  • 摘要:This paper explores that photogrammetry first combined with GIS in our country to dynamically monitor and analyze the whole geomophological evolutionary processes assumed that this man made geomophological model was in the control of accurately controlled artificial precipitation. There were 9 low-altitude, close range vertical photogrammetric surveys conducted in different evolutionary processes in this area by using SMK-120 stereoscopic camera; and digital photogrammetric workstation (JX4) to carry out stereoscopic measurements and to gain high accuracy, high resolution DEM data, contour and profile data, ect. concerning different geomophological stages. All the geomophological shape parameters can be calculated in different geomophological stages in this area by using specifically designed software and DEM and many other data; to visualize and spatially analyze the space shapes in its geomophological evolutionary processes by using GIS and to provide scientific basis for geomophological studies and for soil erosion modeling. The studies show that photogrammetry and GIS are very important and valuable in geomophological studies and have prosperous applications in the future
