摘　　要：采用1990～2009年风暴潮灾害损失数据,选择中国东部沿海地区11个省市为研究对象,借鉴沿海脆弱性指数(Coastal Vulnerability Index,CVI)方法的评估思路,构建风暴潮灾害脆弱性指数SSVI(Storm Surge Vulnerabil-ity Index,SSVI),采用加法模型评价中国沿海省区风暴潮灾害的物理脆弱性。结果表明:沿海地区风暴潮脆弱性存在较大年际变化;高和很高脆弱性等级主要分布于东南沿海各省区,低和很低脆弱性等级主要分别于北部沿海各省区,而中等脆弱性等级空间分布则变化较大。Firstly,the storm surge disaster vulnerability index（Storm Surge Vulnerability Index,SSVI） is built by learning form the assessment method of Coastal Vulnerability Index（Coastal Vulnerability Index,CVI）.Then,physical vulnerability of storm surge is assessed using additive model,according to the storm surge disaster loss data during 1990 to 2009 of eleven provinces in the coastal region,which are Liaoning Province,Hebei Province,Tianjin City,Shandong Province,Jiangsu Province,Shanghai City,Zhejiang Province,Fujian Province,Guangdong Province,Guangxi Zhuang Autonomous Region and Hainan Province.The results show that there is a large inter-annual variation of the vulnerability of coastal storm surges;the high and very high level of physical vulnerability are mainly distributed in southeastern coastal provinces,the low and very low level,in northern coastal provinces,respectively,while distribution of the middle level changes greatly.
