【摘要】 磷是湖泊富营养化的主要限制因子,在此综述了沉积物中磷的赋存形态,释放机理及其影响因素。内源磷的赋存形态主要分为铝磷、铁磷、钙磷及有机磷,磷释放受pH值、溶解氧、生物、温度、扰动等5种因素影响,对富营养水体内源磷释放的影响因素及其机理进行研究,可为富营养化水体的治理提供理论依据。更多还原

【Abstract】 The level of eutrophic lake is mainly dependent on the factor of phosphor. In this paper, chemical forms, release rules, and their affecting factors of phosphorus in the sediments of eutrophic lake were discussed. The chemical forms of internal phosphorus is divided into such forms as PAl?PFe?PCa and Porg. The release of phosphorus is affected in such a manner as pH?DO?organism?temperature and turbulence. Study on the affecting factors and its mechanism of internal phosphorus release in eutrophic water can provide theoretical basis to the treatment of eutrophic lakes.更多还原
