Risk Assessment on Earthquake Disaster Social Vulnerability Based on Improved Catastrophe Progression Method---A Case Study on Sichuan Earthquake Disaster
摘要
Abstract
For the subjectivity of index weight assignment in the social vulnerability assessment in earthquake disaster,and traditional catastrophe progression evaluation method has the defects of the evaluation of the number of indicators.Firstly,the risk assessment index system of the social vulnerability assessment of earthquake disaster based on catastrophe progression method is established,and rough set attribute reduction method is adopted to im-prove catastrophe progression method,then using catastrophe progression method to comprehensively evaluate the social vulnerability to earthquake disaster,and finally,take earthquake disaster in Sichuan Province as an exam-ple,through the analysis of the results of the social vulnerability risk assessment in Sichuan province,the risk re-sponse recommendations is proposed.关键词
