| 摘 要： | 通过对2002年7月长寿湖发生严重富营养化时的监测，利用富营养化评价标准对产生富营养化的几项主要指标进行综合评价，评价结果表明；长寿湖水体已经处于富营养化状况，在所有监测点，总磷，总氮浓度高，其中总氮超标严重按GB3838-2002地表水环境质量标准评价，已经为劣V类水，长寿湖水体中主要的植物为稀脉浮萍和少量紫背浮萍，造成长寿湖水质污染的主要原因有3个方面；工业和生活废水污染，地表径流污染和养殖业污染。

| Abstract: | Analysing the main eutrophication factors by the eutrophication standard in July 2002.The research indicated that the water body was at the level of eutrophication in Changshou Reservoir.The content of totel nitrogen and totel phosphorus were high.Totel nitrogen was below of environmental quality standard for surface water fifth in all of monitoring sites.The main plants were Lemna Paucicostata and Spirodela polyrhiza. The three main factors affecting the water quality were aquatic breeding products pollution,nonpoint pollution,industrial waste water and domestic sewage pollution in Changshou Reservoir. |
