| Abstract: | To enhance the unity and accuracy of automatic extraction of gully erosion in the northwest loess plateau area,according to the requirements of China＇s first general investigation of water and soil conservation,the automatic extraction method for valley lines and river basins was studied,finding a comparatively big difference between the head of valley line and its true place.Several key problems were solved,thus realizing the automatic extraction task of gully erosion in the northwest loess plateau area. |
| Keywords: | gully erosion DEM valley line river basin |
