长潭水库富营养化现状及防治对策

介绍了长潭水库的水文、功能及社会环境概况。跟踪统计分析了3个点位9年以来的监测数据和环境质量,研究显示,总体水质先降后升,水文因素非常明显。目前富营养化程度为中营养,主要污染因子波动指标为TP、TN、叶绿素a、pH值几个项目。同时分析了污染因子波动的原因以及氮、磷的来源。根据当地环境、经济状况,提出了控制水体富营养化的建议、方法。

Eutrophication Situation in Changtan Reservoir and the Protection Measures

The hydrology, function and social environmental of Changtan Reservoir were introduced. The water quality declined during the last nine years according to the analysis of environmental monitoring data and water quality from three position, one of the main reasons of which is hydrology condition. The eutrophication level is middle, as the main pollution factor were TP, TN, chlorophyll a and pH. The reasons of the fluctuation of pollutants and the source of nitrogen and phosphor were also analyzed. Suggestions and methods were given to control water eutrophication according to the local environment and economic status.
