陕西省域洪涝灾害应急响应能力评价OA

Flood disasters pose an increasingly severe challenge to urban system safety with rapid eco-nomic development and the frequent occurrence of extreme climate events.To scientifically evaluate and improve emergency response capabilities for flood disasters,this study first analyzed the formation mechanisms of flood disasters and,based on PSR theory,constructed a multidimensional evaluation sys-tem comprising 3 secondary indicators,8 tertiary indicators,and 21 quaternary indicators.Ten prefec-ture-level cities in Shaanxi Province were selected as empirical objects,and official data from 2019 to 2023 were collected for quantitative evaluation.Second,the entropy weight method and coefficient of variation method were jointly used to determine indicator weights,and a comprehensive scoring model was constructed based on the weighted summation method.The spatial distribution,dimension propor-tions,and temporal evolution of emergency response capability were mapped to obtain the evaluation grades of flood disaster emergency response capability for each prefecture-level city.Finally,improve-ment pathways were proposed based on the analysis results.The results show that there are significant differences in flood disaster emergency response capability among cities in Shaanxi Province.Xi'an scored the highest at 0.570 4,followed by Yulin with 0.463 1.Cities such as Hanzhong and Weinan in southern Shaanxi still need improvement.Tongchuan performs well in post-disaster recovery,whereas cities such as Shangluo need improvement in early-warning information services.The model provides a scientific basis for flood disaster emergency management,helping reduce disaster losses and safeguard people's lives and property.
