摘要/Abstract

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 Pconcentration gradient and calcareous sediments composition conditions would improve the release of phosphorus.

Key words: Crop simulation model, Application in regional scale, Remote sensing technique
