| 摘 要： | 综述了富营养化水体沉积物中磷的化学形态、释放规律及其影响因素。化学形态分为水溶性磷、铝磷、铁磷、钙磷、还原态可溶性磷、闭蓄磷、有机磷等 7种 ,其分布取决于各形态磷的性质。磷释放受 7种因素影响 ,厌氧、高 pH或低 pH值、高温、扰动、生物活动、底泥与水体含磷量的浓度差值以及钙质沉积物组分等因素均能促进沉积物中磷的释放。

| Abstract: | In this paper, chemical forms, release rules and their affecting factors of phosphorus in the sediments of eutrophic water were discussed. There are 7 forms including P sol ,P Al ,P Fe ,P Ca ,deoxidized soluble P,P o-p and P org . Anaerobic, higher pH or lower pH value, higher temperature, mixing, bioturbation, higher P concentration gradient and calcareous sediments composition conditions would improve the release of phosphorus. |
