In this study, three species of water ornamental plants, Lythrum salicaria, Typha angustifolia and Iris wilsonii, were introduced to removing nitrogen and phosphorus in lightly polluted urban landscape water. The results showed the experimental plants were all growing well in lightly polluted water and the growth rates were: Lythrum salicaria 33%, Iris wilsonii 19% and Typha angustifolia16%, respectively. The removal efficiency of TN of Lythrum licaria, Typha angustifolia and Iris wilsoni were 55.42%, 62.65% and 57.59%, respectively. The removal rates of TP of three species of hydrophytes were Lythrum licaria 63.9%, Typha angustifolia 51.7% and Iris wilsoni 38.9%, respectively. Based on the removal efficiencies on nitrogen and phosphorus and landscape efficiency, the three species of water ornamental plants were recommended as pioneer in aquatic vegetation restoration in urban lightly polluted landscape river.
