洪泽湖水质时空变化和富营养化研究

Study on temporal and spatial variation of water quality and eutrophication in Hongze Lake

为揭示洪泽湖水质时空变化和富营养化状况,研究基于2018—2020年洪泽湖区及入湖河流的水质监测资料,利用内梅罗指数和综合营养状态指数分别评价湖泊的水质状况和不同来水情况下的营养状态,并探究其影响原因,为相关部门制定洪泽湖水质改善措施提供依据。

In order to reveal the temporal and spatial variation of water quality and eutrophication status of Hongze Lake,Nemerow index and comprehensive nutritional status index were used to evaluate the water quality status of the lake and the nutritional status under different inflow conditions based on the water quality monitoring data of Hongze Lake area and inflow rivers from 2018 to 2020.Causes were explored so as to provide basis for relevant departments to formulate water quality improvement measures of Hongze Lake.
