中文摘要	以分维为工具，以分维数为中介参数刻画巴丹吉林沙漠高大沙山典型区风沙地貌的形态特征，研究发现，该区星状沙山多单独分布，其沙山高度较综合型星状沙山及复合型星状沙山小，一般多在100～200m之间，形态相对简单，因而其分维数较小（D＝1．042462）。综合型星状沙山，为在巨大的沙山体上迭置有次一级的星状沙丘其规模小于复合型星链状沙山，高度多达200～300m，该类型沙山形态结构较星状沙山复杂，因而其分维数高于星状沙山（D＝1．119346）。复合型星链状沙山，是构成该区域高大沙山的主体，其相对高度大于300m，平均为309．43m，最高可达465m，沙山形态结构颇复杂，在其巨大的沙山体上迭加有许多相同类型的次一级沙丘及古沙丘，规模也较综合型星状沙山大，因而其分维数最大（D= 1．148164）。
英文摘要	This paper, with fractal as the tool and using fractal dimension as the parameter, studies the morphologi cal features of aeolian sand landforms in typical megadune area of Badain Jaran Desert. It has been found that star megadunes in the area are mostly isolatedly distributed and they are smaller than the complex star megadunes and compound star dunes, with a height ranging from 100 ~ 200 m. Their shapes are relatively simple, with smaller fractal dimension ( D = 1. 042462 ) . Complex star megadunes are huge sand mountains with secondary star dunes superimposed on them. They are smaller than the compound star megadune chain and mostly 200 ~ 300 m in height. Their shapes are more complex than those of star megadunes, and their fractal dimension is higher than that of star megadune (D = . 119346). Compound star megadune chains constitute the main body of huge sand mountains in the area; they are generally higher than 300 m, with a mean height of 309. 436 m and a maximum height of 465 m. They have very complex shapes, with many secondary and older dunes of same type superimposed on them. They are larger than star megadunes and therefore have larger fractal dimension (D - . 148164) .
