Abstract
Based on the theory of natural disaster risk,this paper fully considers the socio-economic conditions,natural environment,disaster prevention and mitigation capabilities,and the vulnerability,sensitivity and danger of flood disaster risk,and comprehensively applies GIS technology,combined weighting method and fuzzy synthesis method to establish a zoning model of rainstorm and flood disaster risk in Benxi City,and conducts corresponding zoning analysis.The results showed that Benxi County,Xihu District and Huanren County belonged to the high-risk areas of flood disasters,Pingshan District and Mingshan District were low-risk and low-risk areas,respectively,and Nanfen District was a medium-risk area.There was a good correlation between the rainstorm and flood risk index and the disaster level index,with a correlation coefficient of 0.8106,and reached a significant correlation level.关键词
