摘　　要：研究了伊乐藻、菹草、微齿眼子菜、竹叶眼子菜、石菖蒲和水芹菜等水生植物在不同营养状态下体内富集N、P的能力。结果表明:植物体内氮磷浓度增加的趋势与所在水体中的氮磷去除效果相一致;挺水植物水芹菜和沉水植物微齿眼子菜吸收N、P的能力较强,可将这两种植物构成双层次群落结构用以修复太湖地区的富营养化水体。Several hydrophytes, in terms of Elodea canadensis Michx, Potamogeten crispus Linn, Potamogeton maackianus A. Benn, Potamogeton malaianus Miq, Acorus tatarinowii Schott and Oenanthe javanica（Bl. ）DC were used to investigated the ability of enrichment of nitrogen and phosphor at the different nutrition levels. The results showed that the rules of increasing of the N and P in the hydrophytes were coincident with the rules of pre- water-experiment, and confirmed Oenanthe javanica（BL ）DC and Potamogeton maackianus A. Benn are better hydrophytes to adsorb N and P, which can construct Floating Aquatic Macrophyte-based Treatment System（FAMS） for eutrophication water＇s remediation at Taihu areas.
