A comprehensive survey on the quantitative distribution, community structure, species composition, dominant species, and species diversity of rotifer was conducted in the Mingzhu Lake of Chongming Island, Shanghai in January-December, 2008. There were 27 species of rotifer in the Lake, belonging to 8 families and 11 genera. The dominant species were Polyarthra trigla, Trichocerca pusilla, Brachionus calyciflorus, Brachionus forficula, and Philodina sp. The rotifer had an average annual density of (1505.42 +/- 1304.63) ind x L(-1), and an average annual biomass of (2.012 +/- 2.146) mg x L(-1). The Shannon-Wiener diversity index, evenness index, and richness index of rotifer community in the Lake were relatively low, while the dominance index was rather high, indicating that the community structure of the rotifer was unstable. The E/O value wes 1.61 +/- 1.46 on average, and the Q(B/T) values wes 1.23 +/- 0.84 on average. Water temperature was the main factor affecting the rotifer distribution. Biological assessment of water quality suggested that the Mingzhu Lake was on eutrophication.
2008年1月至12月，对上海崇明岛明珠湖轮虫的数量分布、群落结构、种类组成、优势种及物种多样性进行了全面调查。该湖共有轮虫27种，隶属于8科11属。优势种为长三肢轮虫、小型异尾轮虫、萼花臂尾轮虫、剪形臂尾轮虫和旋轮虫属。轮虫年平均密度为(1505.42±1304.63)ind x L(-1)，年平均生物量为(2.012±2.146)mg x L(-1)。该湖轮虫群落的香农-威纳多样性指数、均匀度指数和丰富度指数较低，优势度指数较高，表明轮虫群落结构不稳定。E/O值平均为1.61±1.46，Q(B/T)值平均为1.23±0.84。水温是影响轮虫分布的主要因素。水质生物学评价表明明珠湖处于富营养化状态。
