Abstract:By artificially imitatiing natual conditions, three aquatic macrophytes, namely Myriophyllum verticillatum L., Oenanthe javanica and Lolium perenne, were used to investigate their ability to purify the inflow river of Dianchi Lake. The efficiency of the system of enrichment and removal of nutrients in eutrophic water by aquatic macrophytes were discussed from the variation of the content of N and P in a three-phase structure of water-biology-sediment. All the hydrophytes absorbed the nutrients effectively. Myriophyllum verticillatum L. had a better enrichment ratio in the biology phase and Oenanthe javanica performed better to transfer the nutrients to the sediment phase. Aquatic macrophytes played a key role in purification by adsorption, sedimentation, metabolism and enrichment.
