Abstract: Six macrophyte species(Phragmites communis,Typha angustifolia,Acorus calamus,Nymphaea tetragona,Scirpus validus,and Pontederia cordata) were grown in eutrophic ponds in order to test their removal efficiency for nitrogen and phosphorus,respectively.Among the six plants,Scirpus validus and Acorus calamus showed the highest removal efficiency,especially for Scirpus validus,it was worth to be applied in water treatment for its good adaptability.Nymphaea tetragona grew rapidly,but its stems and leaves could pollute water body after they fall off.Typha angustifolia showed the least efficiency in algae inhibition.
