根据1949～1999年共50年资料，对影响我国的热带气旋所造成的灾情特点作了评估研究。采用数理统计方法，进行定量的计算，按登陆和外围影响两类主要方式建立灾情指数序列，并在此基础上，客观地划分了灾情等级，用来表示受灾的程度。还采用独立于本资料源的Suffir-Simpson热带气旋灾害指数评估方法和资料进行对比验证。最后提出了一套台风灾害预评估的技术方法。%The disaster characteristics for East China caused by tropical cyclones in 1949-1999 were analyzed. By using numerical statistical analysis and quantitative calculation, the disaster index was built along separate routes. And on this base ,objective damage assessment for TC was also given. A contrast testing with Suffir-Simpson index of TC was made using an independent data set. Finally, an assessment method for tropical cyclone disasters was given.
