大纵湖水环境污染分析及防治对策研究

大纵湖是江苏省里下河地区的重要湖泊之一，该文介绍了大纵湖自然概况，分析了大纵湖污染现状，如对水环境状况，出、入湖河流水质状况，底泥污染状况以及污染源状况进行了分析，并剖析了大纵湖水环境和污染源特征。针对存在的氮磷超标导致湖体富营养化、生态退化以及入境客水污染等主要环境问题，提出了控制污染物排放总量、修复湖泊生态、治理客水和强化水质监控等措施，为有效地改善大纵湖水环境质量，遏制湖泊富营养化趋势提供科学支撑。

Analysis on Pollution Status and Countermeasures of Water Environment in Dazong Lake

Dazong Lake is one of the most important lakes in Lixiahe District of Jiangsu Province. In this paper, the natural situation of Dazong Lake was introduced and the current pollution situation of Dazong Lake was analyzed. The pollution problems include, water environment situation, water quality of the river, sediment pollution status, pollutant source status and so on. Some measures were put forward to resolve the environmental problems such as eutrophication, ecological degradation and inlet water pollution. The countermeasures are controlling the total discharge of pollutants, repairing the ecological system of Dazong Lake, improving the water quality of influent rivers and enforcing the monitoring of water quality. These measures may be effective to improve water quality and to control the eutrophication.
