| 摘 要： | 连续6年对星湖仙女湖区水生植被种类、分布、生物量、水体状况进行了调查研究；共采集到水生植物24种，隶属于18科23属，可分为挺水植被、漂浮植被、浮叶植被和沉水植被4种生活型和8个植物群丛，其中苦草群丛占水生植被生物量70％以上，密齿苦草为绝对优势种；2004年与1999年比较，星湖仙女湖水体叶绿素a增加142％，透明度下降54％，水生植被盖度和生物量减少99％，水生植被群落结构趋于简化、多样性下降；星湖仙女湖水生植被发生逆向演替的主要原因是水体污染负荷增加和渔业生产的影响，削减污染负荷和控制渔业生产是促进星湖仙女湖水生植被恢复的重要途径．

| 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. |
