沉积物中磷形态及影响其释放的环境因素研究进展

Research progress in phosphorus forms in sediments and environmental factors that influence phosphorus releasing

磷是控制水体富营养化最关键的营养物质,在外源磷得到控制之后,内源磷通过各种复杂过程再次进入水体,成为水体富营养化的主要磷污染源。目前,国内外对底泥磷的相关研究已非常多,但缺乏系统的整理和总结。从底泥磷的形态和影响其释放的环境因素2个方面进行了系统总结,介绍了底泥磷的主要形态、释放机制,分析了环境因素对于底泥磷释放的影响。

Phosphorus is a key eutrophication factors of the majority of water bodies. After the outside phos- phorus pollution sources all under control,endogenous phosphorus enter into water bodies through series of complex process and become the main phosphorus pollution source of eutrophication. Nowadays, there are lots of studies on sediment phosphorus all over the world, but lack of comprehensive systemize and conclusion. In this paper, the endoge- nous phosphorus pollution was systematic summarized from following aspects., phosphorus forms in sediment, the mechanism of phosphorus releasing and the environmental factors that influence the phosphorus releasing. Some controversies and drawbacks of the existing researches were analyzed so as to provide some help to the subsequent investigation in this field.
