摘　　要：利用1960～2012年间内蒙古苏尼特右旗赛罕塔拉地区气温和降水数据,分析了这一荒漠草原典型地区的气温和降水变化。结果表明:这50多年间,该地区年均气温虽有波动,且2007年后稍有下降,但整体上升趋势明显,并存在突变现象,气候倾向率为0.3℃/10a;春、夏、秋和冬季平均温度在年际间波动情况各有不同,但整体上升趋势均显著,特别是秋、冬季表现更明显。年降水整体上趋势不明显,但20世纪90年代以来,波动幅度增大,并存在变率突变现象。The air temperature and precipitation data in Saihantala of Inner Mongolia during 1960 to 2012 were analyzed. For the annual temperature, it showed significant increasing trend during 53 years with the slop of 0. 36℃/10a, though the temperature was fluctuating over years and going down after 2007. An abrupt change of air temperature was examined. The fluctuation of temperature in spring, sum- mer, autumn andwinter was different. The significant increasing trends of temperature were observed for every season, especially in autumn and winter. The annual precipitation had no obvious trend, but the fluctuation became stronger after 1990s and the abrupt changes in the variance existed.
