浅水河湖沉水植物的恢复技术研究

目前,我国水域生态环境问题越来越严峻,浅水湖泊的富营养化导致浮游植物增加,沉水植物消亡,在外源污染物降低后,沉水植物的恢复仍然滞后相当长的时间,而沉水植物恢复技术研究在理论和应用上均有重要意义。从沉水植物在水体生态系统中的功能、净化富营养化水体的现状、恢复条件及恢复技术等方面论述了国内外浅水河湖沉水植物的恢复技术的研究概况,并对沉水植物恢复技术以及开发和利用沉水植物资源的前景进行展望。

Research on Recover Technology of Submerged Plant in Shallow Lake

At present,the problem of water ecological environment changes more and more serious,entrophication of shallow lake lead to the phytoplankton increasing and the submerged plants extinct.After reducing exogenous pollutants,the submerged plant recovery still lags for a long time.Research on theoretics and applications of recover technology of submerged plant are important.The function of submerged plant in water ecological system,the purifying entrophication status,the restore conditions and the recover technology of submerged plant were summarized.The prospect of recover technology of submerged plant research and the exploitation and utilization of water resources was presented in this paper.
