摘要： 种植业的面源污染，按流域尺度的研究可以宏观反映某一地区的面源污染现状。因此，本研究基于江西省的农业面源污染普查数据，比较了不同流域内种植业的氮磷化肥用量和面源污染情况。结果表明：江西省各流域种植业中化肥量呈现出赣江流域>抚河流域和鄱阳湖流域>信江流域>外河流域>饶河流域和修河流域，其中以赣江流域最高，其氮肥和磷肥占全省的比例分别为51.7%和51.2%。面源污染物的排放量也呈现出赣江流域较高，其COD、TP、TN、NH3-N分别占全省排放总量的62.3%、56.3%、53.4%和53.4%。COD、TP、TN、NH3-N的排放强度也分别比全省增加了47.5%、26.5%、21.8%和14.8%。因此，赣江流域是江西省种植业的面源污染防治和化肥减施行动的关键的治理流域。

Abstract: In planting industry, non-point source pollution situation of one region can be shown macroscopically through the scale research of river basin. Therefore, the census data about agricultural non-point source pollution (ANSP) in Jiangxi was used in this study, then, nitrogen (N) and phosphorus (P) fertilizer rate and ANSP were compared among different river basin. The results showed that: there was different in N and P fertilizers among all river basins in Jiangxi, they were shown: Ganjiang river>Fuhe river and Poyang lake>Xinjiang river>outside river >Raohe and Xiuhe river; meanwhile, the fertilizers amounts in Ganjiang river was the highest, the ratio of the N and P fertilizers with total province were 51.7% and 51.2%; ANSP also showed that Ganjiang river basin was highest, the ratio of COD, TP, TN and NH3-N emissions with total province were 62.3%, 56.3%, 53.4% and 53.4%, respectively, then, its COD, TP, TN and NH3-N emissions intensity were increased by 47.5%, 26.5%, 21.8% and 14.8% than that of province. So, the Ganjiang river basin was key region in Jiangxi for ANSP control and chemical fertilizer reduction.
