文章在采用相对高差和坡度将公路地貌划分为平原区和山区的基础上，将山区公路洪水灾害分为山区沿河公路水毁和山区公路边坡水毁；采用模糊综合评价法和专家调查法建立了危险性评价模型，构建了危险性评价指标体系和各指标权重；依托ArcGIS10.0软件开展了山区公路洪水灾害综合危险性评价，完成了山区公路洪水灾害危险性区划。结果显示：山区公路洪水灾害综合危险度值为[1.24，7.52]；全国可划分为微度危险、中度危险、重度危险和极重危险4级；区划方案与山区公路洪水灾害实际分布状况相符。
文章在採用相對高差和坡度將公路地貌劃分為平原區和山區的基礎上，將山區公路洪水災害分為山區沿河公路水燬和山區公路邊坡水燬；採用模糊綜閤評價法和專傢調查法建立瞭危險性評價模型，構建瞭危險性評價指標體繫和各指標權重；依託ArcGIS10.0軟件開展瞭山區公路洪水災害綜閤危險性評價，完成瞭山區公路洪水災害危險性區劃。結果顯示：山區公路洪水災害綜閤危險度值為[1.24，7.52]；全國可劃分為微度危險、中度危險、重度危險和極重危險4級；區劃方案與山區公路洪水災害實際分佈狀況相符。

Based on distributing highway landform into plain areas and mountainous areas by relative elevation and slope ,the types of highway flood disasters in mountainous areas are divided into highway flood disaster a‐long river and highway slope flood disaster .The risk assessment model is established by using fuzzy compre‐hensive assessment method and expert grading method ,and the assessment indicator system as well as their weights is also established .The risk assessment on highway flood disasters in mountainous areas is conducted by ArcGIS10.0 software and the risk regionalization is made .The results show that the comprehensive risk index of highway flood disasters in mountainous areas ranges from 1.24 to 7.52;the mountainous areas are divided into micro risk areas ,moderate risk areas ,severe risk areas and extremely severe risk areas ;and the regionalization scheme is coincident with the distribution of highway flood disasters in mountainous areas .
