摘  要:
Producing DEM from vector contour map as well as using the principles of runoff model to extract ditch line were introduced in this paper.With the aid of GIS software and taking region of Dabie Mountain in Anhui Province as the example,the DEM was established and the gullies were extracted as well.At last,the deficiency of the findings was pointed out too.
