| 系统分析了鄱阳湖2015年度枯水期主湖体、五河入口、湖口过江水道、赣江下游主河道和南昌市周边湿地表层水体中总氮、总磷、汞、铜、锌、铅、镉等几种污染物的含量，结果表明：①2015年度鄱阳湖枯水期水体中总氮、总磷和铜的平均浓度分别为3.145mg/L、0.121mg/L和0.089mg/L,总体偏高；汞、铅、锌、镉的平均浓度为5.932×10-4mg/L、0.408mg/L、0.0645mg/L和4.516×10-2mg/L。总氮、总磷和铜在空间分布上存在差异性，表现为饶河河口、吴城望湖亭和湖口等区域的污染情况较为严重，南矶山碟形湖的污染程度最轻。 |
| 英文摘要: |
| The present study measured the contents of water pollutants (i.e., total nitrogen, total phosphorus, mercury, copper, zinc, lead, cadmium) in the Poyang Lake, the estuaries of the five-river, river channel at Hukou, the main river downstream of Gan River and wetland around Nanchang during dry season of 2015. Results showed that the mean concentrations of total nitrogen, total phosphorus and copper in Poyang Lake were respectively of 3.145mg/L、0.121mg/Land 0.089mg/L; The mean concentrations of mercury, zinc, lead and cadmium were respectively of 5.932×10-4mg/L、0.408mg/L、0.0645mg/L and 4.516×10-2mg/L. There were significant differences in the spatial distributions of total nitrogen, total phosphorus and copper, which were much higher in the regions of the estuaries of Rao river, Wanghuting at Wucheng and Hukou while were relatively lower in disc lakes at Nanjishan. |
