摘　　要：海岛作为海洋经济开发的桥头堡,是国家实施海洋战略的重要载体。我国海岛多处亚欧大陆和太平洋相交的地震活跃带,而地震工程在海岛领域发展较为薄弱。本文从暴露度、敏感性和应对恢复能力三个方面建立由20项指标构成的海岛地震灾害社会脆弱性综合评价体系,以我国的舟山群岛为研究对象,利用熵权法和改进的TOPSIS模型对其下辖的定海区、普陀区、岱山县、嵊泗县四个海岛县区进行分析,计算出各海岛县区的评价值与理想解之间的相对贴近度,从而得出四个海岛县区地震灾害社会脆弱性的高低,依次为岱山县、普陀区、嵊泗县、定海区。本研究建立的评价体系为定量化分析海岛地震灾害的社会脆弱性提供了研究思路,对海岛防震规划和减灾策略具有指导意义。As a bridgehead for the development of marine economy,the island is an important carrier for the national implementation of the marine strategy.Many islands in China are located in the seismically active zone where the Eurasian continent and the Pacific Ocean intersect.However,seismic engineering develops weakly in this field.A comprehensive index system including 20 indicators from three aspects of exposure,sensitivity and resilience was established to evaluate social vulnerability of island seismic disaster.Taking the Zhoushan islands as the study objects,the entropy weight method and the improved TOPSIS model were selected to finish the analysis and calculation about the four island counties,i.e.Dinghai,Putuo,Daishan and Shengsi,aiming at figuring out the relative closeness between evaluative value and ideal solutions and ranking the social vulnerability of the four island counties.The result shows four island counties social vulnerability of island counties seismic disaster,ranking as Daishan,Putuo,Shengsi,Dinghai.The evaluation system established in this study provides research ideas for the quantitative analysis of the social vulnerability of island seismic disaster,and provides instructive significance for island seismic disaster prevention planning and disaster mitigation strategy.
