Abstract

 In order to find practical strategy for controlling eutrophication in Lake Taihu, in this study, water quality and biota were investigated in East Lake Taihu, Meiliang Bay and West Lakeshore. Compared with the lower nutrients concentrations in East Lake Taihu, the values of Chl.a, turbidity, T-N and T-P showed significant fluctuations with eutrophication level in different places of Meiliang Bay and West Lakeshore. There was significant positive correlation among each value of Chl.a, T-N and T-P in Meiliang Bay, which indicated that the occurrence of water bloom was related to the concentration of nutrient. According to the result of identification, there were totally twelve species of aquatic macrophytes in the investigated area, of which two species were found in Meiliang Bay, one species was found in the southwest coastal zone, and twelve species were found in East Lake Taihu including six species as dominant submerged plants. There were ten species of Cyanophyta during the water bloom in East Lake Taihu and Meiliang Bay, of which <i>Microcystis aeruginosa</i> was found with large quantities of biomass as dominant species. Apart from the Cyannophyta, 21 species of diatom and 20 species of Chlorophyta were identified in East Lake Taihu and Meiliang Bay, of which 41 species were spread in East Lake Taihu. The relatively richer macrophytes community and phytoplankton indicated the higher biodiversity conditions in East Lake Taihu.
