摘    要:近二十年的水质监测资料研究分析表明,抚仙湖生态系统相当脆弱,出现了加速富营养化趋势,浮游藻类数量增加了2.6倍,Chl.a含量增加了3倍,透明度减小了将近一半,综合营养状态指数呈急剧上升,揭示了发生富营养化的危险性。促进因素主要有外来污染增加,氮、磷等营养盐在湖内迅速积累,湖泊生态系统过于简单、脆弱等因素,呼吁加大对抚仙湖污染防治的力度,防患于未然。

关 键 词:抚仙湖  富营养化  探讨  水质监测  污染防治

Abstract:Fuxian Lake is a deep lake with a capacity of 184×108 m3. Based on the incessant monitoring statistics during 1980-2000, the water quality as well as the eutrophication status was revealed in Fuxian Lake,.i.e. the phytoplankton density increased 2.6 times, Chl.a 3 times while SD decreased~50%. Comprehensive assenssment of nutrient status and evolution during the past 20 years indicated that a sharp growth of TSI would bring out a potential possibility and danger of eutrophication which has compelled us to take some efficient, effective measures to protect the lake from further deterioration or invaluable lose both economically and ecologically in the future would be seen.
Keywords:Fuxian Lake  eutrophication
