| 摘 要： | 针对重庆市万州区公路洪灾,选择公路沿线地质灾害发育、暴雨强度、洪水频次、地貌条件、岩性条件、年均降雨量、植被覆盖度与地质构造等8个孕灾环境指标,通过层次分析法确定其权重,提出了孕灾环境指数评价模型.在GIS技术支持下,以网格为单位提取出各网格的孕灾环境指数,据此结合万州区乡镇级行政区划将万州区公路洪灾孕灾环境划分为4个...

| Abstract: | For the road flood in Wanzhou area in Chongqing,eight geological hazards developing environment indexes,i.e.geological hazards along the highway,rainstorm,flood frequency,landforms,Geological lithology,average annual rainfall,vegetation coverage and geological conditions are selected.And then evaluation model is proposed and each index is calculated through Analytical Hierarchy Process(AHP).Based on MAPGIS technology,indexes of each grid are extracted,combining with Wanzhou administrative region,environment... |
