基于模糊数学方法的海岛地质灾害风险评价--以长兴岛为例

Risk assessment of geological hazard based on fuzzy mathematics--A case study of Changxing island

  • 摘要: 基于海岛地质灾害风险评价指标体系,采用模糊数学法,以长兴岛为例,对地质灾害风险进行综合评价。评价结果表明:长兴岛的高风险区域面积占全岛面积的9.95%,中风险区占14.00%,低风险区为76.05%。高、中风险区除了大片的集中分布外,还呈现出斑块状零散分布,这主要是长兴岛地质环境地域性与社会因素差异性结合的结果。

     

    Abstract: Base on the geological hazard risk assessment index system of the island, make full use of fuzzy mathematics method, we have evaluated the geological hazard risk of Changxing island. The result showed that the high-risk area is 9.95%, the risk area is 14.00% and low-risking area is 76.05%. In addition to the large centralized distribution of the high-risk area and the risk area, it also showed that Changxing island had a patchy distribution around the coastal zone of the island, which cause by the combination of different natural geological environment and socio-economic factors in Changxing island.
