| 摘 要： | 为比较不同湿地植物对富营养化水体中N,P的去除效应。研究了水葫芦、菖蒲、空心菜、金鱼藻等4种湿地植物对NO3-N,NH4-N及P的吸收动力学特征。结果表明,不同湿地植物对水体中N,P的吸收存在显著的差异,4种植物对NH4-N的最大吸收速率(Vmax)大小为水葫芦＞空心菜＞菖蒲＞金鱼藻,对NO3-N的最大吸收速率表现为水葫芦＞空心菜＞金鱼藻＞菖蒲；对P的最大吸收速率表现为水葫芦＞空心菜＞菖蒲＞金鱼藻；4种湿地植物对水体中氮磷吸收的表观米氏常数(Km),即亲和力均呈现出与最大吸收速率相反的趋势。

| Abstract: | To compare the removal effects of N,P from eutrophication water by wetland plants.The uptake dynamics characteristics of NO3-N,NH4-N and P by four types of wetland(Water hyacinth,Acorus calamus,Ipomoea aquatica,Ceratophyllum demersum) were studied.The results showed that the four wetland plants showed significant difference in the water N,P uptake,and the maximum absorption rate of NH4-N showed as Water hyacinth> Ipomoea aquatica> Acorus calamus> Ceratophyllum demersum while the maximum absorption rate of N... |
