Urban Flood Resilience Evaluation Algorithm Based on Socio-Economic Indicators:A Case Study of Huangkeyuan,Zhengzhou City
In order to cope with urban floods that exceed the standard,it is necessary to carry out urban flood resilience construc-tion.However,the lack of a reasonable and effective evaluation algorithm for urban flood resilience has become a bottleneck re-stricting.This study proposed an urban flood resilience evaluation algorithm based on the socio-economic situation,using the fac-tors of vulnerable populations,vehicles,and power grids.A case study was given in Huangkeyuan Jinshui District,Zhenzhou city.The results show that the lowest level of urban flood resilience in the research area occurs in the 32nd hour of flood duration;And after implementing urban flood resilience measures,the urban flood resilience was increased from 0.58 to 0.65 under the same intensity of floods,effectively improving urban flood resilience and shortening the time process for urban normal function res-toration.This set of urban flood resilience construction evaluation algorithms can support the basic theory of urban flood resilience and the quantification of urban flood resilience levels.
