Abstract:: Barchan dunes occur widespread on desert all over the world,and are one of the basic dune shapes.The studys about dunes shape’s parameter by researchers home and abroad indicated that the relationship between the height of dune and the width of dune’s horn are linear.Using the high precision date that measured in Badain Jaran desert and Tengger desert of Hexi and the data measured by predecessor in Minqin,The relationship between the height of dune and the width of dune’s horn is analyzed with least square method.It is indicated that they have the direct ratio relationship.Comparing with other 5 banchan dunes shape’s parameter date in Kumtag Desert,it is found that the relationship between the dune height and the width of the dune’s horn can be different in different geography and nature.And this direct ratio can be a geomorphologic parameter which describe the character of banchan dunes.
