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)
