Abstract Hanmagang Desert is an important section of the Tengger Desert and lies in the southern region of the Tengger Desert. The most important landforms in the Hanmagang Desert are the aeolian geomorphology and fluvial landform coexisted and paralleled each other for south-north direction. The aeolian landforms are sand dunes and lie in the higher latitude, but the fluvial landforms are gully and lie in the lower latitude. The main dune types are barchan chains, reversing dunes and shrubbery dunes. Barchan chains and reversing dunes are distributed like partial mulching, shrubbery dunes are distributed in the gully. Threshold wind direction are mainly northwest and then southeast. Wind energy environment belongs to lower, the resultant sand drift potential direction is 282-331, the directional index is intermediate. Sediment particle are coarser over dune surface, and then lower layer of crust and crust and there are similar rule of the sorting. The material for the Hanmagang Desert formation was from the Shiyanghe River and the Qilian Mountain. According to the field observation and previous studies, we could build a model for the formation and development of the Hanmagang Desert:the great lakes period, the lakes dry up period, the desert formation and development period and the atrophy period.
