| 摘 要： | 利用鄂尔多斯地区8个旗县中心站点1961—2011年的逐月平均气温序列资料,采用趋势变化、滑动t检验等方法,分析了鄂尔多斯气温的空间分布特点和时间特征,并且检验了51a来鄂尔多斯年平均气温的突变情况。结果表明:鄂尔多斯地区气温空间分布呈现西中部偏低,其余地区偏高的格局,气温51a增暖特征显著,并且在51a的时间尺度上,年平均气温经历了两次突变。

| Abstract: | Based on the annual mean temperature data which collected from 8 stations of Ordos from 1961 to 2011 years, by adopting the method of Trend and Moving t-test. The spatial-temporal distribution characteristics of temperature were analyzed in Ordos, and the mutation of annual average temperature was tested in the past 51 years. The results showed that Ordos annual average temperature was warming significantly, Midwest was cooler than the mean, the other was warmer. Ordos annual average temperature in 1987and 2001experienced cooling into warming mutation. |
