中文摘要	对新疆巴里坤鸣沙山风成沉积物粒度进行了分析,并对其特征进行了探讨。结果表明:巴里坤鸣沙山风成沉积物以中沙为主,分选较好,偏度值接近0,峰态很窄。概率累积曲线揭示风成沉积物碎屑颗粒的主要搬运方式为跃移,所占比例为40%~95%。沿沙脊-山坡-山脚的方向,平均粒径逐渐变大,分选性变差,蠕移组分含量增加。粒度具有分形特征,分维值平均为0.94,与常见碎屑物质相比,处于较低的水平。分维值与标准偏差显著相关,说明分选程度会对分形特征产生影响。
英文摘要	Grain size of aeolian sediments from Balikun Mingshashan Desert,Xinjiang was analyzed,and its features were discussed in the present study.The results show that medium-size sands are the predominate component in the sediments.Frequency distribution curves of grain size of those deposits are nearly symmetrical, well-sorted and very leptokurtic.Probability cumulative curves reveal that the grains mainly move in the form of saltation,which accounts for approximately 40%-95%.Along the downward direction from sand ridge to the foot of the sand dune,mean grain sizes of the sediments increase gradually.Ratio of coarse component also elevates,but sorting of the grains becomes poor.The mean fractal dimension is 0.94,which is relatively low in comparison with some common detritus.A significant positive correlation between fractal dimension and standard deviation implies potential impact of sorting degree on fractal characteristics.
