| 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（Pa-t），可溶性磷（Psol），经结合态磷（Pu），铁结合态磷（PFc），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，□□□□□□氧）对湖水复磷影响显著，主要是释放PAf和PFc。

| Abstract: | 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. |
