| 摘要: |
| 对1979-1996年登陆广东省的热带气旋灾害进行了分析,并采用模糊数学方法提出了灾害评估模型,计算出历次登陆热带气旋的综合灾害指数,根据指数进行分级(5级),得到轻重不同的灾害判据。结果表明,综合灾情指数基本能反映经济损失的大小,可见该模型是可行的。 |

| Abstract: |
| In this peper,data from Disaster Reduction in China,have been used to statistically analysethe disaster by tropical cyclones that occurred from 1979 to 1996 within the area of GuangdongProvince. By the method of Fuzzy Subsets Theory,the conditions of the disaster have been disscussed and the evaluation model of the disaster is set up. The index of the disaster of every tropicalcyclone have been obtained,and have been divided into five parts. The result shows that the indexis almost Proportional to the direct economic loss, so this model is feasible. |
