陕西省暴雨洪涝灾害防灾减灾能力的评估

Evaluation on Disaster Prevention and Mitigation Ability of Rainstorm and Flood Disaster in Shaanxi Province

基于防灾减灾理论及框架,采用层次分析法、熵值法和组合赋权法计算出指标体系的权重,计算陕西省暴雨灾害防灾减灾能力综合指数,对陕西省10个地级市的防灾减灾能力进行评估。结果显示:西安市的防灾减灾能力最强,其次为咸阳市、宝鸡市、铜川市、渭南市、延安市、榆林市,最后为汉中市、商洛市、安康市。分析得出,关中地区的暴雨洪涝灾害防灾减灾能力最强,陕北地区次之,陕南地区防灾减灾能力较弱。

Based on the theory and framework of disaster prevention and mitigation,the weight of the index system was obtained by using the analytic hierarchy process,the entropy method and the combined weighting method,and the comprehensive index of the disaster prevention and mitigation ability of rainstorm disasters in Shaanxi Province was calculated.Assessment of disaster mitigation capabilities.The results show that the disaster prevention and mitigation capacity of Xi’an was the highest,followed by Xianyang,Baoji,Tongchuan,Weinan,Yan’an,Yulin,and the last are Hanzhong,Shangluo,and Ankang.The analysis shows that the disaster prevention and mitigation ability of rainstorm and flood disasters in Guanzhong area was the highest,followed by northern Shaanxi,and the ability of disaster prevention and mitigation in southern Shaanxi was lower.
