摘　　要： 采用1990～2007年的台风相关资料，建立中国东南沿海地区台风灾害数据库，分析了台风强度、台风路径及台风致灾因子频次分布；最终选取由台风引起的大风、24h雨量、风暴潮及受灾次数等为评价指标。计算出台风灾害灾次指数TZC,编制了1990～2007年东南沿海地区台风灾害危险性评价图。结果表明：浙江南部沿海，福建、广东大部分地区受台风影响较多，而浙江北部、内陆地区及上海受影响较小，这与台风登陆的强度和频次有密切关系；TZC高危险区和次高危险区分布在浙江台州以南的沿海区域，TZC小于4．0的低危险区分布在浙江、福建及广东省的内陆地区，TZC空间递变表现出从沿海向内陆减少的趋势。 Based on the data of typhoons in 1990 - 2007, we establish database on typhoon disaster in southeast areas of China and analyze the intensity, movement path and distribution of typhoon hazard factors. We selected the typhoon induced strong wind, a 24 - hour rainfall, storm surge and disaster number as evaluation indicators, and calculated the disaster sub - index and compiled the hazard distribution map of typhoon disaster in southeastern coastal areas during 1990 -2007. The results show that south coastal areas of Zhejiang and Fujian Provinces and most parts of Guangdong Province are most affected, while north Zhejiang Province, inland areas and Shanghai are less affected, which are closely related to the intensity and frequency of typhoon landfall. The most dangerous areas are the coastal areas to the south of Taizhou City, Zhejiang Province and the less dangerous areas are the inland areas of Zhejiang, Fujian and Guangdong Provinces. The sub - index is decreasing from coastal areas to in/and areas.
