摘要: 研究了3种沉水植物对不同质量浓度富营养化水体的净化能力,结果表明,轮叶黑藻、金鱼藻和狐尾藻对水体中的氮、磷都有很好的净化效果,对总氮去除能力从大到小依次为轮叶黑藻>金鱼藻>狐尾藻,对总磷去除能力从大到小依次为轮叶黑藻>狐尾藻>金鱼藻。实验表明,沉水植物是富营养化水体水生态系统重建的关键,在水体生态修复中,轮叶黑藻是一种很好的水体净化沉水植物。

Abstract: We studied the effects of three submersed macrophytes of Hydrilla verticillata, Ceratophyllum demersum L. and Myriophyllum verticillatum L. on eutrophication water under different nutrition conditions. Three submersed macrophytes eliminated total nitrogen(TN) and total phosphorus(TP) effectively in water. The eliminate capacity for TN from high to low was H.verticillata, C.demersum L. and M.verticillatum L., and for TP the order was H.verticillata, M.verticillatum L. and C.demersum L.. Therefore, the submersed macrophytes is a significant method to reconstruct the eutrophic water ecosystem, and H.verticillata is a good purifying plant in eutrophic water.

Key words: submersed macrophytes, eutrophication, total nitrogen(TN), total phosphorus(TP)
