Abstract In the paper, the distribution characteristics of complex mega-dunes in the Badain Jaran Desert are described by the method of nearest neighbor analysis, and the main cause and the influencing factors of the complex mega-dunes are analyzed and deduced. The results show that the change of the nearest neighbor index R, elevation and floor area of complex mega-dunes maintain increasing trend from the west to east in the Badain Jaran Desert, and the R is 1.29-1.63. Correlation analysis shows that the developing of complex mega-dunes about the degree of homogeneity is not affected by the elevation of the interdune in the Badain Jaran Desert. The spatial distribution adheres to self-organization well, and the wind is the main power to make and maintain the complex mage-dunes which have enormous height and self-organization in the Badain Jaran Desert.

Key words: Badain Jaran Desert nearest neighbor analysis self-organization space distribution
