【摘要】 以舟山市为研究对象,从自然和社会两个方面出发进行脆弱性评估。选择土地利用类型为指标进行自然脆弱性评估;选取人口房屋密度、城镇化率、区域疏散度等9个指标,采用SDSVI指数与AHP决策分析法进行社会脆弱性评估,其中SDSVI指数是参考沿海脆弱性指数CVI构建的风暴潮承灾体社会脆弱性指数。在此基础上,对综合脆弱性评估进行分析与探究。结果显示,脆弱性由高到低依次为:岱山县、嵊泗县、普陀区、定海区。研究结果可为政府应对风暴潮灾害以及进一步开展相应的风暴潮灾害风险评估工作等提供科学参考。更多还原

【Abstract】 Taken Zhoushan City as the research object, storm surge vulnerability assessment in physical and social aspects is completed. For the nature aspect, vulnerability is ranked based on land use types. As for social vulnerability assessment, nine indexes are selected such as population-building density, urbanization rate and the degree of regional evacuation, the methods are AHP decision analysis method and SDSVI index. SDSVI index which means Storm Surge Disaster’s Social Vulnerability Index is built according to the assessment method of Coastal Vulnerability Index(CVI). On this basis, we try to explore the comprehensive vulnerability assessment.The results show that the vulnerability in sequence from high to low is Daishan County, Shengsi County, Putuo County, Dinghai County. The results can be provided for the government’s response to the storm surge disaster and the further study.更多还原
