A Pre-evaluation Model for Typhoon Disasters in China
摘要
Abstract
In order to establish a collection, 34 typhoons with complete disaster record occurred from 2000 to 2008 are arranged.A model for pre-evaluation of losses from typhoon disasters is established on the basis of fuzzy mathematical method.Choosing 8 effective factors as input indexes of the model, and determining impact factor weights by analytic hierarchy process, composite evaluation indexes of each typhoon in the collection are calculated,which are then fitted with typical index of disaster loss as affected population, afflicted crop amount and direct economic losses etc.The optimal power function regression equation is obtained by properly adjusting impact factor weights to realize quantitative pre-evaluation of typhoon disasters.关键词
