摘要
根据连续多年的水质监测资料,分析了鄱阳湖水系水质及湖体水质变化趋势.结果表明鄱阳湖水系水质及湖体水质均呈下降趋势,枯水期水质比丰水期更差;水系主要污染物为NH3—N、TN和TP,湖体主要污染物为TP和NH3—N;湖体富营养化程度均为中营养,有逐步向富营养化的趋势发展.
According to the data of water quality monitoring in Poyang Lake,we analyzed the status of the water quality and its changing trend in the water system of Poyang Lake.The result indicates that the water quality in the water system and Poyang Lake itself is dropping,low water period being worse than high water period;the main pollutants are NH3—N,TN and TP in water system,TP and NH3—N in Poyang Lake and the water quality is of medium-eutrophication and will run to eutrophication step by step.
