Problems solved by technology

[0002] In the field of environmental monitoring, it is necessary to evaluate the islands located on the sea from time to time. The most important item in the evaluation is the vulnerability of the island, which is related to the lifespan of the island. protection, therefore, the vulnerability assessment of islands is extremely important, but the assessment of the vulnerability of islands in the prior art only considers the impact of natural disasters and seawater erosion on the vulnerability of islands. However, during the research process, it was found that the vulnerability of islands Therefore, it is necessary to study a method for assessing island vulnerability that considers various factors to improve the accuracy of island vulnerability assessment

Abstract

The invention discloses an island ecological vulnerability evaluation method. The method comprises the following steps: S1, evaluating and calculating ecological exposure degree of the island, whereinthe ecological exposure degree of the island comprises natural pressure B1 and artificial interference B2; s2, evaluating and calculating the ecological sensitivity of the island, wherein the islandecological sensitivity comprises an ecological condition B3, an environmental condition B4 and an important habitat B5; s3, evaluating and calculating the ecological fitness of the island, wherein theisland ecological adaptability comprises a self-adjusting capability B6, a social support condition B7, an environmental protection B8 and a comprehensive management level B9; and S4, performing evaluation calculation on the island ecological vulnerability according to the island ecological exposure degree evaluation result obtained in the step S1, the island ecological sensitivity evaluation result obtained in the step S2 and the island ecological fitness evaluation result obtained in the step S3 to obtain an island ecological vulnerability evaluation result.
