【摘要】 为了鉴定武汉市汤逊湖桥梁建成后汤逊湖水体水质状况,2010年12月至2011年3月于汤逊湖沿线11个点多次采水样,以水体总氮、总磷、叶绿素a、COD及透明度等为参数,对水体理化因子、水质状态特征、富营养化程度等进行分析,探讨各影响因子对汤逊湖富营养化的影响程度.结果表明,汤逊湖目前处于轻度富营养化状态,工业废水、生活污水及水产养殖是汤逊湖的主要污染源.可通过加强对湖区工业污染源、城市生活污水、农业生产等污染的外源控制以及对湖区内的水产养殖污染的内源控制和科学管理,加强湖泊生态修复工程治理力度等方式进行调控.提出了汤逊湖水质富营养化治理的基本对策.更多还原

【Abstract】 In order to identify the water eutrophication conditions and characteristics of Tangxun Lake,we took water samples at 11 sites around Tangxun Lake from December,2010 to March,2011.With water total nitrogen,phosphorus,chlorophyll-a,COD and transparency as the parameters,we have analyzed and evaluated chemical factors of water,water quality characteristics,eutrophication level and other aspects of the research,and discussed the influence of different factors on the eutrophication of Tangxun Lake.We put forward basic measures to control the eutrophication of Tangxun Lake.The result shows that Tangxun Lake is at a mild rich nutrition.Industrial wastewater,sewage and aquaculture,etc,are the main pollution sources of Tangxun Lake.Measures are to strengthen the control of industrial pollution,urban sewage and agricultural production,to strengthen the aquaculture with control and scientific management,and to strengthen the ecological restoration project of the lake.更多还原
