基于改进熵值法的台风灾害风险趋势评估
Trend Assessment of Typhoon Disasters Based on the Improved Entropy Method
摘要
Abstract
Based on the statistical typhoon disaster data of Guangdong,Fujian,Shanghai,Jiangsu,Zhejiang,Shandong,and Guangxi provinces in the southeast coastal areas during 1990-2010,an entropy method improved by standardized transformation is used to calculate the risk assessment index of each year.Then,we use the cluster analysis to classify the comprehensive index and to analyze its change trend.Results show that the largest weight of the indicators is the collapsed houses,followed are deaths,affected area and direct economic loss;the comprehensive index of the risk assessment is larger in 1990-1997 than in 1998-2010,and the former is mainly influenced by the collapsed houses and the deaths,while the latter is influenced by the affected area and the direct economic loss;Both 1994 and 1996 are huge disaster years,and most other years are between the middle and small.关键词
