Abstract

The Crescent Spring is a special scenery,so the study on its formation and preservation attracts more and more attention. In this paper,the data observed by the field meteorological station and the total station were applied to analyze the short-term dynamic change of the mega-dunes around the Crescent Spring. Results showed that the mega-dunes were stable during the observation period,which was different from the former conclusions drawn from the interpreted results of perennial aerial photographs that the longitudinal dunes in the south moved northward,the pyramid dunes in the north moved southward,and the Crescent Spring was threatened. The crest line of the mega-dunes shifted in an oscillating way. Sand erosion or deposition occurred on the dune surface,which was closely related to the wind regime,sand sources,underlying surface,barriers,etc. The observation revealed that sand erosion occurred on the windward slope and sand deposition occurred on the leeward slope. The displacement laws of the mega-dunes around the Crescent Spring were revealed,which could be referred in protecting the Crescent Spring.

Key words： Mingsha Mountain and Crescent Spring; mega-dune; dune crest line; leeward slope; sand drift potential; Dunhuang
