摘要
本文报道了北京通惠河原生动物群落多样性特征与永质的相互关系。其中ＰＦＵ原生动物１天的群集速度（功能参数）较好地反映了５个采样站（１个设在较干净水体温榆河作为对照站）水质的变化趋势。各站原生动物群落的结构参数（种类组成、个体丰度、生物量和多样性指数）的差异同样与水质关系密切。通过与８０年代中期作者利用ＰＦＵ原生动物监测通惠河污染现状和自净效能的研究资料进行比较，表明该河流水质目前得到明显的改善。
This paper deals with the relationship between community diversity of protozoa and water quality in Tonghui River.The PFU protozoan colonization rates during a day reflects water quality's changes in five sampling sites——four in Tonghui River,one in Wenyu River as a control site.Protozoan community parameters(species composition,individual abundance,biomass and diversity index)in five sites is strongly related to pollution situation.Present research on PFU protozoan monitoring shows that water quality in Tonghui River has greatly been improved in comparison with 1980's data for PFU protozoan community's assessment conducted by author.
