摘　　要：“三江”(即金沙江、澜沧江及怒江)地区自然条件恶劣,交通不便,解决该地区水电大开发地质灾害调查中一条切实可行的方法是利用遥感。论文分析了金沙江干热河谷气候环境和地形条件的特点及他们对滑坡解译产生的影响。通过研究这一地区的滑坡在多种遥感影像上的图斑特征配合实地考察,分析并列举了干扰滑坡识别的图斑,总结出该地区的古滑坡、活动滑坡和典型滑坡的识别特征。同时对该地区滑坡不发育,所占地质灾害比例低的现象进行了分析。指出当地气候、地形、构造特征、岩土类型对滑坡发育存在的影响。为该类型地区的遥感地质调查提供借鉴。It is important to use remote sensing technique to investigate geological hazard in “Sanjiang”（three rivers） region, because natural and traffic conditions there are terrible. In this paper, the authors discussed the climate and topographic features in this area ,and their effects to landslide interpretation. By the study of multi-images and the site investigation in region, the authors find the fake image information and conclude image features about landslide. Features of ancient landslides, active landslides and typical landslides are discussed in detail, and their images were presented. In addition, the authors analyze the reasons for the low occurrence of landslides in this region, including four factors （climate, topography, structure features and rock types） contributing to landslide occurrence in the region.
