摘要

[目的] 为了分析3个不同下垫面近地表风沙流结构差异及输沙粒度特征

为输沙模型的建立提供理论依据。[方法] 对策勒绿洲-沙漠过渡带风速梯度和输沙率进行野外观测

采用拟合函数回归方法分析。[结果] 在0-200 cm高度范围内

流沙地近地表输沙率或输沙通量与高度服从指数函数或对数函数关系

且拟合程度较高;半固定沙地近地表输沙率或输沙通量随高度服从指数函数关系

拟合程度中上等

稍差于流沙地;固定沙地输沙率随高度变化服从多项式函数关系

拟合程度中等-差。[结论] 平均风速较大时

流沙地、半固定沙地地表输沙率或输沙通量随高度变化多服从指数关系

且拟合程度好于平均风速较小的输沙阶段;近地表跃移、蠕移沙粒无论在垂向还是在水平方向上

离地表越高或离绿洲越近其各高度输沙率和沙粒平均粒径都有变小和变细趋势

在水平方向上流沙地输沙沙粒分选性依次好于半固定沙地、固定沙地

分选性多属于中等或中等偏上;所有输沙沙粒的偏度值分布在-0.06~0.05之间

越靠近绿洲输沙沙粒越细;所有跃移、蠕移沙粒峰态值分布在0.92~1.05之间

属于中等峰态。

Abstract

[Objective] In order to analyze the differences of sand flow structure and characteristics of grain size of sand transportation particles near ground surface on three different landscape types

which can be used by providing theoretical basis for setting up sand transportation models.[Methods] We carried out the field observation on wind velocity gradient and sand transportation rate on Cele desert-oasis ecotone

and fitted regression functions.[Results] There was an exponential or logarithm function relationship between sand transportation rate or sediment flux and height at the range from 0-200 centimeters above ground surface on mobile sandy ground. An exponential functional relationship was found between sand transportation rate or sediment flux and height near surface on semi-fixed sandy land and the fitting degree was moderate and well moderate degree which was a bit worse than that on shifting sandy ground. There was polynomial functional relationship between sand transportation rate or sediment flux and height near ground surface on fixed sandy land and the fitting degree was between medium degree and worse degree.[Conclusion] When the mean wind velocity was comparatively greater

an exponential relationship was always detected between sand transportation rate and height and the fitting degree was better than that in phases with slower wind velocity. Whereas on vertical or horizontal directions for sand saltation and creeping sand particles near ground surface

the sand transportation rate and mean grain size on different heights became smaller and finer with increasing distance to ground surface or shortening distance to oasis on horizontal distance. Sorting effect of sand transportation particles on shifting sandy land was better than that on semi-fixed and fixed sandy lands on horizontal direction

which were most belonged to moderately well sorted. The sand has became finer skewed when the sand transportation particles is nearer to the oasis. The skewness of all sand transportation particles including saltation and creeping particles is in the range between -0.06 and 0.05. The kurtosis is in the range from 0.92 to 1.05

which belongs to mesokurtic.
