对安庆市城区的六个湖泊水体的重金属、油类、总磷、总氮、氨氮、化学需氧量等污染指标进行了分析，分析可能的污染来源，构建模糊评价模型评价水质。结果表明：1）污染物空间分布呈现为市内中心处的湖泊含量高周边湖泊含量低的特征，且不同湖泊污染物类型不同，表明存在不同的污染来源；2）采样中发现存在暗渠排放进入水环境，表明该市偷排现象依然存在；3）城区湖泊均为Ⅲ类水体，基本符合其功能需要，主要污染物为有机污染物总氮和氨氮，但个别污染物污染比较严重，例如油类的含量在各个湖泊均在（0．18-0．2） mg/l之间，为Ⅳ类标准，西小湖的 TN含量大于2．0 mg/l，为劣Ⅴ类标准，高锰酸盐指数在东大湖、莲湖以及菱湖内均在（6-15）mg/l之间，属于Ⅳ和Ⅴ类标准。因此湖泊水质变化趋势需要进一步关注。

To monitor the surface water quality of urban lakes in Anqing city , the physical and chemical indicators such as heavy metal, oil, TP, TN, NH4+-N and CODMn from six urban lakes are analyzed.The source analysis of different contaminants and comprehensive evaluation of water quality from six lakes are also conducted .The results show that the high levels of most con-taminants are detected in lakes which locate in city center, then reduce in the lakes which locate in the edge of city.Some contam-inants are found from several culverts;those illicit emissions should pay close attention .The fuzzy comprehensive evaluation model reveals that the water quality of all urban lakes is grade Ⅲ, and that the TN, NH4+-N and CODMn are the predominant contami-nants in those lakes.However, the pollution of some compounds are very serious.For instance, the levels of oil are ranged from 0. 18 to 0.2 mg/l, which belonged to the Ⅳ.The TN levels in Xixiao Lake are higher than 2.0 mg/l, which belonged to Ⅴ.The levels of CODMn in Dongda Lake, Lian Lake and Ling Lake are ranged from 6 to15 mg/l, which belong from Ⅳ to Ⅴ.Further , the research should be done to track the trend of the water quality in Anqing urban lakes.
