| Abstract: | In this paper, data from Disaster Reduction in China have been used to statistically analyze the disaster by tropical cyclones that occurred from 1979 to 1996 within the area of Guangdong province. By the method of fuzzy subset theory, the conditions of the disaster have been discussed and the evaluation model of the disaster B set up. The index of the disaster of every tropical cyclone have been obtained and divided into five parts. The result shows that the index is almost proportional to the direct economic losses, so this model is reasonable. |
