摘　　要：盐沼潮滩作为滨海湿地的一个重要类型,为河口海岸地区提供了多种关键的生态服务功能,具有重要的社会、经济与生态价值,其地貌演变规律的认知是海岸带保护修复和科学管理的基础。回顾国内外近一个世纪以来针对潮滩动力地貌过程的研究工作,发现研究热点已逐渐从传统的研究潮滩水-沙-地貌相互作用过渡到探索植物、动物、微生物等生物作用与动力、地貌之间的互馈机制,涉及海岸动力学、地貌学、沉积学、环境生态学等多个学科,是典型的交叉学科前沿研究领域。归纳了盐沼植被与潮滩多种因子的相互作用,总结了常用的盐沼潮滩地貌演变模拟手段及取得的机理认知,并提出今后在生物作用、陆海耦合动力地貌模型研发等方面的科学问题和发展方向。As an important type of coastal wetlands,tidal flat-saltmarsh systems provide a variety of key ecosystem services for estuarine and coastal areas,and have important socio-economic and ecological values.The understanding of their geomorphological evolution is the basis of coastal zone restoration and scientific management.This review recalls previous studies on the evolution of tidal flat geomorphology.Research focused on tidal flat-saltmarsh systems has gradually changed from traditional geomorphology to biogeomorphology which involves disciplines such as hydrodynamics,geomorphology,sedimentology,ecology and biology.It is a typical interdisciplinary research field.The paper summarizes the interaction between saltmarshes and hydrodynamics,sediment transport,geomorphology,human activities,biological activities,and other relevant processes on tidal flat-saltmarsh systems.This study summarizes the current relevant models and understanding of the dominant mechanisms that play a role in the evolution of tidal flat-saltmarsh systems.Finally,some future research directions such as the description of biological activities and development of land-sea coupled biogeomorphological models are proposed.
