摘要
为有效评估传统村落洪涝灾害敏感性,提升灾害风险防范能力,以豫中地区传统村落为研究对象,基于灾害学理论,借助GIS平台绘制地理信息图,结合熵权法、AHP-熵权法计算评估指标权重,并利用加权栅格数据叠加分析,获取村落敏感性区划图表.结果表明:豫中地区传统村落洪涝灾害环境以中度敏感为主,三分之二的传统村落处于中低敏感水平,结构上呈现"中间大、两端小"的橄榄球形;空间分布上,中低敏感水平的传统村落主要分布在高海拔远河区域;熵权法和AHP-熵权法评估共同高敏感性传统村落有 7 个,即平顶山市宝丰县马街村、大营村、翟集村,郏县纸坊村、小张庄村,漯河市郾城区裴城村和许昌市禹州市扒村.
Abstract
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.
