| 摘 要： | 对东昌湖轮虫群落结构、种群分布和丰度进行了初步研究。在湖区共检出8种轮虫，隶属于5属，其中优势种群为萼花臂尾轮虫（Brachionus calyciflorus）、角突臂尾轮虫（Brachionus angularis）和壶状臂尾轮虫（Brachionus angularis），平均丰度为618ind．／L。轮虫的种群分布及生物多样性在东昌湖三个湖区因污染程度的不同而存在着较大的差别。

| Abstract: | The community structure and population distribution of rotifera in Dongchang Lake was studied . The results revealed that the community of rotiferan involved 5 genus and 8 species with total biomass of 618 ind./L, in which three species, Brachionus calyciflorus, B. angularis and B. urceus, are dominants in the three area of lake, respectively. In addition, it is demonstrated that the community structure, population distribution and diversity of rotiferan are considerable different in three area. |
