摘  要:比较了上海市徐汇区4个小水体3-5月浮游藻类群落结构和叶绿素a含量与水质的关系.康健公园内一条内河和上海师范大学内两个池塘种植水生高等植物和养殖鱼类,藻类数量少,叶绿素a含量低,修正的卡森营养状态指数TSIM(chl)处中营养状态,水质较好.桂林公园内一个池塘未种植水生高等植物和养殖鱼类,藻类数量多,叶绿素a含量高,修正的卡森营养状态指数TSIM(chl)处重营养状态,水质较差;并且4月由裸藻门的绿色裸藻(E.viridis)引起水华,水质恶化,处异常富营养状态.In the present paper, relationship between community structure of floating algae, content of chlorophylls and water quality of four small water bodies in Xu jiahui District of Shanghai Municipality was compared from March to May. In the freshwater of Kangjian Park and two ponds of Shanghai Normal University, higher water plants and fishes were cultivated, the amount of algae and content of chlorophylla were low, modified Carlson nutrition status index was moderate, so water quality was better. In the pond of Cuilin Park without higher water plant and fishes, the amount of algae and content of chlorophylla were high, modified Carlson nutrition status index was eutrophic, so water quality was worse. In April, water quality was deteriorated and in exceptionally eutrophic nutrition status, water bloom was composed of E. viridis.
