中文摘要：

日益严重的水体富营养化现象，不仅降低了它的使用功能，也使水生态系统日趋退化，从而制约了当地社会经济的可持续发展。利用组建或重建沉水植物技术净化水质或进行水体生态修复是一种有效的生态工程措施。本文综述了光照、pH、营养盐、重金属、悬浮颗粒物及着生藻类等生态因子对沉水植物修复的影响和修复时应注意的问题。

英文摘要：

Increasingly worsening eutrophication not only has made the function of water body reduced, also has made the water ecosystem degenerated, which consequently restricted the sustainable development of local society and economy. By application of the technology concerning organizing or reconstructing the submerged plants to decontaminate or recover water quality is an effective measure of ecological engineering. This paper reviewed the ecological factors such as light, nutrient salt, heavy metal, suspended particulate matter and periphytic algae on the rehabilitation of submerged plants. Also some problems during the phytoremediation work were discussed.
