%X The study on the N and P removal and N2O release of eutrophic water body under planted float Ipomoea aquatica and Oenanthe javanica showed that planted float had a good effect on the removal of N and P from eutrophic water body. The bioaccumulation of N and P by the plants accounted for 40.32% approximately 63.87% of the N and P removal, respectively, suggesting that plant uptake was the main removal process. Within the treating period, there was a rapid and sufficient nitrification but a slow and insufficient denitrification in the planted float system, and thereby, planted float system had a high NH4+-N removal rate and NO3(-)-N accumulation. The presence of planted float reduced the release flux of N2O, which was 17.14 microg N x m(-2) x h(-1) for Ipomoea aquatica, 37.38 microg N x m(-2) x h(-1) for Oenanthe javanica, and 85.08 microg N x m(-2) x h(-1) for the control.
