摘　　要：本研究以内蒙古阿拉善地区沙尘暴源区为研究对象，利用该区所辖3个旗县范围内的巴彦浩特、拐子湖、中泉子、吉兰太、诺尔公、头道湖、锡林高勒、阿右旗及额济纳旗等9个气象台站1961年-2004年的沙尘暴逐次统计数据和土地利用、沙漠化数据进行分析，探讨了土地利用和土地沙漠化与沙尘暴发生的关系。结果表明：阿拉善地区沙尘暴的发生具有很大的时空差异，沙尘暴发生日数的代际波动较大；沙尘暴出现日数的变化是特定气候变化的反映，下垫面的持续恶化是该地区沙尘暴天气持续增加的主要原因之一，下垫面与沙尘暴发生关系密切，戈壁地表不利于沙尘暴的发生，植被覆盖度的增加对沙尘暴有明显的抑制作用。The aim of this study was to investigate the relationship between land use and desertification and sandstorm occurrence based on the source of sandstorm in Alashan region of Inner Mongolia, using sandstorm＇ s successive statistic, land use and desertification data obtained from nine weather stations ： Bayanhot, Guaizai Lake, Zhongquanzi, Jilantai, Noergong, Toudao Lake, Xilingaole, Mashan Right County, and Ejina County, of the three counties from 1961 to 2004. The results indicated that the occurrence of sandstorm in Mashan region presented significant difference in time and space; the number of sandstorm changes in the inter - generation presented a great fluctuate; the number of sandstorm changes presented a reflection under specific climatic condition; the continued deterioration of the underlying surface was one of the main reasons of the increasing sandstorm occurrence ; there was a close relationship between the underlying surface and sandstorm occurrence; the Gobi surface was not beneficial to sandstorm occurrence; sandstorm occurrence was restrained with the increase of the vegetation coverage in the region.
