摘　　要：2014年3-5月,利用PFU法对汉中市兴元湖水中纤毛虫群落进行调查,从3个采样点共观察到56种纤毛虫,隶属1门,3纲,11目,32属。优势种为纵长板壳虫（Coleps elonqatus）、钝漫游虫（Litonotus obtusus）、钩刺斜管虫（Chilodonella uncinata）、珍珠映毛虫（Cinetochilum margaritaceum）、沟钟虫（Vorti-cella convallaria）、尾瘦尾虫（Uroleptus candatus）、伪尖毛虫（Oxyticha fallax）、阔口游仆虫（Euplotes eurys-tomus）。通过计算水体纤毛虫的多样性指数,大小关系为3号采样点﹤1号采样点﹤2号采样点。水质评价结果,1号采样点属于β-中污型,2号采样点属于寡污型,3号采样点属于a-中污型。The investigation on ciliates community and water quality assessment in Xingyuan Lake was carried out from April to May in 2014. Fifty-six species belonging to three classes of eleven orders of thirty genuses are discovered from three test sites. The dominant spices were Coleps elonqatus, Litonotus obtusus, Chilodonella uncinata, Cinetochilum margaritaceum, Vorticella convallaria, Uroleptus candatus, Oxyticha fallax and Euplotes eurystomus. Using species diversity index to assess water quality of Xingyuan Lake, the results showed that site one belonged to β-mesosaprobic zone; site two belonged to oligosaprobic zone; and site three belonged to a-mesosaprobic zone.
