摘要
根据Koste（1978）提出的轮虫分类系统对鄱阳湖1987～1989年6个采样站的轮虫调查资料进行了分类，并报道了其现存量的调查结果。笔者共观察到轮虫85种，隶属子33个属，20个科。鄱阳湖轮虫新记录28种。鄱阳湖轮虫的数量变动曲线与生物量变动曲线都呈现夏、秋季两个高峰，冬、春季为低贬期。本文还简单地讨论了一些生态因子对轮虫的影响。
Seasonal changes of species composition and standing crop of Rotifera were investigated at six sampling stations in Poyang Lake during 1987～1989 with the improved Rotifera taxonomy (Kostes' taxonomy system of Rotifera). 85 Species of rotifera, belonging to 33 genera of 20 families, were reported. Of these, 28 species belonged new records for the Lake. There were two peaks, (i. e. stimmer peak, autumn peak), of the abundance and the biomass of rotifera in a year. The peaks of biomass were not exactly parallel to the peaks of abundances because there was different species composition of rotifera in different season. Some ecological factors influencing the seasonal fluctuation of rotifera were also discussed briefly.
