通过最邻近距离法定量描述了巴丹吉林沙漠高大沙山空间分布特征,分析和讨论了巴丹吉林沙漠高大沙山的主要成因和影响因素。结果表明:研究区内高大沙山空间分布的均匀程度整体上呈现出由西向东逐渐增大的趋势,而东南部靠近雅布赖山地区略有降低,最邻近指数R主要分布在1.29~1.63。沙山底面积和沙山绝对高度在空间上同样呈现出由西向东逐渐增大的趋势,但巴丹吉林沙漠高大沙山空间分布均匀程度的发展并不直接受到所在地海拔的影响。巴丹吉林沙漠高大沙山在空间分布上具有较高的自组织特征,而风力作用是塑造和维持巴丹吉林沙漠高大沙山巨大高度与自组织排列特征的主要力量。
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.
