摘要
本文讨论了湖泊沉积物中磷的各种存在形态，包括：可交换性溶解磷（Ｐ＿（ｓ－ｅ））．可溶性磷（Ｐｓｏｌ）￣［１］，铝结合态磷（Ｐ＿（Ａｌ））。铁结合态磷（Ｐ＿（Ｆｅ）），钙结合态磷（Ｐ＿（ｃａ））．以及闭态磷（Ｏ－Ｐ）．另外．还有部份有机磷（Ｐｏｒｇ）。利用分级提取技术，将各种不同形态的磷分别提出，并且定量检测。同时在厌氧与好氧条件下，改变ＰＨ值，研究底泥对水体的复磷。底泥中无机磷占大部份．ＰＨ值．ＤＯ（溶解氧）对湖水复磷影响显著，主要是释放ＰＡｌ和ＰＦｅ。
This paper dicusses the phosphorus forms in the lake sediments including:exhangeble,soluble,aluminium bonded,iron-bonded, calcium bonded and closed phosphorus and a part of organis phosphorus.The phosphorus in different forms are ettracted by the step extraction.At same time under andd anaerobic conditions.the recoyery of phosphorus from the sediment to water is studied with pH value changing. The results show that inorganic phosphorus takes the greatest part of the total amount,the release of phospho-rus is affected pH and DO obviously.
