In order to research the degree of social economic damage caused by tropical cyclones(TC) landing in Zhejiang Province and improve the service level of typhoon prevention and disaster reduction,this paper evaluates the disaster influence of TC occurred in Zhejiang Province from 1981 to 2007 by the fuzzy comprehensive evaluation method.In order to verify that the disaster effect assessment model is correct or not,the actual disaster situation of TC is evaluated,and the disaster influence index and the disaster index of TC are calculated and graded.Results show that the concordance rates between the disaster index and the disaster influence index can reach 92% for all samples.In addition,the correlation coefficient between the disaster influence index and the corresponding direct economic losses is 0.79.It indicates that the disaster effect assessment model can evaluate disaster influence of TC landing in Zhejiang Province.
