摘　　要：为了反映岩溶对公路建设影响的区域性特点,选择贵州省开展公路工程岩溶环境区划工作,提出了岩溶地区公路工程岩溶环境区划的原则和指标体系、建立了评价模型。运用层次分析法和GIS技术,绘出了岩溶对公路影响程度分区图。将贵州省划分为4个影响区,即西部以高～中影响为主的地区、东北部以中～高影响为主的地区、中部以中等影响为主的地区和低影响区。通过对贵州省公路路网和评价结果的综合分析,在12462km省道以上公路中,大约有6265km公路处于高影响区,而在1587km已建和在建高速公路中,有567km处于高影响区,将对贵州公路规划、建设、养护与管理起到很好的指导作用。In order to reflect zone characteristics ofkarst for highway construction, the authors proposes principle and index system and establish evaluation model for karst environmental zoning for highway engineering on the basis of case study in Guizhou Province. Meanwhile, the zoning map of karst for highway is made with the analytic hierarchy process （AHP） and GIS technology. It divides Guizhou Province into four influenced zones, namely, western region as the high-median influenced zone, northeastern region as the median-high influenced zone, central region as median influenced zone and low influenced zone. After comprehensively analyzing highway network and evaluation results, it is found that 6 265 km of 12 462 km long provincial highways are located in high influenced zone while 567 km of 1 587 km long expressways completed and in progress are also located in high influenced zone The zoning results could be used as guidelines for highway planning, construction and management in Guizhou Province.
