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.
