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.

Key words: drylands, aeolian-fluvial interactions, riparian dune, geomorphologic processes
