Abstract :
Non-point source pollution has became a major water pollution source in Northeast China. A small typical agricultural watershed was selected to test the validity of the annualized agricultural non-point source (AnnAGNPS) model in Northeast China. The best available data were assembled in the analysis. The model validity was tested by nitrogen and phosphorus concentration data. A good correlation was observed in predict nitrogen concentration while a not satisfactorily result was got in predict phosphorus concentration. The model´s performance released the model could be used in predicting nitrogen NSP load in Northeast China but not suitable for predicting phosphorus NSP load.
