Abstract: 51 species of protozoa are collected from soils under this forest.Monas guttula and other 9 species are wildly distributed.Flagellates is predominant in mean quantity,but Testacea is predo-minant in species numbers.There are marked differences in composition and quantity at different habitats,most in“gullyand grass site in the forest”,next in“Betula platyphylla forest”,and least in“broad-leave-koreanpine forest”.Protozoa generally concentrates in A00 and A0 layers,but seldom below 20cm.
