中文摘要 | A non-point source (NPS) pollution modeling system, the soil water and assessment tools for the Miyun Reservoir watershed, was used to identify temporal and spatial variations of NPS pollution in the watershed and to evaluate three pollution control scenarios. Soil and nutrient losses predominantly occurs during the flooding season, with nutrient losses during the flooding season reduced in dry hydrological years. Developed areas of agricultural and livestock production are key areas for NPS loadings, while areas covered by forests and grassland contributing less to the NPS loadings. Cutting livestock discharges and reducing fertilizer applications can efficiently reduce total nitrogen and total phosphorous loadings in the Chao River sub-watershed and can partially reduce total phosphorous loadings in the Bai River sub-watershed, but will have little effect in the total nitrogen loadings. Cutting domestic point sources in the towns of Dage and Chicheng will reduce total phosphorous loadings, but will have less effect on total nitrogen loadings. |
