| 摘 要： | 本文对１９４９～１９９７年登陆中国的３４２个热带气旋进行了统计，并选取１９９０～１９９７年的４１个热带气旋所造成的灾害进行了分析，采用模糊数学方法提出了灾害评估模型。首先根据有关因子计算出历次登陆热带气旋的综合灾情指数，并在此基础上客观地划分５个灾情等级，用来表示受灾的程度。结果表明，该方法可以较好地评价不同强度的登陆热带气旋可能造成经济损失的大小。

| Abstract: | In this paper,342 tropical cyclones that occurred from 1949 to1997 within the area of China have been applied to statistic study.The fuzzy Subsets method was used to evaluate the damage caused by 41 tropical cyclones during the period of 1990 to 1997.At first,the index of the disaster of every tyopical cyclone has been gotten.Then based on the index,five grades have been divided objectively,which distinguished the loss levels.The result shows that this method can relatively evaluate the economic losses caused by tropical cyclones with different density. |
