Abstract
The species ,distribution and biomass of aquatic vegetation and water quality in Lake Xiannv of Lake Xinghu were inves- tigated and monitored for consecutive six years.The results show that aquatic flora in the lake covers 24 species which belong to 18 families,23 genus.,which could be divided into 4 community and 8 associations:emergent macrophyte community,floating macro- phyte community,floating-leaved macrophyte community and submersed macrophyte community.The community structure was sim- ple and the dominant of community was Vallisneria denseserrulate association which accounts for 70% more of the biomass of vegeta- tion.The water transparency decreased by 54% and the biomass and coverage of aquatic vegetation dwindled by 99% ,Chla concen- tration increased by 142% compared with 1999.The increase of pollution loading and fisheries is the principle reason for the varia- tion pattern of aquatic vegetation.Reducing pollution loading and controlling fisheries is the approach to the restoration of aquatic vegetation.
