| 摘 要： | 利用1960-2008年山西省65个气象站的气温资料，采用线性倾向估计、滑动平均法、小波分析和突变分析等方法，分析了近49a来山西省气温变化的特点和规律。结果表明：山西省年及四季气温均呈上升趋势,气温倾向率分别为0.25℃/10a、0.31℃/10a、0.04℃/10a、0.19℃/10a和0.43℃/10a。山西省年平均气温与秋季气温存在准15a及5-10a的周期，春、夏两季气温主要以5-10a的周期变化为主，冬季气温主要存在准15a的周期。山西省年平均气温以及春、冬两季气温均发生了突变,突变开始时间为1993、1997年和1988年。

| Abstract: | According to the temperature data at 65 weather stations from 1960 to 2008 in Shanxi province,the characteristics of air temperature change were analyzed using the methods of a linear trend analysis,a moving average and a wavelet analysis.The results indicated that the annual average air temperature and seasonal air temperature are in the increasing trends,and their tendency rates are 0.25 ℃/decade,0.31 ℃/decade,0.04 ℃/decade,0.19 ℃/decade and 0.43 ℃/decade.There is a 15-year quasi-cycle and a 5-10 years cycle for the annual mean air temperature and autumn air temperate,respectively.The cycles of spring and summer air temperature are mainly 5-10 years,while the cycle of winter air temperature is 15 years.There exist the abrupt changes for the annual mean air temperature,spring and winter air temperature.Their abrupt changes occur in 1993,1997 and 1988,respectively. |
