中文摘要：

植物修复富营养化水体具有成本低、效果好、简单易行、且可改善生态环境等优点,具有广阔的应用前景。高等水生植物在生长过程中能够大量吸收水体中的N,P等营养物质,同时释放化学物质,抑制浮游藻类生长,从而达到净化水体的效果。在此主要从分子水平介绍了植物去除富营养化水体中N,P的作用机理。

英文摘要：

Phytoremediation is a promising new technology which has the advantages including low costs,good efficiency,easy operation and eco-environment improvement.Advanced aquatic plant can assimilate much N and P from water and release chemical materials at the same time to restrain algae growth and purify eutrophic water.The mechanisms of phytoremediation for N and P in eutrophic water were introduced based on the molecular level.
