升金湖国家自然保护区是我国重要的湿地自然保护区,通过实地调查,在分析升金湖植物群落现状与变化的基础上,探讨了水产养殖对升金湖植物群落的影响.调查发现升金湖共有水生和湿生维管植物43科94属125种,其中发现圆基愉悦蓼(Polygonum jucundum var. routundum Z. Z. Zhou et Q. Y. Sun)这一新亚种;滩涂植物群落主要为白朗苔+阿齐苔群丛(Ass. Carex brownii+Carex argyi )、圆基愉悦蓼群丛(Ass. Polygonum jucundum var. routundum)和蓼子草群丛(Ass. Polygonum cripolitanum);水生植物群落包括菰群丛(Ass. Zizania caduciflora)、菱群丛(Ass. Trpa sp.)、芡群丛(Ass. Euryale ferox)、菹草群丛(Ass. Potamogeton crispus)、金鱼藻群丛(Ass. Ceratophyllum demersum)、聚草+金鱼藻群丛(Ass. Myriophyllum spicatum+Ceratophyllum demersum)、聚草+苦草+水车前群丛(Ass. Myriophyllum spicatum+Vallisneria natans+Ottelia alismoides)等.目前全湖水生植被的盖度仅约30%.通过多年的调查记录对比,升金湖沉水植被严重退化,过度的水产养殖可能是主要因素,保护水生植被刻不容缓.
