摘　　要：依据2009年4月、5月的实测数据以及聊城市环境监测站数据和文献数据,采用综合营养状态指数法对东昌湖的富营养化状态进行评价;并根据各因子在综合营养状态指数中所占比重和地表水水质标准,对各因子做了比较。结果表明:东昌湖综合营养状态指数四月份为47.0、五月份为53.1,即四月份为中营养、五月份为轻度富营养;整体上东边湖区比西边湖区富营养化程度高;各因子对东昌湖富营养化的贡献,总氮和叶绿素为主,高锰酸盐指数和透明度其次,总磷最后;东昌湖近十年一直处在富营养化状态,综合营养状态指数值在60上下波动。Based on data measured in April and May 2009 as well as data collected from Liaocheng Environmental Monitoring Centre,an assessment of eutrophication of Dongchang Lake were made by using method TLI.Factors included in method TLI through analysis of their proportion of TLI values with Environmental Quality Standard for Surface Water were compared.Results showed that the status of the Lake was mesotropher（TLI 47.0）in April and light eutrophic（TLI 53.1）in May,and the east parts were more severely polluted than the west.According to factors contribution of eutrophication in method TLI,Chla and TN were dominated,followed by CODMn,SD and TP.The Lake has a middle eutrophication state with TLI value of（60±10）.
