摘要
介绍了湖泊沉积物中磷的存在形态和释放机理,并对影响沉积物中磷的释放的各种因素进行了分析。主要分析了温度,pH值,溶解氧,沉积物的组成,光照和水动力的影响,认为影响释放的主导因素因地而异;认为沉积物-间隙水-上覆水三界面的磷的释放应作为一个整体来研究。
In this paper we gave a short review of the phosphorus retention in lake sediments" the mechanisms and factors suggested to be vital to phosphorus release from lake sediments. The release of phosphorus from sediment is influenced by many factors. The effects of temperature, pH, DO, form of phosphorus in sediment and hydrodynamic conditions were discussed respectively. The major influencing factors vary in different surroundings. Sediment-interstitial water-water interactions and the release of phosphorus should be studied as a whole body.
