摘　　要：强潮河口在我国及世界都有广泛分布,其以强动力、高混浊和滩槽冲淤复杂多变的特性明显有别于一般潮汐河口.近几十年来,国内外许多学者在强潮河口混合过程、细颗粒泥沙运动、滩槽沉积地貌过程、河口综合治理等方面取得了一定进展.在系统总结近年主要相关研究成果的基础上,着重讨论了强潮河口的混合类型与特征、最大浑浊带的形成发育与主因、潮滩地貌的动力影响因素与演变过程、河口综合治理的特点与人类活动引起的水沙变异等问题,并指出多学科交叉、数学物理模拟与预报、水沙动力机理与过程的量化等方面是未来研究重点与方向.Vast macrotidal estuaries can be found widely at home and abroad. The macrotidal estuaries are characterized by stronger hydrodynamic force, higher suspended concentration and complicated evolution of seabed, hence is distinctly different from other ordinary tidal estuaries. In the last decades of years, many researches on the mixing process, fine sediment transport, sedimentary processes of shoal and pool and comprehensive regulation have been made for some macrotidal estuaries. On the basis of these results, the estuarine mixing type and characteristics, and the formation and development of maximum turbidity zone, and the morphodynamics of intertidal mudflat evolution, and the effects on hydrodynamic and sediment environment caused by estuarine regulation are analyzed in detail. Finally, it is pointed out that the multi-disciplinary study, the numerical simulation and prediction by use of mathematical models, and the quantization of the hydrodynamic and sedimentary processes are the focal issues in future.
