沉积物中磷的吸附和释放研究进展

Study progress of phosphorus absorption and release at sediments

为了研究内源磷的形态变化对水体富营养化的影响,对国内外的内源磷形态与吸附释放的研究进展作了简要的概述,研究结果表明:对于沉积物中磷的吸附和释放的研究多停留在单一因子的影响,而对两种或两种以上的综合作用的研究不多。而自然环境条件下,都是多因子的共同作用。因此,应对多因子对沉积物中磷吸附释放的影响进行线性和非线性的拟合,以便提出更有效的抑制沉积物磷释放的措施。

In order to study the influence of morphological changes of the endogenous phosphorus on eutrophicates of water, we gave a brief overview of the research on the shape of endogenous phosphorus release and adsorption in the world. The results of the research show that most of the researches of the adsorption and release of phosphorus in the sediment focus on single factor＇s effect. So there are few researches that focus on two or two more factors＇ integrated affection. In the natural conditions the multi-factor interacts most of time. We should have more linear and non-linear research on the multi-factor effect on the release and adsorption of phosphorus in sediment, so that we can propose a more effective way to inhibite the release of phosphorus in sediment.
