摘要：This study proposed a method for micro-scale landform analysis using large-scale digital terrain model (DEM), which was derived from airborne LIDAR data. Other than common topography and watershed analysis using DEM, new method of cross-section curve analysis was developed and tested in this study, which aims to extract convex break and concave break points on the surface of large- scale of DEM. With extracted convex slope break lines and concave slope break lines, micro-scale landform units of study area, including crest slope, the upper side-slope, lower side-slope, head hollow, foot slope and channel-way, etc., were identified and classified successfully, which proved adaptation of the proposed method for micro-scale landform analysis over a large extent
