Abstract:
The disaster impact is tentatively evaluated for typhoons making landfall in Chi na. Ten factors are chosen as disaster impact factors, and weighted values of th ese impact factors are calculated by using weighted average programming method. T hen, the evaluation coefficient of typhoon impact and the corresponding disaster grade can be obtained by applying the fuzzy synthetic method. Evaluation tests have been carried out for landed typhoons during the years from 2000 to 2006. Th e results show that the model evaluation grade keeps in close agreement with the actual disaste r grade. The percentage of accuracy can reach 89%, 87%, 73%, and 78% , respectiv ely, for four disaster grades as especial great, great, heavy, and general, and about 90% for all samples. The results indicate that this model can evaluate ty phoon disaster well for typhoons making landfall in China.
