| 摘 要： | 沙漠-河流过渡带是独特的地理单元，在世界主要沙漠中普遍存在，河岸沙丘地貌发育过程是其独特性的突出表现。一方面，河流通过提供物源和场所控制河岸沙丘地貌的发育过程与格局，另一方面，沙丘发育过程改变河道。本文回顾了沙漠与河流复合地貌过程研究取得的重要进展，包括沙漠与河流交互关系、沙漠和河流交互尺度以及河岸沙丘地貌形成与发育过程等。但水系变迁与沙漠演化、沙丘复杂性与河谷形态之间的关系，以及如何建构沙漠河岸风水复合地貌过程模型等问题，将是未来需要突破的难题，这有助于促进风沙地貌与流水地貌的高度融合，丰富沙漠科学和干旱区水文的理论体系。

| Abstract: | Desert-river transition zone is a unique geographical unit that prevails in the main deserts of the world. The complex geomorphic process of deserts and rivers is an outstanding manifestation of its uniqueness. On the one hand, rivers control the development process and pattern of aeolian landforms through the provision of source and place. On the other hand, dune development changes the course of the river. The important progress made in the study of the complex geomorphologic processes of deserts and rivers was reviewed, including the interactions between deserts and rivers, the interaction scales of deserts and rivers, and the formation and development processes of dunes of river bank. However, issues such as the evolution of river systems and the evolution of deserts, the relationship between dune complexity and river valley morphology, and how to construct desert riparian geomorphologic process models for aeolian-fluvial interactions issues will be challenges that need to be broken in the future. This will help scientifically understand the aeolian-fluvial interaction in arid regions. The process and mechanism promote the high integration of aeolian landforms and fluvial landforms, and enrich and improve the theoretical system of desert science and hydrology in arid regions. |
