[0002] Island ecosystems are unique ecological types on the earth, with rich biodiversity and important ecological service functions. However, due to the special geographical location of islands, their ecosystems are often relatively fragile and are easily threatened by multiple factors such as climate change, sea-level rise, and human activities.

[0003] In recent years, with the intensification of global climate change and the increase in human development activities, the pressure on the ecological environment of islands has been increasing day by day, and problems such as ecosystem degradation, biodiversity loss, and environmental pollution have become increasingly prominent.

[0144] The obtained endpoint base values ​​are comprehensively calculated to obtain the ecological comprehensive assessment factor, which is marked as ,in, , Represents the health endpoint value, Indicates the pressure endpoint value, Indicates the recovery endpoint value;

[0145] Conditioning the obtained ecological comprehensive assessment factors to obtain optimal conditions, and ranking and positioning the ecological comprehensive assessment factors according to the obtained optimal conditions to obtain the ecological optimal node;

[0146] The optimization condition indicates that the pressure endpoint value is less than the central change axis and the health endpoint value and the recovery endpoint value are both greater than the central change axis. The sorting and positioning indicates that the ecological comprehensive assessment factors are sorted in descending order to obtain a preferred assessment factor sequence. When the optimization condition is met, the ecological comprehensive assessment factor with the highest ranking in the preferred assessment factor sequence is recorded as the optimal assessment endpoint value, that is, the ecological comprehensive assessment factor with the highest ranking that meets the optimization condition is selected and recorded as the optimal assessment endpoint value; for example, the first-ranked ecological comprehensive assessment factor does not meet the condition that the recovery endpoint value is greater than the central change axis, that is, it does not meet the optimization condition, then the second-ranked ecological comprehensive assessment factor is compared for the optimization condition. If it meets the condition, the second-ranked ecological comprehensive assessment factor is recorded as the optimal assessment endpoint value. If it does not meet the condition, the next ecological comprehensive assessment factor is compared until the optimization condition is met;

[0147] Obtain the district sampling node corresponding to the optimal assessment endpoint value, and mark the obtained district sampling node as the ecological optimal node, indicating that at this point in time, the island's ecological environment is optimal, the island's ecological health index and ecological resilience index are optimal, and the ecological pressure index is the lowest. The island can better resist and adapt to environmental changes and is not affected by human activities. It is in the best ecological environment state;

[0148] The obtained endpoint base values ​​are bottom-screened to obtain ecologically inefficient nodes;

[0149] The bottom screening means performing a secondary measurement on the obtained endpoint base values in the impact base value dynamic diagram. If there are aggregated endpoints satisfying "pressure endpoint value > healthy endpoint value + recovery endpoint value", that is , and obtaining the area sampling nodes corresponding to the aggregated endpoints. The obtained area sampling nodes are denoted as ecological inefficient nodes, indicating that the ecological pressure index is the largest at this time point and exceeds the sum of the ecological health index and the ecological resilience index, that is, the increase in human activities leads to the reduction of biodiversity and vegetation cover, reducing the health and resilience of the ecosystem. In this case, the ecological environment of the island is relatively poor.

[0150] Based on the above evaluation system for the ecological environment of an island, the present invention also provides an evaluation method for the ecological environment of an island, including the following steps:

[0151] Step 1: Construct a planar display diagram of the island, and collect sub-region environmental data and block collection time;

[0152] Step 2: Select the types of sub-region environmental data to obtain ecological measurement indicators;

[0153] Step 3: Perform state transformation on the ecological measurement indicators to obtain ecological measurement coefficients, set multiple transformation bases, and perform multivariate analysis on the ecological measurement coefficients according to the multiple transformation bases to obtain ecological impact bases;

[0154] Step 4: Allocate the ecological impact bases according to the island application blocks to obtain an impact ratio display diagram, perform area accumulation on the impact ratio display diagram to obtain a comprehensive area base, set an observation period to perform characteristic number graph transformation on the comprehensive area base to obtain an impact base value dynamic diagram, perform endpoint aggregation on the impact base value dynamic diagram through area sampling nodes to obtain endpoint base values, and perform ecological evaluation according to the endpoint base values to obtain ecological optimal nodes and ecological inefficient nodes.
