摘要:
对塔克拉玛干沙漠及其大气降尘点的粒度参数进行了分析计算，结果表明：风沙天气过程中，塔中沙漠地区平均粒径Ф值较小，标准偏差较小；肖塘沙漠过渡带平均粒径Ф值较大，标准偏差较大。肖塘沙漠过渡带粒度曲线分布形态左偏；塔中沙漠地区曲线分布形态右偏。肖塘沙漠过渡带的峰度值较大，塔中沙漠地区较小。塔里木盆地及其周边地区平均粒径Ф值为2~6，为细沙、极细、粗粉沙、中粉沙或者是其混合体。
Abstract:
Analysis on the grain sizes of atmospheric dust and sands in the Taklimakan Desert. The results showsed that Ф values and standard deviation in sandy and dust weather inTazhong was lower. However, those of Xiaotang transition zone was higher. The distribution shape of Xiaotang transition zone was left deviated, and that of Tazhong was right deviated. The kurtosis of Xiaotang transition zone was higher than that of Tazhong desert area. The mean grainsize (Ф value) of Tarim basin and its surrounding area is 2～6, consisting of fine silt, very fine silt, coarse silt, medium silt and their mixture.
