摘　　要：为进一步揭示中国北方地区气候变化特征、基于不同尺度开展气象灾害分析预测,文中利用呼和浩特市赛罕区国家一般气象站1951-2010年日平均气温、平均日最高气温、平均日最低气温数据资料,详细分析了60年来呼和浩特市区气温随时间的变化趋势特征、不同季节的气温变化规律,并采用t检验法对这期间的气温突变状况进行了定性分析。结果表明:1951-2010年呼和浩特市区气温呈明显上升趋势,且平均日最低气温的增温态势比日平均气温和平均日最高气温更加显著;冬季增温幅度大于其它季节;20世纪80年代中后期呼和浩特市区气温出现了显著的变暖突变,冬季发生变暖突变早于其它季节;近60年来呼和浩特市区的变暖时间与华北及东北地区同步,早于中国及全球平均水平,且升温态势更为剧烈。To shed light on the characteristics of climate change in the Northern area of China,and to promote the meteorological disaster forecast based on different scales,we analyzed the variation characteristics of temperature trends over time,variation trends of temperature in different seasons,and the abrupt temperature change within this period with t- test method by using the data information of daily average temperature,daily average maximum temperature and daily average minimum temperature during 1951- 2010 that were monitored by the general national weather station in Saihan district of Hohhot city. The results showed that the temperature symbolized an obvious rising trend,and the calefacient tendency of daily average minimum temperature was much more significant than that of daily average temperature and daily average maximum temperature. The increasing intensity in winter was the most severe among four seasons. An obviously abrupt change of warming was occurred in the middle and the late years of the 20 th century in Hohhot city,and it was earlier that the abrupt point of warming occurred in winter than in the other seasons. The warming abrupt point in Hohhot city was synchronous with that in northern and northeast China in past 60 years,which was earlier than the average levels in nationwide and worldwide,furthermore,the calefacient tendency in Hohhot was much more violent.
