从浮游植物的变化看光合细菌在治理富营养化水体中的作用

THE EFFECTS OF PHOTOSYNTHETIC BACTERIA ON CONTROLLING EUTROPHIC WATER THOUGH THE CHANGES OF PHYTOPLANKTON

以浮游植物的种类组成、细胞密度、优势种及叶绿素a的质量浓度的变化等几项参数 ,对光合细菌在治理北京动物园水禽湖严重富营养化水体中的作用进行了监测评价 .初步结果认为 ,光合细菌对于富营养化水体中浮游植物的数量和形成水华的铜绿微囊藻有一定的调控作用 .

Though the changes of phytoplankton on the species compose, the amount of cell and chlophyll a and the dominant species, the effects of photosynthetic bacteria on controlling the serious eutrophic water of Shuiqin Lake in Beijing Zoo were inspected and evaluated. The preliminary result shows that photosynthetic bacteria can regulate the amount of phytoplankton, especially the species Microcystis aeruginisa which can form water bloom, to some extent.
