摘　　要：根据近50年来山西省18个气象基准站1960—2004年间的逐月气温、降水量和山西气象观测台(太原站)1966—2005年的逐月太阳辐射资料的统计,对山西省的气候变化进行了较系统的分析。结果表明,近50年来山西省气温上升趋势明显,而且在1990年有一次明显的跃变(1990年的累积距平等于零),年平均温度以0.25℃/10a的幅度上升;降水的年变化呈下降趋势,平均以18.7mm/10a的幅度下降,在1990年也有一次跃变;年总太阳辐射量亦呈下降趋势,且在1982年有一次明显的突变,年平均太阳辐射总量以每10年238.9204 MJ/m2的幅度下降。1982年以前以正距平为主,1982年后以负距平为主,且跃变的幅度较明显。This paper aimed at making a systematic analysis in the climate change in Shanxi Province,according to a study of the material about the air temperature and precipitation during the near 50 years （1960--2004） from 18 meteorological datum stations in Shanxi Province,and a specific analysis about the solar radiation from 1960 to 2005.It was clear that during these near 50 years the air temperature in Shanxi Province had an obviously increasing tendency especially in 1990,when it met a great change the year average temperature increased by 0.25℃ per 10 year.The precipitation in these years was in a descending tendency by 18.7mm per 10 years every year and similarly there waa a great change in 1990. The overall year solar radiation in Shanxi was also in a dropping tendency, this situation was particular in 1982, when the year solar radiation descended by 238.9204 MJ per square meter per 10 years. Before 1982,this change was mainly positive anomaly method and after 1982,it was mainly negative anomaly method and the degree of change was very clear. Besides,human activities also had great influence on the climate change in Shanxi Province.
