摘　　要：水体富营养化是当今世界面临的一个严峻的环境问题,很多研究表明:水体沉积物中磷的释放是引起富营养化的主要因素,因此国内外很多学者对水体沉积物中磷形态,磷释放的影响因素和控制技术进行了研究。研究发现:pH、温度、溶解氧、氧化还原电位和扰动等环境因子对沉积物中磷的释放均有影响,但其影响程度不同。国外关于水体沉积物中磷的控制技术的研究比较多,其中包括供氧技术、原位控制技术和覆盖技术等,还有近几年发现的水生植物控制技术,但国内对沉积物污染控制技术的研究还停留在实验探索阶段,应用的很少。Eutrophication has become a serious environmental problem in the world currendy. Many studies have indicated that the release of phosphorus from aquatic sediments was the main factor for eutrophication. So many researchers studied the forms of phosphorus in sediment, the impact factors of the phosphorus release and the control technology. The results showed that pH, temperature, dissolved oxygen, redox potential, disturbance and other environmental factors had effects on phosphorus release. There are more studies on control technologies for the phosphorus in the aquatic sediments on abroad, including supplying oxygen technology, in -situ control technology, capping technology and aquatic plants control technology found in recent years, but the study in China still remains in the experimental exploration stage and have less applications.
