摘　　要：利用NCEP/NCAR再分析资料,分析内蒙古地区的水汽资源时空分布特征,探讨该地区水汽通量及收支等特征。结果表明:内蒙古地区年平均可降水量为10~15kg·m^(-2),夏季可降水量最大,冬季最少。全区主要受偏西或西北向的水汽通量影响,除东北部外,全区大部地区为水汽辐散。夏季,东、西部水汽输送特征有很大差异,东部受西南风水汽通量控制,且为水汽辐合。全区年均水汽输入为13.74×107kg·s^(-1),夏季的水汽输入量最多,高达21.93×107kg·s^(-1),秋季最少。全区年均水汽输入量约4.33×10^(15)kg,年均降水量为3.34×10^(14)kg,降水仅占全部水汽输入的7.7%,空中可开发利用的水汽资源很丰富。By using NCEP/NCAR reanalysis data, the temporal and spatial distribution characteristics of water vapor resources in Inner Mongolia area are analyzed, the water vapor flux and the characteristics of the budget are discussed. The results show that the average annual precipitable water in Inner Mongolia is 10～15kg·m-2 . The whole region is mainly affected by the water vapor flux from the west or the northwest, except for the northeast, most of the region is water vapor divergence. In summer, the characteristics of water vapor transport in the East and West are very different. The eastern part is controlled by the southwest wind water vapor flux and the water vapor convergence. The average annual water vapor input is 13.74×107kg·s-1, and the maximum amount of water vapor input in summer is up to 21.93×107kg·s-1. The region＇s average annual water vapor input is about 4.33×1015kg and the average annual rainfall is about 3.34×1014kg. Precipitation accounted for only about 7.7% of the total water vapor input, therefore, the development and utilization of water vapor resources are very rich.
