In this paper,AnnAGNPS model,in which GIS being integrated,was used to quantitatively simulate pollutant loads of Heigou watershed in Danjiang reservoir during the whole periods of 2003.

In the new sites of afforestation with narrow terrace at Shanshuigou gully of Hegou watershed in Xixian,fixed sample spots were designed.
