Abstract: Dune geomorphology is one of important issues in aeolian geomorphology. Reversing dune has two leeward slopes, and forms under two reversed wind directions. There are transverse dunes formed under primary wind direction, and the dune crest moves to primary wind direction under reversed wind direction. The reversing dunes can form under anywhere there are reversed wind directions. In this paper, the developing reversing dune on a flatted shifting surface in the southeast Tengger Desert were selected to study the dune geomorphology development processes. The windward slope and leeward slope were measured in the field conditions. The result indicated that the reversing dune development can divided into three stages:transverse dune, transition and reversing dunes. During the different development stages, the windward slope and leeward slope obviously changed.

Key words: Tengger Desert, reversing dunes, geomorphology
