Abstract

Abstract: The dustfall at different height and distance along leeward direction of the typical shifting sand dunes in the hinterland of the Ulan Buh Desert was studied by means of continuous spot observation and particle size analysis. The results show that the spatial variability of the dustfall is significant in the Ulan Buh Desert. The dustfall is mainly dominated by fine sand. Fine sand is gradually reduced with the increase of the distance along leeward direction of the typical shifting sand dunes. Silt and very fine sand increased rapidly with the increase of the distance along leeward direction of the typical shifting sand dunes. The average grain size of the dustfall is in the range from 2.5 Φ to 3.1 Φ, and it grows with the increase of the distance and the height along leeward direction of the typical shifting sand dunes. The sorting coefficient becomes worse with the increase of distance and height along leeward direction of the typical shifting sand dunes. The skewness coefficients is close to symmetry at 2 m height, and positive at 8 H distance when the height of sand dune is H. But at 0.5 m height, it is symmetrical at 0.5 H-1 H distance and positive skewed at 2 H-8 H distance along leeward direction of the typical shifting sand dunes. Kurtosis changes to narrow gradually with distance increase, and the change at 2 m height is later than at 0.5 m height. It can be assumed that the dustfall of the Ulan Buh Desert is mainly from the local material, and the proportion of material from the far sources and regional material is small. The proportion of material from the far sources and regional material (<70 μm) is positively correlated to leeward distance and mainly from the waste land in desert fringe area, the sediment of rivers and lakes, farmland region. But the proportion of local material (>70 μm) is negatively correlated to downwind distance and mainly from the short distance transport of airflow in underlying surface of dune.
