内蒙古自治区地处季风气候边缘区。对该地区气候生产潜力的动态分析表明:区域内气候生产潜力年际变率大,其中水分限制作用突出的地区变率尤大。利用自然正交函数对气候生产潜力的时空分析还揭示出:区域内生产潜力的变化在时间上具有同步性,在变幅上具有地区差异性,在空间上,东西方向具有反相性。

Inner-Mongolia is located in the peripheral area of the Monsoon climate region. The dynamic analysis shows that the climatic productive potential there has great variation from year to year, especially in the region where water is a dominant limiting factor. Using the empirical orthogonal function (EOF),the result of the temparal and spatial analysis reveals that the variation of the productive potential synchronizes with time and has regional difference in variation amplitude and that its variation in the east is opposite to that in the west.
