摘要 建设长三角生态绿色一体化发展示范区是实施长三角一体化发展战略的突破口。该区域河网密布,水质状态直接影响着周边百姓的生产生活。为了更好地保障示范区水环境安全,分析了主要河湖太浦河、淀山湖、元荡、汾湖的水质现状及变化趋势。研究结果表明:经过近年来的治理,水质总体稳定向好,但湖泊的总氮和总磷仍然偏高;建议紧抓示范区建设契机,加强跨省市合作和分工,继续加大水环境治理力度。 The construction of the demonstration area on ecologically friendly development in the Yangtze River Delta is the first move and breakthrough in the implementation of the integrated development of Yangtze River Delta.The area is densely covered by river networks,and its water quality directly affects the productions and lives of the surrounding people.In order to better guarantee the safety of the water environment in the demonstration area,this paper analyzes the water quality status and trends of its main river and lakes:the Taipu River,Dianshan Lake,Yuandang Lake,and Fenhu Lake.The results show that water quality is well improved by surrounding rehabilitation in recent years,however the total nitrogen and total phosphorus of the lakes are still relatively high.It is suggested to seize the opportunity of the construction of the demonstration area,strengthen trans-provincial cooperation and division of labor,and continue to increase the intensity of governance.
