The extensive distribution of geomorphic surface is the main geomorphologic characteristic of Guizhou and its adjacent areas,and the detailed study of this characteristic is very important in reconstructing Cenozoic evolution. Taking Guizhou and its adjacent areas as the study district, based on ASTER-GDEM data (30 m) and using ArcGIS platform,the authors extracted the geomorphic surfaces with slope data and statistical method,and obtained the precise quantitative features of the geomorphic surfaces in this district for the first time. The results provide a new insight into the study of step-like landforms. It is shown that there are 4 steps of geomorphic surfaces in the study district, which suggests that Guizhou and its adjacent areas has experienced at least 3 times of complicated tectonic uplift since Cenozoic with the uplifted elevation being 300~500 m each time, and remain in the process of uplifting at present.
