摘　　要：泥沙颗粒对水体中的磷具有较好的亲和能力,河湖中的水沙运动可以改变磷的赋存状态并在一定条件下造成水体富营养化等生态环境问题。综合近年研究成果,目前关于河湖泥沙对磷的迁移转化作用研究存在研究内容局限、作用机理分歧、数学模型不全面等问题,且多为宏观层面研究。有必要在实验技术创新的基础上探讨水沙微界面吸附,并结合生态作用完善复杂条件多因子耦合对泥沙迁移转化磷的理论研究。Phosphorus has st rong affinity to react with sediment part icles. The motion of flow and sediment can change the occur-rence forms of phosphorus that may cause such environmental problems as eut rophication in rivers and lakes under certain con-ditions. The recent st udies were analyzed, which suggested that there are some limitat ions in the research cont ents, cont roversy of mechanism, and incomplete mathematical models for the transport and transformation of phosphorus in rivers and lakes, and previous studies are mainly on the macroscopic level. Further studies should be focused on the exploration of micro-adsorption betw een w ater and sediment interface on the basis of experimental technology innovat ion, and theoretic research of phosphorus transport and t ransformation on the coupling function of multiple factors under complicated conditions.
