中文摘要:

评价方法的合理选择是获取正确滑坡地质灾害易发性评价结果的关键环节。本文以贵州省黔西南州普安县为例，在全面分析区内地层岩性、地形地貌、地质构造和水文地质等条件对滑坡灾害影响的基础上，采用层次分析法建立了具有针对性的滑坡灾害易发性评价指标体系，并开展了实际应用。评价结果在县境内划分出了极高、高、中和低易发区四个区域，对比分析显示评价结果与区内滑坡灾害发育宏观认识与实际分布情况吻合较好，证明了该方法在山区滑坡地质灾害易发性评价中的有效性与实用性。

英文摘要:

The reasonable selection of assessment methods is the key to obtaining the correct susceptibility mapping results of landslide geological hazardsIn this paper，it taken Pu’an County of Qianxinan Prefecture in Guizhou Province as an example，based on the analysis of the impact of stratum lithologies，landforms，geological structures，and hydrogeological conditions on landslide hazards in the area，the Analytical hierarchy process is used to establish the evaluation index system of landslide disaster susceptibilityThe practical application is carried out accordinglyThe assessment results showed that the area’s susceptibility mapping of landslide hazards is divided into four levels，which agrees with the actual landslide hazard developmentsIt proves the effectiveness and practicability of the Analytical hierarchy process in the susceptibility assessment of landslide geological hazards in the mountain areas.
