摘　　要：以白水江流域为研究区,选取DEM、Slope、Aspect等14个滑坡灾害影响因子,运用地理探测器方法对该区域滑坡灾害影响因素进行了探测。结果表明:(1)通过分异与因子探测器得到DEM、年降水量、土壤类型、地表覆盖类型、地震动峰值加速度、道路密度对滑坡灾害有较强的解释程度,对滑坡灾害的稳定性影响显著,其他因子对滑坡灾害解释力较弱;(2)通过交互作用探测器得该区域滑坡灾害影响因子表现为非线性增强和双因子增强,滑坡灾害的稳定性是多个影响因子共同作用的结果;(3)白水江流域滑坡灾害受地形地貌、区域降水量、地质构造、地震、人类活动、土壤植被多个影响因子的影响,导致滑坡灾害空间分布存在显著的差异。Taking Baishuijiang River basin as the study area,14 landslide hazard influencing factors,such as DEM,Slope and Aspect,are selected to detect the landslide hazard influencing factors in this area by using the geographical detector method.The results show that:(1)DEM,annual precipitation,soil type,surface coverage type,peak acceleration of ground motion,and road density obtained by differentiation and factor detector have a strong degree of interpretation of landslide hazards,and have a significant impact on the stability of landslide hazards,while other factors have a weak interpretation of landslide hazards;(2)Through the interaction detector,the influence factors of landslide disaster in this area are nonlinear and double factor enhancement,and the stability of landslide disaster is the result of the joint action of multiple influence factors;(3)The landslide disaster in Baishuijiang River basin is affected by many factors,such as topography,regional precipitation,geological structure,earthquake,human activities,and soil vegetation,resulting in significant differences in the spatial distribution of landslide disasters.
