| 摘 要： | 对紫萍、大和凤眼莲3种水生漂浮植物处理富营养化水体的研究结果表明,3种漂浮植物对去除富营养化水体中的全N和全P、增加水体中的溶解氧有明显效果,且能有效抑制藻类生长,处理效果大>凤眼莲>紫萍。大和凤眼莲均具有较强的环境适应能力,但大生长繁殖较易控制,且对富营养化水体治理效果佳和改善水质,有综合利用价值。

| Abstract: | Three aquatic floating plants,Lemma polyrhiza L.,Pistia stratiotes,and Eichhornia crassipes,to treat the water eutophication were studied. The results indicate that these three plants can reduce the N and P,increase the dissovled oxygen,and restrain the growth of algae efficiently in eutrophication waters;however,the sequence of treating (efficiency) is Pistia stratiotes>Eichhornia crassipes>Lemma polyrhiza L.Pistia stratiotes and Eichhornia crassipes have strong abilities to suit the various environment,and the growth of Pistia stratiotes is easily to control.Therefore,Pistia stratiotes is recommended as a preferable aquatic floating plant to treat eutrophication waters. |
