SWAT model of non-point source pollution under different land use scenarios in the Heihe river basin
|
Abstract:
GIS data was combined with environment model SWAT2000 and landscape ecology in order to determine the relationship between land uses and non-point source pollution(NPS) in the Heihe River basin. Considering land use deterioration and improvement, the discharge,sediment and nutrient load parameters of the model were verified and calibrated. The model was tested by applying it in the Heihe river basin. Through quantitative analysis of the non-point source pollution (NPS) load of different land use scenarios, ...
