Study on Comprehensive Disaster Bearing Capacity Evaluation of Flood Disaster in Henan Province Based on Combination Weighting
In order to improve the flood disaster prevention and mitigation capacity,taking Henan Province as the study area,the paper built a comprehensive flood disaster bearing capacity evaluation index system covering disaster prevention capacity,disaster resistance capacity,disaster relief capacity and recovery capacity,and assessed the comprehensive flood disaster bearing capacity of Henan Province by using AHP-entropy combination assignment method and comprehensive evaluation index model.The results show that a)the comprehensive flood disaster bearing capacity of Henan Province shows certain regular changes,and the distribution characteristics of comprehensive disaster bearing capacity and disaster relief capacity are basically the same,overall the central region＞southwest region＞northeast region＞east re-gion＞southeast region≥northwest region.South region has the strongest disaster prevention capacity,while the north and central regions have weaker disaster prevention capacity;cities in the southwest-northeast regions have stronger disaster resilience,while cities in the north-west-southeast regions are weaker;recovery capacity basically decreases from northwest to southeast.The area with medium and above com-prehensive disaster-bearing capacity accounts for 66.67%of the total area,and the area with lower medium capacity accounts for 33.33%of the total area.b)In terms of the disaster-bearing capacity of each city(pilot area),Xinyang City has the strongest disaster prevention capac-ity and the pilot area of Jiyuan has the weakest disaster prevention capacity and disaster relief capacity.Zhengzhou City has the strongest dis-aster prevention capacity,disaster relief capacity and recovery capacity,and Sanmenxia City has the weakest disaster relief capacity.Zhuma-dian City has the weakest recovery capacity.The comprehensive disaster bearing capacity of flood disaster in Henan Province is at a medium and low level on the whole,so it is necessary to formulate reasonable strategies to improve the comprehensive disaster bearing capacity of flood disaster.
