摘　　要：为了解决高陡边坡调查困难、效率低等问题,本文运用高分辨率遥感影像和ASTER GDEM数据,根据遥感影像纹理特征和地形信息,对研究区域高陡边坡进行人机交互解译,获取高陡边坡坡体范围;以数字高程模型为基础,运用地形分析方法快速提取坡体几何特征,并结合纵剖面反映坡面几何形态,为相关部门进行高陡边坡调查和数字化边坡构建提供参考。In order to solve the problems of difficult investigation and low efficiency of high steep slope,this paper uses high resolution remote sensing image and ASTER GDEM data,and carries out human computer interactive interpretation of high steep slope in the study area based on the texture characteristics and terrain information of remote sensing image,so as to obtain the range of high steep slope body.Based on the digital elevation model,the topographic analysis method is used to quickly extract the geometric features of the slope,and the geometric form of the slope is reflected in combination with the longitudinal section,which provides reference for the relevant departments to investigate the high steep slope and build the digital slope.
