依据阿勒泰地区1961-2011年的逐月气象观测资料,采用目前常用的Thomthwaite Memorial模型计算了气候生产潜力.结果表明,阿勒泰地区的气候生产潜力为西部、北部最大,东部居中,南部的福海县最小,最大值与最小值相差达40％,空间分布不均；阿勒泰地区的气候生产潜力从20世纪60年代以来,总体呈现增加趋势,尤其是2000年以来,达到年代最大；阿勒泰地区气候生产潜力与年降水量有极好的正相关性,降水量是制约气候生产潜力的最主要的气候因子；气候生产潜力越大的县,变异系数越小,年变化越小,稳定性也就越好.%Based on the monthly meteorolgical observation data in Altay region during 1961-2011,Sanz Witt Memorial (Thomthwaite Memorial) model is used to calculate the climate potential productivity.The results showed that the climate potential productioity is the maximum in the western,northern region,the eastern region median in minimum,Fuhai county in southern region with 40％ difference between the maximum and the minimum and the spatial distribution is heterogeneous;the climate potential productivity has increases in Altay region since 1960s,especially since 2000 year,reaching the age of maximum; there is an excellent positive correlation between climate potential productivity and the annual precipitation in Altay region and precipitation is the most important climatic factors of constraint for the climate potential productivity; the larger counties of the climate potential productivity,the smaller the coefficient of variation is; annual changes is smaller,stability is better.
