南水北调进京水营养化态势及对策研究

Study on countermeasures and the nutrition of water in South-to-North water diversion project

南水北调调水进京后,作为北京市的主要水源,其水质安全关乎百姓安危、社会稳定和国际影响,是南水北调平安调水的生命线。利用第一手监测资料,对南水北调进京江水进行了水质、富营养化和浮游藻类时间和空间对比分析评价,找出了主要水质指标、重要营养因子和各个时期水体中浮游藻类优势种群的变化规律,分析了南水北调江水进京后面临的基本问题,进行了论证和评价,提出了建议和措施。

Water from South-to-North water diversion project is the main water source of Beijing, of which water quality safety is related to the safety, social stability and international influence. Obviously, its water quality safety is the lifeline of the ping＂ an water diversion. Based on the first-hand monitoring data,comparation and analysis of spatio-temporal variations of its water quality, eutrophication and phytoplankton are carried out to find out the main water quality index, important nutrients and the variation rule of phytoplankton dominant species in each period. This paper also analyzes some basic problems of the South- to-North water diversion project, and lastly puts forward some corresponding suggestions and measures.
