【摘要】：鉴于侧岸潜流带中发生着强烈的生物地球化学作用,其独特而复杂的水动力特性对水生生态系统及生态环境有重要作用。通过分析总结前人对侧岸潜流带所做的研究,阐明了侧岸不同方向上潜流交换过程及其产生机制,分析了影响侧向潜流交换过程的主要因素(包括地形条件、沉积层特性、水文地质条件、河道工程、河岸植被条件),阐述了侧向潜流交换过程对溶质、颗粒和生态环境的影响。最后对侧向潜流交换今后的研究提出了一些建议。
[Abstract]:In view of the strong biogeochemical processes in the lateral subsurface flow zone, its unique and complex hydrodynamic characteristics play an important role in aquatic ecosystem and ecological environment. By analyzing and summarizing the previous researches on the subsurface flow zone of the lateral bank, the exchange process of the subsurface current in different directions of the lateral bank and its producing mechanism are expounded, and the main factors affecting the exchange process of the lateral subsurface flow are analyzed, including the topographic conditions, the characteristics of the sediment layer. The effects of lateral subsurface flow exchange process on solute, particle and ecological environment are discussed in this paper, including hydrogeological conditions, river engineering and riparian vegetation conditions. Finally, some suggestions for the future research of lateral subsurface flow exchange are proposed.
