摘要
建立多种水生植物模拟控制实验,揭示洱海湖滨大型水生植物组合在湿地中去除氮磷功能的差异:纸莎草、再力花和芦苇与其他植物搭配组合对氮磷去除效果最佳;美人蕉对水质的影响效果最不稳定,但当美人蕉与其他植物搭配时,却起到很好的水质影响效果。挺水植物可以较快地降低水体氮磷水平,但是氮磷去除率与水体氮磷含量成正相关关系。
Removal effects of nitrogen and phosphorus on wetland plant assemblages were studied by the wetland plant experiments in Miju River, Erhai Lake. Papyrus, Hardy C a n n a, and Reed had the best removal effect of ni-trogen and phosphorus. Canna had a poor result. However a better effect was appeared when Canna assorted with other plants. Emergent plants could remove nitrogen and phosphorus rapidly. But their removal effects of nitrogen and phosphorus were positively correlated with the concentrations of nitrogen and phosphorus.
