再悬浮过程对磷在颗粒物上的分配过程的影响及生态环境效应
|
摘要
磷(P)是重要的生源要素,磷循环属于沉积型循环,颗粒物是沉积物最基本的组成单位和物质载体。同时,磷在颗粒物-水界面的分配和转化过程最为活跃,而水动力扰动则是颗粒物分选和磷再分布的驱动力。研究再悬浮过程中磷在颗粒物上的分配,对了解磷在水生态系统中的迁移转化,以及进一步管理和调控流域富营养化和渔业生产具有重要参考意义。
Phosphorus(P)is an important source element and cycling in sedimentary.Particulate matter is the most basic component of sediment and material carrier.At the same time,the distribution and transformation process of P at the sediment-water interface is the most active,while the hydrodynamic disturbance is the driving force for particle sorting and P redistribution.Therefore,researching the distribution of phosphorus on particulate matter during resuspension has important reference significance for understanding the migration and transformation of phosphorus in aquatic ecosystems and further managing and regulating water eutrophication and fishery production.
