摘要
利用非生物因子、浮游植物密度、生物量、种类组成及初级生产力等生物学指标对官厅水库(北京段)3个水体的富营养化状况进行了评价与分析。结果表明:该水体已达到富营养化状态,主成分分析显示对水体富营养化影响较大的水化因子首先是氮,其次是磷。文中简要分析了氮、磷来源,并提出了治理措施。
The eutrophication status of Beijing part of Guanting reservoir in Beijing was evaluated based on abiotic environmental factors,and species composition,density,biomass and primary productivity of phytoplankton.The Beijing part of Guanting reservoir was found under eutrophication.The principal component analysis（PCA） showed that the nitrogen element（N） was the primary impact factor,following by phosphorus element（P）.Sources of N and P element and control methods of eutrophication were discussed.
