摘要

Abstract

For compilation and comparison of desmids flora

the authors restudied the species composition

cell density and biomass of phytoplankton desmids collected at six stations in Donghu Lake at intervals of three months monitored from March of 1956 to February of 1957. A total of 122 taxa belonging to 16 genera were identified from qualitative and quantitative samples. Species ofCosmarium were the most popular ones occupying about 41% of the total species. Based on the observations

the annual mean values of the cell density and biomass were 132.11×102 cells/L and 0.09 mg/L.Cosmarium

Staurastrum

Staurodesmus andClosterium dominated and contributed more than 70% of the total cell density and biomass at six stations in four seasons. The maximum species number

cell density and biomass in autumn revealed that the highest variety (64 taxa

1296×102 cells/L and 0.889 mg/L respectively) occurred at Station 3 located in the southern part of Donghu Lake. From then on to the mid 1990s the desmids community decreased sharply in Donghu Lake

resulted clearly from eutrophication in the lake.
