Chinese Loess Plateau is considered as one of the serious soil erosion regions in the world. Nutrient loss through runoff and sediment in highly erodible areas not only decreases soil fertility, but also creates many environmental problems. In this study, an integrated modelling framework for the distributed coupling of hydrological process, soil erosion and adsorbed nonpoint source (NPS) pollution was established to investigate adsorbed NPS pollution in a typical watershed of Loess Plateau. Results indicate that: 1) the modified method is well validated and can be applied to the hilly and gully region, Loess Plateau; 2) the adsorbed total phosphorus (TP) load showed an overall decreasing trend from 1995 to 2012, the average TP pollution load from 2009 to 2012 reduced about 78% comparing with the early governance period (1995-1998), the high risk regions of TP load mainly occurred in the gentle sloping farmland which are located at the main river banks of the watershed. Results may provide data supporting for soil and water conservation planning in the hilly and gully region of Loess Plateau.
