利用1961—2010年巴彦淖尔市5、10、15、20cm各浅层逐月平均地温,采用气候倾向率和累计距平气候统计方法,分析巴彦淖尔市各浅层地温年、月变化趋势及气候异常等特征。结果表明：各层年平均地温以0.396~1.237℃/10a的升温率显著上升。年代变化趋势存在共同的特征：20世纪60年代初期至中期变化平稳,60年代末期至70年代初期处于50a以来的低温期;70年代中期至21世纪初各浅层平均地温在波动中上升,其中21世纪初期处于50a以来的高温期。巴彦淖尔市近50a各浅层月平均地温4—10月异常年份较多,且异常偏暖年份明显多于异常偏冷年份,就年平均地温而言,无异常年份。

sing 5,10,15,20cm average soil temperature month by month in Bayannaoer City from 1961 to 2010,montly and yearly variation trends and climate anomalies characteristics were analyzed by climate trend rate and cumulative anomaly climate statistical method. The result indicated that average soil temperature in each layer significantly increased.Heating rate is 0.396-1.237~C/10a. Age trends have common characteristics： The soil temperature changes steadily in the 1960＇s initial stage till medium term, The late 1960s till the early 1970s is in the low-temperature phase in the recent 50 years; The shallow average soil temperature rose with fluctuation from the mid-1970s to the early 21st century, and the early 21st century is in the high-temperature phase in the recent 50 years. Many unusual years of the shallow layers monthly soil temperature appeared from April to October in Bayannaoer City in the recent 50 years, and the exceptionally warm years are more than exceptionally cold years. There is no abnormal year in the annum average soil temperature.
