Abstract

The embodiment of the invention discloses a coastal wetland ecological vulnerability potential risk comprehensive evaluation method. The method comprises the following steps: S1, establishing a coastal wetland ecological vulnerability potential risk comprehensive evaluation index system; S2, determining the weight of each evaluation index of the index system by adopting a CRITIC weighting method;and S3, comprehensively evaluating and sequencing the ecological vulnerability potential risks of different coastal wetlands by adopting a TOPSIS method. Potential ecological risks of coastal wetlandecological vulnerability can be comprehensively and scientifically reflected, and technical support is provided for protection and management of coastal wetland ecological vulnerability.

Description

technical field [0001] The invention belongs to the technical field of wetland ecological environment protection, and in particular relates to a method for comprehensively evaluating potential risks of coastal wetland ecological fragility. Background technique [0002] Ecological vulnerability refers to the variability of the ecological environment driven by nature or human activities in a specific spatial area. This change is often in a direction that is not conducive to human survival, development, and utilization. It has nothing to do with the ecological environment. corresponding to the stability. The potential uncertainties shown by ecological fragility may have an effect on the ecosystem and its components, and the results of these effects may lead to damage to the structure and function of the ecosystem, thereby endangering the safety and health of the ecosystem, so coastal wetlands are ecologically fragile Permanent monitoring and evaluation is the basis for researc...
