Simulation and Validation of Non-Point Source Under Different Hydrological Years in Miyun Reservoir Watershed

摘要

Climate change is likely to impact terrestrial and aquatic ecosystems via numerous physical and biological mechanisms.Hence,we need a methodology that can predict the influence of different climate scenarios using the better assessment science integrating point and nonpoint sources (BASINS) hydrologic simulation program—FORTRAN (HSPF) model.The Miyun reservoir watershed was selected as the study area,as an important drinking water source of Beijing,the water quality of Miyun reservoir is crucial.Simulation of non-point source pollution (NPS) in Miyun reservoir watershed was performed by establishing the spatial database and the attribute database required by the model.
