摘　　要：湖泊富营养化是一个全球性的环境问题,磷是湖泊富营养化的最主要的限制性因子之一。综述了富营养化湖泊沉积物中磷的化学形态、释放规律及其影响因素,并讨论了水生植物对湖泊内源磷释放的影响机制。Lake eutrophication was a serious environmental problem in the world and phosphorus was regarded as one of the most important limiting factors in the lakes. In this paper, chemical forms, release rules and the affecting factors of the phosphorus in the sediments of the eutrophic lakes were discussed. Furthermore, the effect of macrophytes on internal phos- phorus loading was also discussed.

关 键 词：湖泊富营养化 沉积物 内源磷 释放 水生植物
