沉积物-水间磷迁移转化过程及生物可利用性研究进展

Review on the Transformation of Phosphorus in Sediment-water Interface and the Bioavailability of Phosphorus

磷是浅水湖泊富营养化产生的关键性元素,在沉积物-水中以多种形式存在,并具有沉积型循环特点。水动力导致的沉积物悬浮、沉积物-水之间理化性质的变化、水生动植物活动等因素都会引起沉积物-水间磷的迁移转化和赋存形态变化。本文在介绍沉积物-水中磷赋存形态与迁移转化及影响机制的基础上,对水生态系统中容易被生物利用或者被生物自身行为影响后容易被利用的生物可利用磷的存在形态和研究方法进行了讨论,可为湖泊富营养化修复及水华预测提供有力依据。

Phosphorus is the key element of eutrophication and exists in various forms in sediment-water interface.The factors such as sediments resuspension and activities of aquatic animals and plants can lead the release of phosphorus from sediment-water interface.By introducing the forms,migration and transformation of phosphorus in sediment-water interface,the author will discuss the influencing factors and bioavailability of bioavailable phosphorus,and provide a strong basis for lake eutrophication restoration and algal bloom prediction.
