Risk Assessment of Flooding in Jiangxi Province Based on Fuzzy Comprehensive Evaluation
Based on the theory of natural disaster risk system,the formation mechanism of flood disaster is explored,and the risk assessment index system of flood disaster in Jiangxi Province is constructed from the four risk elements of flood hazard,sensitivity,vulnerability and disaster prevention and mitigation capacity.The results of flood risk assessment and risk zoning map of the study area were finally obtained.The results show that the high-risk areas of flooding in Jiangxi Province are mainly located in the Poyang Lake Plain in northern Ganxi,the transition zone of the hilly plain in eastern Ganxi and the river valley basin area in northeastern Jiangxi;while the western,northwestern and southern Jiangxi Province are generally low-risk areas of flooding,except for a few scattered areas with high risk.By verifying the assessment results through existing plans and historical flood events,the flood risk assessment results obtained in this paper are more consistent with historical facts in Jiangxi Province and can provide reference for flood risk management in the same type of provinces.
