| 摘要: |
| 生物地貌学研究生物过程和地貌过程之间的双向交互作用，是一门新兴的交叉学科。早期的生物地貌学关注陆地生态系统，近期海岸带成为生物地貌学研究的热点地区，尤其是滨海湿地（如盐沼、红树林）成为研究生物地貌学过程和机理的重要区域。本文回顾了生物地貌学研究的概念、历史发展和方法，选取滨海湿地作为生物地貌学的主要研究对象，并就其研究方向、重要因素以及核心机制展开综述。最后对生物地貌学在海岸带生态系统修复工作中的应用进行梳理，分析了生物地貌学在红树林修复、滨海盐沼湿地修复和互花米草入侵防控上的应用展望。 |

| Abstract: |
| Biogeomorphology, a recently developed multidisciplinary study field, tends to focus on some aspects of two-way linkages between biological (ecological) and geomorphological processes. Previous works focused on biophysical feedbacks in terrestrial environments. However, coastal regions recently have become a hotspot for biogeomorphological studies. In particular, coastal wetlands, such as saltmarshes and mangroves, provide ideal places for this type of studies. The aim of this contribution is to provide the state-of-the art for biogeomorphological studies based on a literature review in the light of coastal wetlands. The review starts with a brief introduction of the history of biogeomorphology. Some key concepts and definitions are described to form the base of the overall knowledge. A gap between large-number statistical study by ecologists and small-number case studies by geomorphologist was discussed and a framework of methodology to bridge this gap was proposed. The main advances in biogeomorphology studies were summarized along with key elements and mechanisms controlling the development and succession of intertidal ecosystems. Ecological restoration practices in three typical coastal wetlands, including mangroves, coastal saltmarshes, and the invasion of Spartina, were explicitly deliberated, as the application extension and knowledge transfer of biogeomorphology. The last part presents an overall summary and the perspectives in the field of biogeomorphology. |
