摘　　要：以NaN3 处理作为阳性对照 ,以自来水处理作为阴性对照 ,用紫露草微核监测法对抚仙湖具有代表性的 10个水样进行了监测评价 .结果表明 :各水样微核率与阴性对照相比都有较明显升高 ,邻近湖滨区域的水体污染程度远高于湖泊中心水体 ,湖泊南部的水体污染程度高于北边的水体 .这种变化与化学监测的结果是一致的 .Located in the middle of Yunnan Plateau,as the second deepest lake in China,Fuxian Lake is being polluted.Tradescantia micronucleus frequency were determinated in 10 water samples obtained from different sites of Fuxian Lake,and the mutagensis of the water samples of the lake were estimated.The results showed that the water along the shores of the lake was much more polluted than that in the central area of the lake,and the water in the southern part of the lake was more contaminated than that in the northern part of the lake.
