| 摘 要： | 沉积物中部分固定的磷可通过分解或溶解作用而释放磷酸盐到沉积物间隙水中;再生的磷可能释放到上覆水体中,或在沉积物中作为一种自生相而再沉淀,或被沉积物的其它组分所吸附。本文描述了磷在沉积物-水界面的迁移过程,并对影响磷循环的因子及其磷自沉积物释放的机制作一简要概述。

| Abstract: | Part of the boundary P within the sediments can be released to the sediment interstitial water by decomposing or dissolving. The regenerated phosphate may be released to the overlying water and reprecipitated within the sediment as an authigenic phase, or adsorbed by other constituents of the sediments. The P transferring process on the sediments-water interface was described. On such a basis, the influencing factors and P release mechanisms were summarized briefly in this paper. |
