平原河流水沙界面生源物质迁移转化过程及水环境调控的研究进展

Advances in biogenic elements transport at the interface of stream-streambed and water environmental control in the plain river

  • 摘要: 生源物质作为影响水质的重要因素,其在河流中的迁移转换一直倍受关注。水沙界面物质交换过程受众多环境和水动力因素的影响,过程极其复杂,不仅影响着河流生源要素的通量演变规律,还关系到河流水环境问题。为探究水沙界面生源物质迁移转化过程及作用机制,结合国内外研究最新进展,对泥沙颗粒与生源物质的微界面作用、水沙界面对生源物质的迁移转化作用、水流条件对泥沙吸附解吸生源物质作用机理进行总结和概述,总结阐述了河流水质模型和闸坝泵条件下的水环境调控模型,最后指出平原河流水沙运动对生源物质输运作用机理及水环境调控。针对上述已有的研究成果和存在不足,对今后研究方向提出展望。

     

    Abstract: As an important factor affecting water quality,the migration and transformation of biogenic elements in rivers have attracted much attention. The process of mass exchange at the water-sediment interface is affected by many environmental and hydrodynamic factors,and it is extremely complex,which not only affects the flux of river biogenic elements but also relates to the water environment. In order to explore the migration and transformation process and mechanism of biogenic elements at the water-sediment interface,this paper summarizes the micro-interface mechanism of sediment particles and biogenic elements,the migration and transformation of biogenic elements at the water-sediment interface and the influence of flow conditions on sediment adsorption/desorption of biogenic elements. The water quality model of the river and the water environment regulation model are described under the condition of sluice and dam pumps. Finally,the influences of sediment transport on the transport of biogenic elements and water environmental regulation is pointed out in plain rivers. Furthermore,future research directions are also outlined.
