Open publisher page 0 citations

Abstract

Taking Hunhe Basin for an example,SWAT model is used to simulate the non-point source pollution load.And then the yearly and monthly variation tendency is analyzed and the load distribution in 4 major districts is estimated.The result shows that the SWAT model has good applicability;non-point source is the main pollution load;annual average load has obvious variation with the precipitation changing;spring and summer are effective seasons for control of pollution.
