摘要
随着经济的发展 ,长江三角洲地区的富营养化 ,如蓝藻、水葫芦爆发等问题日趋严重 ,给该区的可持续发展带来了严重的后果。本文结合太湖、淀山湖、阳澄湖的多年环境监测资料 ,探讨了长江三角洲湖泊富营养化的现状和发展趋势 :湖泊氮磷和耗氧性有机污染物含量逐年上升 ,每十年水质下降一个级别 ;局部水域富营养化严重 ,近 15年上升了一个营养级别 ;富营养化持续加重加剧。继而分析了形成湖泊富营养化的主要污染物源 。
With the development of economy in the Yangtze River Delta district,eutrophication which brings about the bloom of green alga,hyacinth and so on,has become more and more serious.Combined with environmental monitoring information of Taihu Lake,Dianshan Lake and Yangcheng Lake,the status quo and trends of lake eutrophication in the Yangtze River Delta have been studied.It was founded that TN?TP and COD Mn have a great increase gradually and heavy eutrophication presented to some water area.Based on the analysis of lake eutrophication patterns and origins,control countermeasures have been presented.
