摘 要：
研究了引污补水作用下小型通江湖泊——尚湖的浮游植物群落和营养盐时空变化。结果表明,尚湖共检出浮游植物8门、39属,从望虞河引水后,尚湖浮游植物群落组成中,蓝藻门富营养化习见种的种类显著增加;引水后尚湖的西湖区营养盐浓度上升2～3倍,东湖区基本维持不变;经过较长时间的沉降和水体自净之后,浮游植物群落中蓝藻门富营养化习见种的种类减少,营养状态降至引水前水平。从望虞河引水补给尚湖,对其浮游植物群落和营养水平有显著影响。

摘 要：
A research on phytoplankton structure change and spatio-temporal distribution of concentration of nutrients by pollution discharge and water intake in Shanghu Lake,a small Yangtze-connected lake,was conducted during October 2008 to September 2009.The results showed that:phytoplankton of 39 genera in 8 phyla was identified in the lake,but after water intake,common species of eutrophic blue-green algae increased significantly;the nutrients concentration in the western section of Shanghu Lake increased 2 or 3 times while that in the eastern section remained unchanged;common species of eutrophic blue-green algae decreased after long sedimentation and self-purification of water body,and trophic level descended to that prior to the water intake.The phytoplankton structure and trophic status in Shanghu Lake could be significantly affected by the water intake from the Wangyuhe River.
