【摘要】 洪泛湿地是洪水周期作用下形成的水陆交错关键带。水体的补给、径流、排泄等水动力过程驱动着湿地元素循环和生物演化，从而实现洪泛湿地的生态功能。洪水的周期性淹没造成湿地潜流带结构和渗透性的时空异质性，导致量化洪泛湿地水动力过程的不确定性。综述了洪泛湿地潜流带水动力过程的研究进展，从洪泛湿地沉积物-水界面动态变化的角度提出了未来洪泛湿地水动力过程的研究方向，旨在揭示洪泛湿地潜流带水动力过程对洪水脉冲的响应机制，丰富和完善湿地系统多环境要素耦合研究的理论和方法，为洪涝灾害导致的退化湿地生态功能恢复、洪水资源化利用及湿地的可持续发展提供科学依据。更多还原

【Abstract】 Floodplain wetlands are formed under the processes of flood cycles, and they are key zones where land and water interlace. Hydrodynamic processes such as recharge, runoff, and discharge of water bodies drive the elements cycles and biological evolution, thereby realizing the ecological functions of floodplain wetlands. Periodic inundation of floods results in significant spatiotemporal heterogeneity in the structure and permeability of the wetland hyporheic zone, leading to uncertainties in quantifying the hydrodynamic processes of floodplain wetlands. The research progresses of the hydrodynamic process in the hyporheic zone of the floodplain wetland are reviewed, and the future research directions of the hydrodynamic process of the floodplain wetland are proposed from the perspective of the dynamic change of the sediment-water interface of floodplain wetlands. The review aims to reveal the response mechanism of the hydrodynamic process in the hyporheic zone of the floodplain wetland to the flood pulse, to enrich and improve the theory and method of the coupling study of multiple environmental elements of the wetland system, to provide important scientific basis for the restoration of ecological functions of degraded wetlands caused by floods, flood resource utilization and sustainable development of wetlands.更多还原
