of the riparian zone to be restored, the construction and systematic classification of the ecological restoration measures library, the division of riparian zone type areas for preliminary selection of restoration measures, the determination of the dominant function of the riparian zone for the optimization of the preliminary selected measures, and the final suitable restoration measures based on the site conditions of the riparian zone. It can be seen that the assessment process may take a long time to complete. For environmental issues that require a quick response, this method is not fast enough. In addition, this method does not provide a mechanism for regularly updating data and cannot reflect the rapid changes in the riparian environment in a timely manner. Summary of the invention

[0023] When the freezing season repair state characterization value is less than the preset standard freezing season characterization value, the repair level is determined to be a low repair level, and a repair effect evaluation prompt that freezing season repair measures are required is output;

[0025] Furthermore, within the preset correction time, the number of output repair effect evaluation prompts that require repair measures is obtained. When the number is greater than the preset number of standard evaluation prompts, the difference between the number of repair effect evaluation prompts that require repair measures and the number of standard evaluation prompts is calculated, and the ratio of the difference to the number of standard evaluation prompts is calculated and multiplied by the preset evaluation time to obtain the corrected evaluation time.

[0026] A pumped storage power station slope ecological restoration effect evaluation system, based on the above-mentioned pumped storage power station slope ecological restoration effect evaluation method, comprises:

[0027] Data acquisition module, used to monitor the real-time ambient temperature, real-time rainfall, real-time slope erosion area, real-time soil temperature, real-time soil moisture and real-time vegetation coverage rate of the pumped storage power station slope ecological restoration area;

[0028] A restoration state characterization value calculation module, connected to the data acquisition module, is used to adjust a preset soil moisture weight and a preset vegetation coverage weight according to all real-time soil moisture and all real-time ambient temperature within a preset evaluation period, and calculate a dry season restoration state characterization value according to the adjustment result, the real-time soil moisture and the real-time vegetation coverage;

[0034] Compared with the prior art, the beneficial effects of the present invention are that, through real-time monitoring and dynamic weight adjustment, the accuracy and adaptability of the evaluation results are ensured, and environmental changes can be responded to in a timely manner. By comprehensively considering multiple environmental parameters, a comprehensive ecological restoration status analysis is provided. The different restoration levels are clearly distinguished through the evaluation results, providing clear guidance for taking targeted restoration measures. In addition, automation and information processing improve work efficiency, and the self-adjustment mechanism of the evaluation time makes the evaluation process more flexible and continuously optimized, which helps to achieve long-term ecological monitoring and management, and effectively solves the problem of inaccurate evaluation of restoration effects due to the inability to adjust ecological restoration measures in a timely manner due to insufficient adaptability to extreme climatic conditions.

[0035] Furthermore, through real-time monitoring and data analysis, the lack of soil moisture during the dry season can be captured in time, and the weights of the assessment parameters can be dynamically adjusted accordingly to ensure that the assessment results are more in line with the actual ecological conditions. Standardization enhances the objectivity and comparability of the assessment, and the weight adjustment mechanism allows the system to have greater influence on key environmental indicators, thereby achieving more effective resource allocation and strategy formulation in the process of ecological restoration. In addition, by quantifying the representation value of the dry season restoration state, this method provides decision makers with a clear assessment basis and action guide, which helps to improve the response speed and implementation effect of ecological restoration measures and promote the rapid recovery and long-term stability of slope ecosystems.

[0036] Furthermore, through real-time monitoring and dynamic weight adjustment, the impact of soil temperature in the frozen season on vegetation growth can be accurately captured, ensuring the timeliness and adaptability of the evaluation results. Standardization enhances the objectivity of the evaluation and the comparability across time periods, making the evaluation results more accurate and reliable. In addition, by adjusting the weights of soil temperature and vegetation coverage, the importance of these two indicators to ecological restoration in the cold season is emphasized, which helps to identify key ecological problems and prioritize their resolution. It also provides clear indicators of ecological restoration status in the frozen season to assist in the formulation of targeted restoration strategies, such as soil insulation and vegetation selection, thereby improving the effectiveness and efficiency of ecological restoration measures.

[0037] Furthermore, by dynamically adjusting the weights, the focus on key ecological indicators was strengthened, especially in the assessment of soil erosion and vegetation stability. The standardized processing not only improved the accuracy and consistency of the assessment, but also made cross-period and cross-regional comparisons possible. In addition, by quantifying the changes in vegetation coverage and soil moisture, it provided a clear direction and basis for ecological restoration measures, which helped to adopt more effective soil and water conservation and vegetation restoration strategies, significantly improved the ecological stability and restoration efficiency of slopes in the rainy season, reduced environmental risks, and promoted the rapid recovery and long-term health of the ecosystem.

[0038] Furthermore, through real-time monitoring and seasonal judgment, the timeliness and pertinence of ecological restoration measures are ensured, thereby improving the efficiency and effectiveness of restoration work. Dynamic weight adjustment and standardized processing enhance the accuracy and scientific nature of the assessment, making the assessment results more real and reliable. In addition, by outputting specific restoration measures prompts, a clear action guide is provided for decision makers, which helps to quickly respond to ecological problems and reduce environmental risks. At the same time, the self-adjustment mechanism of the assessment duration makes the assessment process more flexible and continuously optimized, adapting to the needs of ecological restoration in different seasons and environmental conditions.

[0047] See also Figure 1 As shown, it is a flow chart of the method for evaluating the ecological restoration effect of the pumped storage power station slope in this embodiment;

[0048] This embodiment provides a method for evaluating the ecological restoration effect of a pumped storage power station slope, including:

[0049] Monitor the real-time ambient temperature, real-time rainfall, real-time slope erosion area, real-time soil temperature, real-time soil moisture and real-time vegetation coverage rate in the ecological restoration area of ​​the pumped storage power station slope;

[0050] Adjust the preset soil moisture weight and the preset vegetation coverage weight according to all real-time soil moisture and all real-time ambient temperature within the preset evaluation time, and calculate the dry season restoration state characterization value according to the adjustment result, the real-time soil moisture and the real-time vegetation coverage;

[0051] Adjust the preset soil temperature weight and the preset vegetation coverage weight according to all real-time ambient temperatures and all real-time soil temperatures within the evaluation period, and calculate the frozen season restoration state characterization value according to the adjustment result, the real-time soil temperature and the real-time vegetation coverage;

[0052] The preset change rate weight and the preset soil moisture weight are adjusted according to the total real-time slope erosion area and the total real-time rainfall within the assessment period, and the rainy season restoration status characterization value is calculated according to the adjustment result, the real-time soil moisture and the real-time vegetation coverage rate;

[0053] Determine the corresponding restoration level according to the dry season restoration state characterization value, the frozen season restoration state characterization value, and the rainy season restoration state characterization value, wherein the restoration level includes a low restoration level and a high restoration level;

[0054] Output corresponding repair effect evaluation prompts according to each repair level;

[0055] The preset evaluation time is modified according to the evaluation prompts of all repair effects within the preset correction time.

[0056] The dry season restoration status characterization value is a quantitative indicator that reflects the effect of slope ecological restoration during the dry season. It is calculated by comprehensively considering all real-time soil moisture and ambient temperature during the assessment period and comparing them with the preset dry season standards. It usually involves standardizing the real-time soil moisture and vegetation coverage data, multiplying them by the corresponding adjusted weights, and summing them to obtain the dry season restoration status characterization value. It is used to determine whether the ecological restoration of the dry season slope has achieved the expected effect and provide a basis for formulating or adjusting dry season restoration measures.

[0057] The frozen season restoration status characterization value is another quantitative indicator used to evaluate the ecological restoration status of slopes in cold seasons. It takes into account the real-time data of soil temperature and ambient temperature and compares them with the preset standards for the frozen season. Similar to the dry season characterization value, it involves standardizing the real-time soil temperature and vegetation coverage data, multiplying them by the adjusted weights, and summing them to obtain the frozen season restoration status characterization value. It helps identify the ecological restoration needs of slopes during the frozen season and guides the adoption of appropriate insulation and vegetation protection measures.

[0058] The rainy season restoration status characterization value reflects the ecological restoration effect of the slope during the rainy season, taking into account factors such as slope erosion area and rainfall. The rainy season restoration status characterization value is obtained by calculating the change rate of vegetation coverage, standardizing the soil moisture and change rate data, multiplying by the adjusted weight, and summing them. The ecological stability and restoration effect of the slope in the rainy season are evaluated to guide the implementation of soil and water conservation and vegetation restoration measures.

[0059] The restoration effect evaluation prompt is a suggestion or warning automatically generated by the system based on the calculation results of the above-mentioned characterization values, which is used to guide the actual ecological restoration work. When the characterization value is lower than the preset standard, it is prompted that specific restoration measures are needed; when the characterization value is higher than or equal to the standard, it may be prompted to maintain the current measures or make slight adjustments. It provides clear guidance for decision makers and ecological restoration implementers, helping them to take timely actions to optimize the ecological restoration effect and ensure the continued health and stability of the slope ecology.

[0060] The preset evaluation duration refers to a fixed time period set in the ecological restoration effect evaluation method for collecting and analyzing data in order to calculate the restoration status characterization value. The evaluation duration usually depends on factors such as the scale of the ecological restoration project, the ecological conditions of the slope, the expected vegetation growth cycle, seasonal changes, etc. There is usually no fixed duration, but the common evaluation duration may vary from a few months to a year, depending on the project requirements and the monitoring frequency of ecological changes. In this embodiment, the preset evaluation duration is set to a seasonal cycle, such as three months (a season) or a year, so as to cover ecological changes in different seasons. By setting a reasonable evaluation duration, it can be ensured that enough data is collected to accurately evaluate the effect of ecological restoration, while avoiding the waste of resources caused by too frequent evaluations.

[0061] The preset correction duration refers to the time interval used to adjust the evaluation strategy according to the actual evaluation results in the evaluation method. The setting of the correction duration is usually based on the changing speed of the ecological restoration effect, seasonal factors, the dynamic process of vegetation recovery, etc. The correction duration is usually set to an integer multiple of the evaluation duration. For example, if the evaluation duration is one year, the correction duration is set to half a year or one year. In this embodiment, the preset correction duration is set to half of the evaluation duration so that the evaluation strategy can be adjusted in time after the end of each season. By setting the correction duration, the evaluation method and restoration measures can be flexibly adjusted according to the actual progress of ecological restoration and seasonal changes, thereby improving the adaptability and effectiveness of the restoration work.

[0062] The preset soil moisture weight, preset vegetation cover weight, preset soil temperature weight, preset vegetation cover weight, preset rate of change weight, and preset soil moisture weight are all set to 0.5, based on the consideration of the balance of various factors in the ecosystem. When the data quality and reliability of all indicators are comparable, equal weight distribution will be chosen. Equal weighting is used as a simplified method when there is no guidance for initial setting of specific seasonal or environmental conditions. In the absence of specific environmental conditions, equal weighting provides a general assessment method. Weights can be adjusted based on seasonal changes or specific environmental events to improve the accuracy of assessments and the effectiveness of restoration measures.

[0063] The evaluation method for the ecological restoration effect of the slope of the pumped storage power station involves real-time monitoring of multiple key environmental parameters in the slope area, including ambient temperature, rainfall, slope erosion area, soil temperature, soil moisture and vegetation coverage. Based on these monitoring data, the system will dynamically adjust the weights of indicators such as soil moisture, soil temperature, and vegetation coverage to adapt to environmental conditions in different seasons. The evaluation method will evaluate the ecological restoration effect of the slope by calculating the restoration state characterization values ​​in the dry season, frozen season, and rainy season, and then determine the restoration level and output the corresponding restoration effect evaluation prompts. In addition, the evaluation duration will be adjusted according to the number of evaluation prompts in a certain period to optimize the evaluation frequency and accuracy.

[0064] Through real-time monitoring and dynamic weight adjustment, the accuracy and adaptability of the assessment results are ensured, and timely response to environmental changes can be achieved. By comprehensively considering multiple environmental parameters, a comprehensive ecological restoration status analysis is provided. The assessment results clearly distinguish different restoration levels, providing clear guidance for taking targeted restoration measures. In addition, automation and information processing improve work efficiency. The self-adjustment mechanism of the assessment time makes the assessment process more flexible and continuously optimized, which helps to achieve long-term ecological monitoring and management.

[0065] Please continue reading Figure 2 As shown, it is a decision logic diagram for determining and adjusting the soil moisture weight in this embodiment;

[0066] Specifically, the average value of all real-time soil moisture and the average value of all real-time ambient temperature within the evaluation period are calculated.

[0067] When the average value of all real-time soil moisture is less than the preset standard average soil moisture, the average value of all real-time ambient temperatures is greater than the preset standard dry season ambient temperature, and the difference between the average value of all real-time soil moisture and the standard average soil moisture within the evaluation period is greater than the preset standard soil moisture deviation, calculate the ratio of the difference between the average value of all real-time soil moisture and the preset standard average soil moisture and the standard soil moisture deviation, increase and adjust the soil moisture weight according to the calculated ratio, and adjust the vegetation coverage weight according to the adjusted soil moisture weight.

[0068] Specifically, all real-time soil moisture and all real-time vegetation coverage within the evaluation period are standardized to obtain standardized soil moisture and standardized vegetation coverage, the product of standardized soil moisture and the adjusted soil moisture weight is calculated, and the product of standardized vegetation coverage and the adjusted vegetation coverage weight is calculated. The two calculated products are summed to obtain the dry season restoration status characterization value.

[0069] The preset standard average soil moisture is a reference value used to evaluate the appropriate level of soil moisture under specific conditions. It depends on the local climate, soil type, vegetation requirements, and historical average soil moisture data. The specific value varies according to the region and soil type, and is usually determined based on long-term climate data and soil research. In this embodiment, a standard value of 20% is set based on the historical average soil moisture in the area. It helps to evaluate whether the current soil moisture meets the needs of vegetation growth and take timely measures to improve soil conditions.

[0070] The preset standard dry season ambient temperature is a reference temperature for evaluating the ambient temperature during the dry season. It depends on the climate characteristics of the dry season in the region and the historical temperature data. It is usually set according to the historical highest and lowest temperature data to ensure that the evaluation is still representative under extreme conditions. In this embodiment, it is set to the average temperature of 35°C in the dry season in the region as the benchmark for evaluation. It helps to determine the thermal stress of vegetation under extreme temperatures in the dry season and guide management measures such as irrigation and shading.

[0071] The preset standard soil moisture deviation is an allowable soil moisture fluctuation range used to evaluate the stability and consistency of soil moisture. It depends on the sensitivity of soil moisture to vegetation growth and the resilience of the ecosystem. It is usually set to a smaller percentage to ensure that the soil moisture remains in a suitable range. In this embodiment, it is set to ±10% to ±20% of the standard average soil moisture to accommodate slight environmental changes. A buffer zone is provided to allow a certain degree of soil moisture fluctuation while ensuring timely action when the soil moisture is too low.

[0072] By calculating the average value of real-time data of soil moisture and ambient temperature during the evaluation period and comparing it with the preset standard, it is determined whether the soil moisture weight needs to be adjusted. When the soil moisture is lower than the standard and the deviation is significant, the soil moisture weight is adjusted by calculating the ratio of the difference to the standard deviation, thereby affecting the vegetation coverage weight. Subsequently, the real-time soil moisture and vegetation coverage data are standardized and multiplied by the corresponding adjusted weights, and the sum is obtained to obtain the dry season restoration state characterization value, thereby quantifying the ecological restoration effect in the dry season.

[0073] Through real-time monitoring and data analysis, the lack of soil moisture during the dry season can be captured in time, and the weights of the assessment parameters can be dynamically adjusted accordingly to ensure that the assessment results are more in line with the actual ecological conditions. Standardization enhances the objectivity and comparability of the assessment, and the weight adjustment mechanism allows the system to have a greater influence on key environmental indicators, thereby achieving more effective resource allocation and strategy formulation in the process of ecological restoration. In addition, by quantifying the representation value of the dry season restoration state, this method provides decision makers with a clear assessment basis and action guide, which helps to improve the response speed and implementation effect of ecological restoration measures and promote the rapid recovery and long-term stability of slope ecosystems.

[0074] Please continue reading Figure 3 As shown, it is a decision logic diagram for determining and adjusting the soil temperature weight in this embodiment;

[0075] Specifically, the average value of all real-time soil temperatures during the evaluation period is calculated.

[0076] When the average value of all real-time soil temperatures is lower than the preset standard average soil temperature, the average value of all real-time ambient temperatures is lower than the preset standard freezing season ambient temperature, and the difference between the average value of all real-time soil temperatures and the standard average soil temperature within the evaluation period is higher than the preset standard soil temperature deviation, the ratio of the difference between the average value of all real-time soil temperatures and the preset standard average soil temperature and the standard soil temperature deviation is calculated, and the soil temperature weight is adjusted according to the calculated ratio, and the preset vegetation coverage weight is adjusted according to the adjusted soil temperature weight.

[0077] Specifically, all real-time soil temperatures and all real-time vegetation coverage rates within the evaluation period are standardized to obtain standardized soil temperatures and standardized vegetation coverage rates, the product of the standardized soil temperature and the adjusted soil temperature weight is calculated, the product of the standardized vegetation coverage rate and the adjusted vegetation coverage rate weight is calculated, the two calculated products are summed to obtain the characterization value of the frozen season repair status.

[0078] Preset standard average soil temperature This is a reference value used to evaluate the appropriate level of soil temperature under specific conditions. It depends on local climate conditions, soil type, temperature preference of vegetation roots, and historical average soil temperature data. It is usually set according to regional climate characteristics and soil type, based on long-term climate and soil temperature monitoring data. In this embodiment, it is set to the average soil temperature in the region throughout the year, for example, 12°C to 15°C. It helps to determine whether the soil temperature is suitable for vegetation growth, especially when planning insulation measures before the freezing season.

[0079] The preset standard freezing season ambient temperature is a reference temperature for evaluating the ambient temperature in the cold season, and is used to determine the low temperature that may affect the vegetation. It depends on the climate characteristics of the freezing season in the area and the historical minimum temperature data. It is usually set to the average temperature of the historical freezing season in the area or a temperature slightly lower than this average. In this embodiment, it is set to 0°C as a warning temperature near the freezing point, prompting to take insulation measures. Ensure that the vegetation is not frozen under extreme low temperature conditions, and guide the use of covering materials and emergency insulation measures.

[0080] The preset standard soil temperature deviation is an allowable soil temperature fluctuation range used to evaluate the stability and consistency of soil temperature. It depends on the sensitivity of vegetation to soil temperature changes and the adaptability of the soil ecosystem. It is usually set to a smaller temperature range, such as ±2°C to ±3°C, to ensure that the soil temperature is suitable and stable. In this embodiment, it is set to ±2°C to provide a buffer zone to adapt to daily temperature fluctuations. A certain degree of soil temperature fluctuation is allowed, while ensuring that timely action is taken when the soil temperature is too low.

[0081] First, the real-time average values ​​of soil temperature and ambient temperature during the evaluation period are calculated and compared with the preset frozen season standards and deviations. When the monitored soil temperature is lower than the standard value and the deviation is significant, the soil temperature weight is dynamically adjusted through ratio analysis, thereby affecting the vegetation coverage weight. Subsequently, the soil temperature and vegetation coverage data are standardized and multiplied by the corresponding adjusted weights. The sum is used to obtain the frozen season restoration status characterization value, which is used to quantify the ecological restoration effect of the slope in the cold season.

[0082] Through real-time monitoring and dynamic weight adjustment, the impact of soil temperature in the frozen season on vegetation growth can be accurately captured, ensuring the timeliness and adaptability of the evaluation results. Standardization enhances the objectivity of the evaluation and the comparability across time periods, making the evaluation results more accurate and reliable. In addition, by adjusting the weights of soil temperature and vegetation coverage, the importance of these two indicators to ecological restoration in the cold season is emphasized, which helps to identify key ecological problems and prioritize their resolution. It also provides clear indicators of ecological restoration status in the frozen season to assist in the formulation of targeted restoration strategies, such as soil insulation and vegetation selection, thereby improving the effectiveness and efficiency of ecological restoration measures.

[0083] Specifically, the average value of all real-time slope erosion areas and the average value of all real-time rainfall within the evaluation period are calculated.

[0084] When the average value of all real-time slope erosion areas is greater than the preset standard average slope erosion area, the average value of all real-time rainfall is greater than the preset standard rainfall, and the difference between the average value of all real-time slope erosion areas and the standard average slope erosion area within the assessment period is greater than the preset standard slope erosion area deviation, calculate the ratio of the difference between the average value of all real-time slope erosion areas and the standard average slope erosion area and the standard slope erosion area deviation, increase the adjusted change rate weight according to the calculated ratio, and adjust the preset soil moisture weight according to the adjusted change rate weight.

[0085] Specifically, the difference between the real-time vegetation coverage rate before the evaluation period and the total real-time vegetation coverage rate within the evaluation period is calculated, the ratio of each difference to the evaluation period is calculated, and the change rate of the total real-time vegetation coverage rate is obtained. The total real-time soil moisture and the change rate of the total real-time vegetation coverage rate within the evaluation period are standardized respectively to obtain the standardized soil moisture and the standardized change rate, the product of the standardized soil moisture and the adjusted soil moisture weight is calculated, the product of the standardized change rate and the adjusted change rate weight is calculated, the two calculated products are summed to obtain the rainy season restoration status characterization value.

[0086] The preset standard average slope erosion area is a reference value used to evaluate the average area lost by the slope due to erosion within a certain period of time. It depends on factors such as the geological conditions of the slope, vegetation coverage, rainfall intensity, and historical erosion data. It is usually set based on historical erosion rates and geographic information system (GIS) analysis, and is usually an average value reflecting the stability of the slope. In this embodiment, it is set to the annual average erosion area derived from long-term monitoring data. It helps to promptly discover situations that exceed the normal erosion rate, so as to take corresponding soil and water conservation measures.

[0087] The preset standard rainfall is the standard rainfall for evaluating the impact of rainfall on the slope within a certain period of time. It depends on the local climate conditions, rainfall patterns, topography and drainage capacity. It is usually set based on historical rainfall data, such as the average rainfall over many years. In this embodiment, it is set as the average rainfall in the area as a benchmark for evaluating slope erosion. It helps to evaluate the impact of rainfall on slope erosion and guide the formulation of corresponding drainage and vegetation restoration measures.

[0088] The preset standard slope erosion area deviation is an allowable range of slope erosion area fluctuations, which is used to evaluate the stability and consistency of the erosion rate. It depends on the natural volatility of slope erosion, monitoring accuracy, and vegetation recovery capacity. It is usually set to a relatively small range, such as ±10% to ±20% of the standard erosion area. In this embodiment, it is set to ±15% to accommodate seasonal rainfall changes and natural fluctuations in erosion rates. A buffer zone is provided to allow a certain degree of erosion area variation while ensuring that timely countermeasures are taken when the erosion rate is abnormal.

[0089] By calculating the average values ​​of slope erosion area and rainfall during the evaluation period and comparing them with the preset standards and deviations, it is possible to identify whether the weights need to be adjusted. When the average values ​​of slope erosion area and rainfall exceed the preset standards and the difference is significant, the system will adjust the change rate weight and soil moisture weight according to this deviation. Furthermore, by calculating the change rate of vegetation coverage, standardizing the soil moisture and vegetation coverage change rate data, multiplying them by the corresponding adjusted weights, and summing them to obtain the rainy season restoration state representation value, the ecological restoration effect of the slope in the rainy season can be quantified.

[0090] By dynamically adjusting the weights, the focus on key ecological indicators is strengthened, especially in the assessment of soil erosion and vegetation stability. The standardized processing not only improves the accuracy and consistency of the assessment, but also makes cross-period and cross-regional comparisons possible. In addition, by quantifying the changes in vegetation coverage and soil moisture, it provides a clear direction and basis for ecological restoration measures, which helps to adopt more effective soil and water conservation and vegetation restoration strategies, and can significantly improve the ecological stability and restoration efficiency of slopes in the rainy season, reduce environmental risks, and promote the rapid recovery and long-term health of the ecosystem.

[0091] Specifically, when the dry season restoration state representation value is less than the preset standard dry season representation value, the restoration level is determined to be a low restoration level, and a restoration effect evaluation prompt that dry season restoration measures are required is output;

[0092] When the freezing season repair state characterization value is less than the preset standard freezing season characterization value, the repair level is determined to be a low repair level, and a repair effect evaluation prompt that freezing season repair measures are required is output;

[0093] When the rainy season restoration status characterization value is less than the preset standard rainy season characterization value, the restoration level is determined to be a low restoration level, and a restoration effect evaluation prompt is outputted indicating that rainy season restoration measures are required.

[0094] Specifically, within the preset correction time, the number of output repair effect evaluation prompts that require repair measures is obtained. When the number is greater than the preset number of standard evaluation prompts, the difference between the number of repair effect evaluation prompts that require repair measures and the number of standard evaluation prompts is calculated, and the ratio of the difference to the number of standard evaluation prompts is calculated and multiplied by the preset evaluation time to obtain the corrected evaluation time.

[0095] The ecological restoration effects in different seasons are determined by setting standard characterization values, and corresponding restoration measures prompts are output accordingly. Specifically, the evaluation process involves real-time monitoring of key indicators such as soil moisture, ambient temperature, soil temperature, slope erosion area and rainfall in the dry season, frozen season and rainy season, and calculating the restoration status characterization values ​​of each season. When the characterization value is lower than the preset standard, the system automatically determines it as a low restoration level and outputs corresponding seasonal restoration measures prompts. In addition, the evaluation duration will be dynamically adjusted based on the difference between the number of restoration prompts output within a certain period and the preset standard to optimize the evaluation frequency and timing.

[0096] Through real-time monitoring and seasonal judgment, the timeliness and pertinence of ecological restoration measures are ensured, thereby improving the efficiency and effectiveness of restoration work. Dynamic weight adjustment and standardized processing enhance the accuracy and scientificity of the assessment, making the assessment results more real and reliable. In addition, this method provides decision makers with a clear action guide by outputting specific restoration measures prompts, which helps to quickly respond to ecological problems and reduce environmental risks. At the same time, the self-adjustment mechanism of the assessment duration makes the assessment process more flexible and continuously optimized, adapting to the needs of ecological restoration in different seasons and environmental conditions.
