Aeolian geomorphology is formed by wind power in arid, semi-arid, and even humid regions. It is the study of the characteristics of land surface patterns, spatial combinations, formation, and development. Wind regime controls aeolian geomorphology patterns, spatial combinations, and development. Near surface air flow and aeolian flow control the development and movement of dunes. Recently, the field has developed rapidly. This paper summarized recent progress in aeolian geomorphology patterns, wind regime, and dune morphodynamics based on aeolian geomorphology observation methods, analysis method and morphodynamics. The new terrain observation techniques, such as Total Station and three dimensional terrain scanner, provided accuracy terrain data for morphodynamics study. Meanwhile, three dimensional sonic sensor measured high frequency field wind velocity data, which gave more information on the relationship between terrain and near surface air flow. However, the analysis method, such as the relationship between wind regime and dune types, high frequency wind velocity data and reciprocal relationship between dune pattern and near surface air flow, is still not solved.
