摘要: 以重庆万州区为例,以城镇为行政单元,综合考虑地质灾害、孕灾环境、公路类型、路网技术等级和路网密度 等指标,基于GIS 软件和AHP 集成方法得到了重庆市万州区的公路网洪灾危险性分区图。结合综合评估指数将重 庆万州区公路网洪灾危险等级分为2 级,即中低危险性和较高危险性,所占区域总面积比例分别为68. 55% 和 31. 45%。

Abstract: In Wanzhou area of Chongqing,the town was taken as the administrative unit. With the consideration of the geological hazards,hazards inducing environment,highway type,highway network technical grade and highway network density indexes,the zoning map of highway network flood risk in Wanzhou area of Chongqing based on GIS software and AHP integration method was obtained. Combining with the comprehensive evaluation indexes,the highway network flood risk grade was divided into two grades,namely moderate risk and high risk. The proportions of these two risk level areas were 68. 55 percent and 31. 45 percent separately.

Key words: highway network flood, risk assessment, GIS technology
