| 摘 要： | 根据内蒙古阿拉善地区1961—2000年40年的沙尘暴、扬沙资料，分析了其气候学特征、地理特征、季节特征以及年际、年代际变化特征。结果表明．近40年来阿拉善地区沙尘暴出现日数在减少。但是进入20世纪90年代，阿拉善北部地区沙尘暴出现日数却呈波动增加趋势。沙尘暴出现日数的变化是特定气候变化的反映，下垫面条件的持续恶化也是该地区沙尘暴天气持续增加的原因之一。 |

| Abstract: | Based on the observed duststorm data in Alashan region of Inner Mongolia from 1961 to 2000, the climatic characteristics of duststorm in this region was analyzed, especially the geographical distribution and seasonal, interannual and interdecadal characteristics. The results showed that the duststorm day in Alashan region decreased in the period of the last 40 years, but the duststorm day were increasing as wave in northern Alashan in 1990's, the variation of the duststorm day numbers are responsive to some special climate variations, and the continued deterioration underlying surface condition is one of an important reason of increasing duststorm day numbers in this region. |
