    Throughy the study on the ecological effects of Cd and Zn onseveral aquatic plants,the ecological sensitivity of 5 species is determined.The results show that according to critical time when plants are injured by Cd and Zn,the order for ecological sensitivity of 5 species is:Nymphoides peltatum＞Hydrilla verticillata＞Potamogeton malaianus＞Spirodela polyrhiza＞Alternanthera philoxeroides.The results also show that on basis of catalase activity of aquatic plants,the order for ecological sensitivity of 5 species is:Alternanthera philoxeroides＞Spirodela polyrhiza≈Potamogeton malaianus＞Hydrilla verticillata＞Nymphoides peltatum.It is evident that the pollution-durablty Potamogeton malaianus is higher than for Nymphoides peltatum and Hydrilla verticillata,pollution-sensible species
