摘要
以内蒙古中西部地区的地貌格局为背景,探讨了该地区沙尘暴日数分布的地貌特征。通过比较地貌类型、地形剖面线与沙尘暴日数分布的关系,以及统计不同地貌类型区的沙尘暴日数特征,得出的结论为:在内蒙古中西部地区,沙漠边缘及沙地区沙尘暴日数最多,高平原区次之,山地丘陵区较少,平原区最少。
A study was performed to analyze the topographical features of the sandstorm days with a background of the geomorphic pattern in western and central Inner Mongolia. By comparing the relationship of geomorphic types, sectional lines of the terrain and distribution of sandstorm days, and analyzing the characteristics of sandstorm days for different regions of geomorphic type, it is concluded that, the sandstormoccurring days in western and central Inner Mongolia can be listed from the most to the least in the following order: desert border and sands, higher plain, mountainous and hills, and lastly the plain regions.
