沙颍河流域面源污染负荷空间分布特征研究
Research on spatial distribution of non-point source pollution load in Shaying River Basin
摘要
Abstract
The Shaying River is a heavily polluted river in the Huaihe River Basin. In order to correctly analyze the spatial dis-tribution of non-point source pollution load in the Shaying River Basin, according to the existing research results, by using the improved export coefficient model composed of five modules including rural life waste water, farmland fertilizer loss, loss of live-stock and poultry breeding, soil erosion and urban surface runoff pollution load, the spatial distribution of the non-point source pollution load in the basin was simulated and estimated. The results show that the load of four pollutants ( COD, TP, TN, ammo-nia nitrogen) in the upstream is the largest, followed by the midstream and the load per unit area in the midstream is the largest, which shows that the midstream of Shaying River will be the key for watershed pollution management.关键词
