摘　　要：应用PFU微型生物群落监测方法,对长期处于低水位状态下的白洋淀水质进行了综合评价。结果表明,白洋淀水域受府河污水的影响,淀内的内源性污染,对原生动物群落造成了极大的影响。与20世纪90年代的资料相比,淀内中心区4个采样点原生动物的群集种类数(1d)急剧下降,而丰度上升了1.28倍,表明内源性污染对白洋淀水质的影响加剧。The water level of Baiyangdian Lake has been under lowstand state for 5 years.The current water quality of the lake was evaluated using protozoan communities,which were collected by PFU (Polyurethane Foam Unite) artificial subtracts.The results showed that Baiyangdian Lake was still affected by waste water of Fuhe River.The internal source pollution of Baiyangdian Lake had a strong impact on the protozoan communities.The colonization species of protozoa decreased,with the abundance increased by 1.28 times at four sampling plots.Compared with the data of the middle 1990s,the effect of internal pollution sources on Baiyangdian Lake was more serious.
