摘要

Abstract

The spatial heterogeneity of the standing crop of protozoa in Lake Donghu was observed during 1993-08-1994-08.The annual mean abundance of protozoa was 59.391 ind./L,and the biomass was 1.40 mg/L.With the increase of the trophic levels(TSI),there was an obvious increase both in abundance(A) and biomass(B)of protozoa.The succession of the annual dynamic model of protozoan abundance was found,the higher the trophic level,the higher peak in winter.The horizontal spatial pattern of protozoan community structure had a same trend with long-term changes caused by trophic levels in Donghu Lake.
