| 摘 要： | 应用浮游植物群落结构变化及富营养化指数来评价南太湖底泥疏浚工程对减轻太湖营养盐内负荷、控制湖泊富营养化的效果。研究结果表明：疏浚后水体中的浮游植物种类有所增加，浮游植物密度、生物量及蓝藻所占比例均有不同程度的降低，浮游植物群落结构发生变化；疏浚后水体的生物多样性指数发生变化，Shannon-Weaver指数升高，卡尔森营养状态指数降低，表明南太湖富营养化现状有所改善，从而揭示底泥疏浚工程对于减轻南太湖营养盐内负荷、控制湖泊富营养化具有积极作用。

| Abstract: | The ecological effect of dredging bed mud of southern area of the Tai Lake was assessed using phytoplankton community and trophic index.The result was indicated that the kind of phytoplankton was increased,while the density,biomass and the rate of Cyanobacteria were decreased obviously after dredge.The change of Shannon-Weaver index and TSIM index was indicated the dredging bed mud was helpful to trophic status of southern area of the Tai Lake. |
