Abstract：Community structure and water quality were investigated at four different sample sites (S1:east regulatinglock in river channel entering lake ,S2:static water area in south bay ,S3:center of Muye lake , S4:hydraulic car area) from July 2011 to May 2013 in Muye lake of Xinxiang city .The results showed that 43 rotifer species were found ,belonging to 14 genera ,7 families .The dominant species were Polyarthra trigla ,Brachionus calycif lorus ,Brachionus angularis ,Brachionus urceus ,Brachionus caudatus ,Filinia longiseta ,Keratella valga and Brachionus budapestiensis .The monthly average abundance of rotifers ranged from 13 ind/L to 8 901 ind/L ,and seasonal abundance order was summer> spring > autumn > winter .The seasonal differences of abundance were significant . Spatial abundance order was S2> S3> S4> S1 .The water quality of Muye lake was evaluated through ecological methods and weighted comprehensive nutrition state index method according to the rotifers .There were 24 os-β-ms ,β-ms-os andβ-ms rotifer species ,which accounted for 55.8%of the total species ,biology indexes(Q) ranged from 1.5 to 2.5 ,TL Ic values were all above 50 . The water quality of Muye lake and inflow river was in eutrophic level on the whole .
