This paper deals with the relationship between the protozoan community diversity and the water quality in the Baiyangdian Lake,the largest fresh water Lake in the Northern China Plain.Through two times of investigation, 77 species of protozoa were identified and 43 protozoan species were first recorded in the Baiyangdian Lake.PFU protozoan method was used to monitor water quality in two lake zones.Results of PFU protozoan colonization rates(one day),quantitative analyses and other parameters identically indicated that water pollution in the lake zone Ⅰ was much more serious than that in the lake zoneⅡ.Data of protozoa in 1990s were compared with those in 1950s to show the developing tendency towards eutrophication in this lake.
