摘　　要：利用内蒙古70个气象站1961—2006年年平均气温资料,分析了近46年来内蒙古气温变化趋势。采用滑动t检验、Mann-Kendall和累积距平曲线3种检验方法对全区年平均气温进行检验分析,揭示了在50年时间尺度上,内蒙古气温存在明显的增暖突变的事实,突变点在1987年。并指出:气温突变后内蒙古气候显著变暖,与突变前相比有明显差异。Based on the annual mean temperature data of 70 meteorological stations in Inner Mongolia from 1961 to 2006,the trend of temperature change was analyzed in recent 46 years.The test analysis were conducted on annual mean temperature of whole area with the three methods of Moving t-test technique,Mann-Kendall methods and accumulated departure.It showed that： on the timescale of 50 years,there was an obvious truth of warming and abrupt change on the temperature of Inner Mongolia,abrupt change point was 1987.After the abrupt change of temperature,the climate of Inner Mongolia was warming obviously,compared with abrupt change before,there was obvious difference.
