Sensitivity Assessment on Flood Hazards Environment of Traditional Villages in Central Henan
In order to effectively evaluate the flood sensitivity of traditional villages and improve the ability of disaster risk prevention,taking the traditional villages in central Henan as the research object,based on the theory of disasters,the GIS platform was used to draw the geo-graphic information map,and the entropy weight method(EWM)and the AHP-EWM were used to calculate the index evaluation weight,and weighted data overlay analysis was used to obtain village sensitivity zoning charts.The results show that the flood disaster environment of traditional villages in central Henan is mainly of medium sensitivity,two-thirds of traditional villages are in the middle and low sensitive lay-ers,and the structure presents a rugby shape of"large in the middle and small at both ends".In terms of spatial distribution,traditional vil-lages with low and medium sensitivity risks are mainly distributed in high-altitude and far water areas.There are 7 high-sensitivity traditional villages,including Majie,Daying and Zhaiji in Baofeng County of Pingdingshan City,Zhifang and Xiaozhangzhuang villages in Jiaxian Coun-ty,Peicheng Village in Yancheng District of Luohe City and Pacun Village in Yuzhou of Xuchang City.
