摘　　要：采用哈密地区6站1975—2014年逐日地面水汽压和降水量资料,计算了哈密各站的大气可降水量、有效空中水资源量、自然降水产出率和人工增水潜力值,并分析了各量的时空分布特征。结果表明：哈密地区年平均整层大气可降水量为2560~4327 mm,年均有效空中水资源量约为232~828 mm,占整层大气可降水量的1/4~1/10;年均自然降水产出率在9%~28%,自然降水产出率与降水量成正比关系。哈密地区的年人工增水潜力理论计算值在844~2399 mm之间,潜力值在夏季最大,巴里坤和伊吾明显多于其它区域。Using the ground water vapor pressure and precipitation data from 1975 to 2014 of 6 stations in Hami area, the atmospheric water vapor, effective air water resources, natural precipitation ratio and artificial precipitation enhancement potential were calculated, and their spatial and temporal distribution were analyzed. The results showed that the annual mean atmospheric precipitation water vapor in Hami is about 2560-4327 mm. The annual mean effective air water resources is about 232-828 mm, and accounts for 1/4-1/10 of the whole atmospheric precipitable water vapor. The annual mean natural precipitation rate is about 9%-28%, and it is positively correlated to precipitation. The theoretical value of annual artificial water potential is 844-2399 ram, and it reaches the peak in summer, and the poteatial is significantly much more in Barkol and Yiwu than that of other regions.
