摘　　要：针对在滑坡灾害易发性评价研究中,评价因子相互干扰且较少考虑各因子对滑坡灾害贡献率的问题,本文选取证据权模型为评价方法,构建以高程、坡度、坡向、剖面曲率、平面曲率、岩性、距断裂距离、植被指数、距水系距离、距道路距离、土地利用类型及降水量共12个因子为指标的评价体系,对普洱市进行了滑坡灾害易发性评价。评价精度较高,可为类似滑坡灾害易发性评价提供参考。The assessment of landslide susceptibility is a crucial part of risk evaluation and serves as a significant scientific basis for disaster prevention and reduction efforts.In addressing issues within landslide susceptibility studies,where factors interfere with each other and the contribution rates of these factors to landslide disasters are often overlooked,this paper employs the evidence weight model as an assessment method.It establishes an evaluation system with 12 indicators,including elevation,slope,aspect,profile curvature,plan curvature,lithology,distance to faults,vegetation index,distance to water bodies,distance to roads,land use type,and precipitation,to assess the susceptibility of landslide disasters in Pu'er City.The evaluation accuracy is relatively high and can serve as a reference for similar landslide susceptibility assessments.
