| 摘 要： | 为了科学评价伊乐藻在水生态修复中的实际应用价值,在模拟条件下初步研究了沉水植物伊乐藻（Elodea nuttallii）对污染水体中氮、磷的净化效果及其克藻效应。结果表明,伊乐藻对总氮、氨态氮、硝态氮和总磷均具有一定的净化效果,并且水体中氮、磷起始浓度越高,其去除效果越明显;不同生物量伊乐藻对河水中其他藻类均具有较强抑制作用,并且随着生物量增加,其克藻效应更加明显。

| Abstract: | In order to evaluate the role of Elodea nuttallii in aquatic ecological restoration,the purification effect of N and P by Elodea nuttallii were studied,and allelopathic effects on other algae were also investigated by a series of lab experiments.The results showed that Elodea nuttallii could decrease the concentrations of TN,NH＋4-N,NO-3-N and TP significantly;The initial concentration of N and P was higher,and the purification effect was better,such as the water with tolerant concentration;The inhibition function on other algae by Elodea nuttallii with different biomass was very obvious in water;Moreover,the biomass was higher,and the allelopathic effect displayed more distinct. |
