摘　　要：利用计算的天山及周边地区大气含水量序列的方差值和降水转化率,分析了天山地区空中水资源的稳定性和可开发性。结果表明:空中水资源的稳定性与大气含水量的多少有密切关系,大气含水量低的地区,空中水资源稳定,而大气含水量高的地区,空中水资源不稳定。夏季是四季中方差最大的季节,稳定性较差;冬季是大气含水量方差最低的季节,特别是山区大气含水量稳定,秋季略高于春季。天山东部和西部地区的大气含水量方差明显要小,而中部地区较大。大气含水量的稳定性与海拔高度呈反相关。降水转化率与海拔高度密切相关,随着海拔高度上升,降水转化率增大。天山山区年降水转化率最大,伊犁河谷冬季降水转化率最大。The stability and exploitability of water vapor resource in Tianshan Mountains was analyzed based on the water vapor variance and precipitation conversion efficiency.The results indicated that the stable characteristics of water vapor content were closely related to the values of water vapor content. Water vapor content was stable in the low value region while it was unstable in the high value region. Maximum variance occurred in summer and the stability was low, the variance for winter was small and it was a bit higher in fall than spring. The variance in the eastern and western region of Tianshan Mountains was small and great in the center. Atmospheric moisture stability was negatively correlated to the altitude which was mainly related to the water vapor condensation level. Terrain height change was closely related to precipitation conversion efficiency, and the higher altitude,the more precipitation conversion efficiency. Precipitation conversion efficiency was the highest at the altitude of 2,000 meters around.
