| Abstract: | From March to June in 1988, the authors made a preliminary study on the freshwater protozoans of Yongdeng Country.The study is related to classification, the relationship between the distribution of the species and the mein ecological factors fo the environment. 58 species of protozoa altogether have been disco- vered in the study. From the study, we have found out that the species, the amount and the distribution of the protozoa have close relations to the factors of the environment. If the other factors ars relatively. stable, the food is the restrictive factor. |
