Technical Field
[0001] The present invention relates to the technical field of island classification management. Specifically, it relates to a method and system for island classification management based on marine ecological evaluation. Background Art
[0002] The ocean is one of the largest and most important ecosystems on Earth and plays a crucial role in the sustainable development of human society. It is not only a treasure trove of natural resources on which humans depend for survival but also provides important support for global economic activities. As an important part of the marine ecosystem, islands have unique ecological structures and functions. The island ecosystem usually includes various ecosystem types such as the ocean, land, and fresh water. These ecosystems interact and influence each other, jointly constituting the complexity and diversity of the island ecosystem. Due to the special geographical location of islands, their ecosystems are often more vulnerable and are easily affected by human activities and natural factors.
[0003] In addition, many evaluation systems only focus on a certain type of ecological element, such as the marine environment or land vegetation, and lack comprehensive analysis of multiple ecological elements, resulting in one-sided evaluation results that are insufficient to guide effective management. At the same time, some methods usually rely on static evaluation results, unable to timely reflect changes in the ecological situation and unable to dynamically optimize classification management strategies.
[0004] Therefore, a method and system for island classification management based on marine ecological evaluation are proposed. Summary of the Invention

[0037] As a preferred solution of the present invention, a two-factor matrix is configured based on the obtained comprehensive ecological pressure index data and comprehensive ecological restoration ability data, and four quadrants are divided to judge the ecological state of the island and identify the position of the ecological state of the island in the four quadrants, obtaining quadrant data and an ecological classification list of the island, specifically: Step S400.1: Configure a two-factor matrix based on the obtained comprehensive ecological pressure index data and comprehensive ecological restoration ability data.
[0038] The horizontal axis of the two-factor matrix represents the comprehensive ecological pressure index data, and the vertical axis of the two-factor matrix represents the comprehensive ecological restoration ability data. The two-factor matrix is divided into four quadrants by the comprehensive ecological pressure index data and comprehensive ecological restoration ability data. The four quadrants are: high pressure - low restoration area, high pressure - high restoration area, low pressure - high restoration area, and low pressure - low restoration area.
[0039] The high pressure - low restoration area is: the ecosystem is fragile and under great pressure, and needs to be protected first.
[0040] The high pressure - high restoration area is: the ecological pressure is large but the restoration ability is strong, and the development can be moderately controlled.
[0041] The low pressure - high restoration area is: the pressure is small and the restoration ability is strong, and sustainable utilization can be carried out.
[0042] The low pressure - low restoration area is: the pressure is small but the restoration ability is limited, and long-term monitoring is required.
[0043] Step S400.1.1: Define thresholds based on the four divided quadrants. The defined thresholds include: high pressure, low pressure, high restoration, and low restoration.
[0044] High pressure is: , pressure threshold = 50, low pressure is: High restoration is: , restoration ability threshold = 60, low restoration is: .
[0045] Step S400.2: Map the comprehensive ecological pressure index data and comprehensive ecological restoration ability data to the horizontal and vertical axes of the interaction matrix respectively based on the configured two-factor matrix, judge the ecological state of the island according to the defined thresholds, and obtain the ecological state of the island.
[0046] Step S400.3: Based on the obtained ecological status of the islands, use Python to identify the position of the ecological status of the islands in the four quadrants and obtain the quadrant data.
[0047] Step S400.4: Based on the obtained quadrant data, generate a list of ecological classifications of the islands through Excel.
[0048] As a preferred solution of the present invention, classify and refine based on the obtained comprehensive ecological pressure index data, comprehensive ecological restoration ability index data, quadrant data, and the list of ecological classifications of the islands, and dynamically adjust the weights of the comprehensive ecological pressure index data and the comprehensive ecological restoration ability index data and calculate the comprehensive score of the islands to obtain the comprehensive score data. Specifically: Step S500.1: Classify and refine based on the obtained comprehensive ecological pressure index data, comprehensive ecological restoration ability index data, quadrant data, and the list of ecological classifications of the islands to obtain the classification and refinement results.
[0049] The classification and refinement include: refinement rules and refinement methods.
[0050] The refinement rules are to refine the rules for the islands in the four quadrants by combining ecological vulnerability, development needs, and regional priority. Ecological vulnerability is used to judge whether the island has stability according to species diversity and vegetation coverage. Development needs are used to judge whether resource development is required according to development intensity and pollution source distribution. Regional priority is used to adjust the classification results according to unique ecological functions and geographical locations.
[0051] The refinement method is to further adjust the classification results for the islands in the same quadrant among the four quadrants according to the refinement rules. Islands with high ecological vulnerability, even if they are in a strong recovery ability, will be classified as: Priority Protection Areas. Islands with high development needs, even if they are in the High Pressure - High Recovery Area, will be adjusted to: Controlled Development Areas. Islands with high regional priority, even if they are in a stable ecological state, will be adjusted to: Long - term Key Monitoring Objects.
[0052] Step S500.2: Dynamically adjust the weights of the comprehensive ecological pressure index data and the comprehensive ecological restoration ability index data using the Analytic Hierarchy Process.
[0053] The dynamic weight adjustment includes: ecological vulnerability, development needs, and regional priority.
[0054] And The default threshold of the weight is: 0.5. Ecological vulnerability is adjusted for areas with high species diversity and strong ecological scarcity to: =0.7, =0.3, paying more attention to the impact of pressure. Development needs are adjusted for areas close to economic development zones or with significant resource demands to: = 0.4, = 0.6, with greater emphasis on the development potential of restoration capabilities, the regional priority is adjusted for areas with special ecological functions or geographical importance as follows: = 0.6, = 0.4, taking into account both pressure and restoration capabilities.
[0055] Step S500.3: Calculate the comprehensive score of the island based on the weights of the comprehensive ecological pressure index data and the comprehensive ecological restoration ability index data after dynamic weight adjustment, and obtain the comprehensive score data. Specifically: ; In the formula: Step Score is the comprehensive score, used to determine the classification result of the island, is the weight of the comprehensive ecological pressure, indicating the importance of the pressure index in the scoring, is the value of the comprehensive ecological pressure, indicating the level of ecological pressure borne by the island, is the weight of the comprehensive ecological restoration ability, indicating the importance of the restoration ability index in the scoring, is the value of the comprehensive ecological restoration ability, indicating the restoration potential of the island's ecosystem.
[0056] When , the island is classified as a priority protection area or a moderately developed area.
[0057] When , the island is classified as a long-term monitoring area or a general observation area.
[0058] As a preferred solution of the present invention, based on the obtained refined classification results, comprehensive score data, comprehensive ecological pressure index data, and comprehensive ecological restoration ability index data, set management strategies and formulate specific implementation plans. Specifically: Step S600.1: Set management strategies based on the obtained refined classification results, comprehensive score data, comprehensive ecological pressure index data, and comprehensive ecological restoration ability index data.
[0059] The set management strategies include: priority protection areas, controlled development areas, moderately developed areas, and long-term monitoring areas.
[0060] For priority protection areas, for islands with relatively high comprehensive scores and comprehensive ecological pressure index data, the set management strategy is: prohibit all development activities, implement ecological restoration projects for vegetation restoration and pollution source cleanup, and establish ecological monitoring points to track the change trend of the comprehensive ecological pressure index data in real time.
[0061] For controlled development areas, when the comprehensive score For islands with relatively high comprehensive ecological pressure index data and relatively high comprehensive ecological restoration ability index data, the management strategies are set as follows: control the development intensity, stipulate the upper limit of the development area, strengthen the control of pollutant emissions, ensure that the ecological restoration ability is not overly interfered with, and promote the low-carbon economic model.
[0062] Moderate development area. When the comprehensive score For islands with relatively low comprehensive ecological pressure index data and relatively high comprehensive ecological restoration ability index data, the management strategies are set as follows: promote a resource development plan that is coordinated with ecological protection, guide the development of the green economy, and continuously monitor the potential impact of development activities on the comprehensive ecological pressure value.
[0063] Long-term monitoring area. When the comprehensive score For islands with relatively low comprehensive ecological restoration ability index data, the management strategies are set as follows: suspend all resource development plans, establish a long-term monitoring system, evaluate the comprehensive ecological restoration ability index data in real time, prevent potential ecological risks, and give priority to protecting important ecological function areas.
[0064] Step S600.2: Develop a specific implementation plan for the set management strategies.
[0065] The implementation plan includes: priority protection areas, controlled development areas, moderate development areas, and long-term monitoring areas.
[0066] The implementation plan for the priority protection area is: complete the ecological restoration project and the layout of long-term monitoring equipment within one year, and conduct an inspection of the project progress and restoration effect at the beginning of each quarter.
[0067] The implementation plan for the controlled development area is: establish a green development model within two years, and evaluate the impact of development activities on the comprehensive ecological restoration ability value every six months.
[0068] The implementation plan for the moderate development area is: establish a sustainable development system that is coordinated with the ecology, and conduct an assessment of development activities and ecological impacts annually.
[0069] The implementation plan for the long-term monitoring area is: complete the layout of ecological monitoring stations within half a year, and submit monitoring data and analysis reports monthly.
[0070] Step S600.3: When the island is in the implementation plan, dynamically adjust the trigger rules according to the changes in the comprehensive score data, comprehensive ecological pressure index data, and comprehensive ecological restoration ability index data.
[0071] When the comprehensive ecological pressure index data increases by more than 20%, and the comprehensive score data Score drops significantly, it is preferentially adjusted to a priority protection area or a long-term monitoring area.
[0072] When the comprehensive ecological restoration ability index data decreases by more than 15%, the development restrictions are further tightened and it is preferentially adjusted to a priority protection area or a long-term monitoring area.
[0073] When the comprehensive score data step Score increases to 70 or above, and the comprehensive ecological restoration ability index data significantly improves by more than 80%, it is adjusted to a moderately developed area.
[0074] As a preferred solution of the present invention, based on the comprehensive score data, the comprehensive ecological pressure index data, and the comprehensive ecological restoration ability index data, the implementation plan process is evaluated and a summary report is generated, specifically: Step S700.1, evaluate the implementation plan process based on the comprehensive score data, the comprehensive ecological pressure index data, and the comprehensive ecological restoration ability index data to obtain the implementation plan evaluation data, specifically: ; In the formula: is the ecological state change index, a positive value indicates ecological improvement, and a negative value indicates ecological deterioration. is the change amount of the comprehensive ecological pressure value. is the change amount of the comprehensive ecological restoration ability value. is the change amount of the comprehensive score. , , is the weight coefficient, reflecting the contribution degree of each index to the ecological state. is the pressure index weight. is the restoration ability weight. is the comprehensive score weight.

[0119] The vegetation coverage rate is to quantify the vegetation coverage rate. Specifically: ; In the formula: VCR is the vegetation coverage rate, is the vegetation-covered area, is the total area of the island.
[0120] The carbon sequestration capacity is to quantify the carbon sequestration capacity of the target island. Specifically: ; In the formula: CCA is the carbon sequestration capacity, is the number of trees per unit area, is the amount of carbon dioxide absorbed by each tree per year.
[0121] The water conservation capacity is to quantify the water conservation capacity of the target island. Specifically: ; In the formula: WCA is the water conservation capacity, is the average annual rainfall, is the infiltration coefficient of the soil.
[0122] Step S300.2: Calculate the comprehensive ecological restoration ability based on the results of the biodiversity index, vegetation coverage rate, carbon sequestration capacity, and water conservation capacity, and obtain the comprehensive ecological restoration ability data. Specifically: ; In the formula: is the comprehensive ecological restoration ability value, is the k-th restoration ability index value, including BDI, VCR, CCA, WCA, is the k-th weight. BDI is the biodiversity index, VCR is the vegetation coverage rate, CCA is the carbon sequestration capacity, WCA is the water conservation capacity, which is determined by the analytic hierarchy process, and p is the total number of restoration ability indicators.
[0123] In the specific implementation manner, based on the obtained comprehensive ecological pressure index data and comprehensive ecological restoration ability data, a two-factor matrix is configured, and four quadrants are divided to judge the ecological state of the island and identify the position of the ecological state of the island in the four quadrants, obtaining quadrant data and an ecological classification list of the island. Specifically: Step S400.1. Based on the obtained comprehensive ecological pressure index data and comprehensive ecological restoration ability data, configure a two-factor matrix.
[0124] The horizontal axis of the two-factor matrix represents the comprehensive ecological pressure index data, and the vertical axis of the two-factor matrix represents the comprehensive ecological restoration ability data. The two-factor matrix is divided into four quadrants by the comprehensive ecological pressure index data and the comprehensive ecological restoration ability data. The four quadrants are: high pressure - low restoration area, high pressure - high restoration area, low pressure - high restoration area, and low pressure - low restoration area.
[0125] The high pressure - low restoration area is: the ecosystem is fragile and under great pressure, and priority protection is needed.
[0126] The high pressure - high restoration area is: the ecological pressure is great but the restoration ability is strong, and development can be moderately controlled.
[0127] The low pressure - high restoration area is: the pressure is small and the restoration ability is strong, and sustainable utilization can be carried out.
[0128] The low pressure - low restoration area is: the pressure is small but the restoration ability is limited, and long-term monitoring is needed.
[0129] Step S400.1.1. Based on the four divided quadrants, define thresholds for division. The defined thresholds for division include: high pressure, low pressure, high restoration, and low restoration.
[0130] High pressure is: , pressure threshold = 50, low pressure is: , high restoration is: , restoration ability threshold = 60, low restoration is: .
[0131] Step S400.2: Based on the configured two-factor matrix, map the comprehensive ecological stress index data and the comprehensive ecological restoration ability data to the horizontal and vertical axes of the interaction matrix respectively. Determine the ecological status of the island according to the defined threshold for division, and obtain the ecological status of the island.
[0132] Step S400.3: Based on the obtained ecological status of the island, use Python to identify the position of the ecological status of the island in one of the four quadrants, and obtain the quadrant data.
[0133] Step S400.4: Based on the obtained quadrant data, generate a list of ecological classifications of the island through Excel.
[0134] In the specific implementation manner, classify and refine based on the obtained comprehensive ecological stress index data, comprehensive ecological restoration ability index data, quadrant data, and the list of ecological classifications of the island, and dynamically adjust the weights of the comprehensive ecological stress index data and the comprehensive ecological restoration ability index data and calculate the comprehensive score of the island to obtain the comprehensive score data. Specifically: Step S500.1: Classify and refine based on the obtained comprehensive ecological stress index data, comprehensive ecological restoration ability index data, quadrant data, and the list of ecological classifications of the island to obtain the classification refinement result.
[0135] The classification refinement includes: refinement rules and refinement methods.
[0136] The refinement rules are to refine the rules for the islands in the four quadrants by combining ecological vulnerability, development needs, and regional priority. Ecological vulnerability is used to judge whether the island has stability based on species diversity and vegetation coverage rate. Development needs are used to judge whether resource development is required based on development intensity and pollution source distribution. Regional priority is used to adjust the classification result according to unique ecological functions and geographical locations.
[0137] The refinement method is to further adjust the classification result for the islands in the same quadrant among the four quadrants according to the refinement rules. Islands with high ecological vulnerability will be classified as: Priority Protection Areas even if they are in a strong recovery ability area. Islands with high development needs will be adjusted to: Controlled Development Areas even if they are in the high-pressure - high-recovery area. Islands with high regional priority will be adjusted to: Long-term Key Monitoring Objects even if they are in a stable ecological state.
[0138] Step S500.2: Dynamically adjust the weights of the comprehensive ecological stress index data and the comprehensive ecological restoration ability index data using the analytic hierarchy process.
[0139] The dynamic weight adjustment includes: ecological vulnerability, development needs, and regional priority.
[0140] And The default weight threshold is: 0.5. For areas with high species diversity and strong ecological scarcity, the ecological vulnerability is adjusted to: =0.7, =0.3. More attention is paid to the impact of stress. For areas close to economic development zones or with significant resource demands, the development demand is adjusted to: =0.4, =0.6. More emphasis is placed on the development potential of the restoration ability. For areas with special ecological functions or important geographical locations, the regional priority is adjusted to: =0.6, =0.4, considering both stress and restoration ability comprehensively.
[0141] Step S500.3: Calculate the comprehensive score of the island based on the weights of the comprehensive ecological stress index data and the comprehensive ecological restoration ability index data after dynamic weight adjustment, and obtain the comprehensive score data. Specifically: ; In the formula: Step Score is the comprehensive score, used to determine the classification result of the island, is the weight of the comprehensive ecological stress, indicating the importance of the stress index in the score, is the value of the comprehensive ecological stress, indicating the level of ecological stress borne by the island, is the weight of the comprehensive ecological restoration ability, indicating the importance of the restoration ability index in the score, is the value of the comprehensive ecological restoration ability, indicating the restoration potential of the island's ecosystem.
[0142] When , the island is classified as a priority protection area or a moderately developed area.
[0143] When , the island is classified as a long-term monitoring area or a general observation area.
[0144] In the specific implementation, based on the obtained refined classification results, comprehensive score data, comprehensive ecological stress index data, and comprehensive ecological restoration ability index data, set management strategies and formulate specific implementation plans. Specifically: Step S600.1: Set management strategies based on the obtained refined classification results, comprehensive score data, comprehensive ecological stress index data, and comprehensive ecological restoration ability index data.
[0145] The set management strategies include: priority protection areas, controlled development areas, moderately developed areas, and long-term monitoring areas.

[0147] For controlled development areas, when the comprehensive score For islands with relatively high comprehensive ecological stress index data and relatively high comprehensive ecological restoration capacity index data, the management strategies are set as follows: controlling the development intensity, stipulating the upper limit of the development area, strengthening the control of pollutant emissions to ensure that the ecological restoration capacity is not overly interfered with, and promoting the low-carbon economic model.
[0148] For moderately developed areas, when the comprehensive score For islands with relatively low comprehensive ecological stress index data and relatively high comprehensive ecological restoration capacity index data, the management strategies are set as follows: promoting resource development plans coordinated with ecological protection, guiding the development of green economy, and continuously monitoring the potential impact of development activities on the comprehensive ecological stress value.
[0149] For long-term monitoring areas, when the comprehensive score For islands with relatively low comprehensive ecological restoration capacity index data, the management strategies are set as follows: postponing all resource development plans, establishing a long-term monitoring system to evaluate the comprehensive ecological restoration capacity index data in real time and prevent potential ecological risks, and giving priority to protecting important ecological function areas.
[0150] Step S600.2: Develop specific implementation plans for the set management strategies.
[0151] The implementation plans include: priority protection areas, controlled development areas, moderately developed areas, and long-term monitoring areas.
[0152] The implementation plan for the priority protection area is: completing the ecological restoration project and the layout of long-term monitoring equipment within one year, and checking the project progress and restoration effect at the beginning of each quarter.
[0153] The implementation plan for the controlled development area is: establishing a green development model within two years, and evaluating the impact of development activities on the comprehensive ecological restoration capacity value every six months.
[0154] The implementation plan for the moderately developed area is: establishing a sustainable development system coordinated with the ecology, and conducting annual evaluations of development activities and ecological impacts.
[0155] The implementation plan for the long-term monitoring area is: completing the layout of ecological monitoring stations within half a year, and submitting monitoring data and analysis reports monthly.
[0156] Step S600.3: When the island is in the implementation plan, the trigger rules are dynamically adjusted according to the changes in the comprehensive scoring data, the comprehensive ecological pressure index data, and the comprehensive ecological restoration ability index data.
[0157] When the comprehensive ecological pressure index data increases by more than 20% and the comprehensive scoring data Score drops significantly, it is preferentially adjusted to a priority protection area or a long-term monitoring area.
[0158] When the comprehensive ecological restoration ability index data decreases by more than 15%, the development restrictions are further tightened, and it is preferentially adjusted to a priority protection area or a long-term monitoring area.
[0159] When the comprehensive scoring data step Score increases to 70 or above and the comprehensive ecological restoration ability index data significantly improves by more than 80%, it is adjusted to a moderately developed area.
[0160] In the specific implementation manner, an evaluation and a summary report are generated during the implementation plan based on the comprehensive scoring data, the comprehensive ecological pressure index data, and the comprehensive ecological restoration ability index data. Specifically: Step S700.1: An evaluation is carried out during the implementation plan based on the comprehensive scoring data, the comprehensive ecological pressure index data, and the comprehensive ecological restoration ability index data to obtain the implementation plan evaluation data. Specifically: ; Where: is the ecological state change index, a positive value indicates ecological improvement, and a negative value indicates ecological deterioration. is the change amount of the comprehensive ecological pressure value. is the change amount of the comprehensive ecological restoration ability value. is the change amount of the comprehensive score. , , is the weight coefficient, reflecting the contribution degree of each index to the ecological state. is the pressure index weight. is the restoration ability weight. is the comprehensive score weight.
[0161] If the reference data is: , , , and the current data is: , , , then the calculation is: ; ; ; Substituting further into the formula, specifically: ; ; ; Result analysis: , indicating that the ecological state has improved slightly, and there is no need for large-scale classification adjustment. Only continuous monitoring is required.
[0162] Step S700.2: Based on the obtained comprehensive scoring data, comprehensive ecological stress index data, comprehensive ecological restoration ability index data, and implementation plan evaluation data, generate a summary report through Excel.
[0163] The summary report includes: comprehensive scoring data, comprehensive ecological stress index data, comprehensive ecological restoration ability index data, implementation plan evaluation data, classification result data, dynamic evaluation data, ecological state change quantification data, and key suggestions and follow-up plan data.
[0164] Through the above steps, a method for classifying and managing islands based on marine ecological assessment is completed.
[0165] Please refer to Figure 2 , Figure 2 , which is the module framework diagram of a system for classifying and managing islands based on marine ecological assessment provided by the embodiment of the present application.
[0166] The present application further provides a system for classifying and managing islands based on marine ecological assessment, including the following modules: A data acquisition module, configured to acquire marine environment data, terrestrial ecological data, freshwater resource data, and activity data, and perform preprocessing.
[0167] An ecological stress module, configured to configure ecological stress indicators based on the obtained preprocessed marine environment data, terrestrial ecological data, freshwater resource data, and activity data, and perform comprehensive calculation of ecological stress indicators to obtain comprehensive ecological stress index data.
[0168] An ecological restoration module, configured to configure ecological restoration ability indicators based on the obtained preprocessed marine environment data, terrestrial ecological data, freshwater resource data, activity data, and comprehensive ecological stress index data, and perform comprehensive ecological restoration ability calculation to obtain comprehensive ecological restoration ability data A state classification module, configured to configure a two-factor matrix based on the obtained comprehensive ecological stress index data and comprehensive ecological restoration ability data, divide four quadrants, judge the ecological state of the island and identify the position of the ecological state of the island in one of the four quadrants, to obtain quadrant data and an ecological classification list of the island.
[0169] A classification refinement module, which is used to perform classification refinement based on the obtained comprehensive ecological pressure index data, comprehensive ecological restoration ability index data, quadrant data, and the ecological classification list of the island, obtain the classification refinement result, dynamically adjust the weights of the comprehensive ecological pressure index data and the comprehensive ecological restoration ability index data, calculate the comprehensive score of the island, and obtain the comprehensive score data.
[0170] A management strategy module, which is used to set management strategies and formulate specific implementation plans based on the obtained classification refinement result, comprehensive score data, comprehensive ecological pressure index data, and comprehensive ecological restoration ability index data.
[0171] An evaluation report module, which is used to evaluate the implementation plan process and generate a summary report based on the comprehensive score data, comprehensive ecological pressure index data, and comprehensive ecological restoration ability index data.
[0172] In the above content, in actual application, first, obtain marine environmental data, terrestrial ecological data, freshwater resource data, and activity data, and preprocess these data. The marine environmental data is obtained through satellite remote sensing, ocean chromatography remote sensors, and water quality monitoring equipment, specifically including water quality indicators, sea current characteristics, and temperature-salinity characteristics. The terrestrial ecological data is obtained through unmanned aerial vehicle multispectral cameras, high-resolution images, and soil sampling tools, specifically including vegetation cover, soil type, and key species distribution. The freshwater resource data is obtained through water quality monitoring equipment, radar remote sensing, and water resource distribution maps, specifically including water source distribution, reserve information, and water quality data. The activity data is obtained through high-resolution image capture, questionnaires, and interviews, specifically including development intensity, pollution source distribution, and activity frequency. The obtained data undergoes data cleaning, data transformation, and standardization processing. Among them, data cleaning is used to remove outliers and fill in missing values, data transformation is used to unify to the WGS-84 coordinate system, and standardization processing is used to normalize indicators with different dimensions to ensure the accuracy and consistency of the data, providing a scientific basis for subsequent analysis.
[0173] Then, based on the preprocessed marine environmental data, terrestrial ecological data, freshwater resource data, and activity data, configure ecological pressure indicators and perform comprehensive calculations. The ecological pressure indicators include sea-level rise pressure, climate change pressure, development intensity pressure, and pollution pressure. Each indicator accurately quantifies the impact of ecological pressure on the target island. The sea-level rise pressure is calculated through the sea-level rise rate, the development intensity pressure is calculated through the proportion of the developed area and the activity frequency, and the pollution pressure is calculated through the number of pollution sources and the pollutant concentration. After synthesizing each pressure indicator, calculate the comprehensive ecological pressure index data to comprehensively reflect the ecological pressure faced by the target island and provide an accurate pressure assessment for subsequent classification.
[0174] Then, based on the preprocessed ecological data and the comprehensive ecological stress index data, configure the ecological restoration ability indicators and conduct comprehensive calculations. The ecological restoration ability indicators include biodiversity index, vegetation coverage rate, carbon sequestration ability, and water conservation ability. The biodiversity index is calculated through the number of species and the total area. The vegetation coverage rate is calculated through the vegetation coverage area of the target area. The carbon sequestration ability is calculated through the number of trees per unit area and the carbon absorption amount. The water conservation ability is calculated through the average annual rainfall and soil infiltration ability of the target area. After synthesizing various restoration ability indicators, the comprehensive ecological restoration ability data is obtained, comprehensively evaluating the ecological restoration potential of the target island and providing a scientific basis for subsequent classified management.
[0175] Then, based on the comprehensive ecological stress index data and the comprehensive ecological restoration ability index data, construct a two-factor matrix and classify the ecological status of the target island. The horizontal axis of the two-factor matrix is the comprehensive ecological stress index data, and the vertical axis is the comprehensive ecological restoration ability index data. The matrix is divided into four quadrants: high pressure - low restoration area, high pressure - high restoration area, low pressure - high restoration area, and low pressure - low restoration area. By mapping the data of the target island to the two-factor matrix, accurately judge its ecological status and generate an ecological classification list. The high pressure - low restoration area is a region with a fragile ecosystem and high pressure, which needs to be protected first. The high pressure - high restoration area is a region with relatively high ecological pressure but strong restoration ability, and development can be moderately controlled. The low pressure - high restoration area is a region with low pressure and strong restoration ability, and sustainable utilization can be carried out. The low pressure - low restoration area is a region with low pressure but limited restoration ability, which needs long-term monitoring.
[0176] After that, based on the ecological classification list of the two-factor matrix, combined with ecological vulnerability, development needs, and regional priorities, refine the classification of the target island and calculate the comprehensive score data. The classification refinement further optimizes the classification results by adjusting the weights of the comprehensive ecological stress index data and the comprehensive ecological restoration ability index data. Islands with high ecological vulnerability, even if they are in the quadrant with strong restoration ability, are classified as priority protection areas. Islands with high development needs, even if they are in the high pressure - high restoration area, are adjusted to controlled development areas. Islands with high regional priorities, even if their ecological status is stable, are classified as long-term key monitoring objects. The comprehensive score data accurately quantifies the classification results of the target island and provides a basis for formulating management strategies.
[0177] Subsequently, based on the classification refinement results and comprehensive scoring data, management strategies and implementation plans for the target island are formulated. The management strategies for the priority protection area include prohibiting development activities, implementing vegetation restoration and pollution source cleanup, and establishing ecological monitoring points. The management strategies for the controlled development area include controlling the development intensity, strengthening pollutant emission control, and promoting a low-carbon economic model. The management strategies for the moderate development area include promoting sustainable resource development and continuously monitoring the ecological impact of development activities. The management strategies for the long-term monitoring area include suspending the resource development plan and setting up a long-term monitoring system to evaluate the ecological status in real time. The implementation plan clarifies the time nodes and responsible units for each management strategy to ensure that the implementation effect meets the expectations.
[0178] Finally, during the implementation of the management strategies, the ecological status of the target island is dynamically evaluated by integrating the comprehensive ecological stress index data, comprehensive ecological restoration ability index data, and comprehensive scoring data. When the comprehensive ecological stress index data increases by more than 20% or the comprehensive ecological restoration ability index data decreases by more than 15%, a dynamic adjustment mechanism is triggered to reclassify the island and optimize the management strategies. At the same time, by generating a summary report to record the classification results, dynamic evaluation data, and the completion of the implementation plan, the summary report provides a scientific basis for subsequent island management to ensure that the management strategies can adapt to changes in the ecological status.
[0179] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
