| 摘 要： | 文章利用1971—2017年土默特左旗的气温资料,采用线性趋势法、变异系数法、t检验法,对土默特左旗与农事活动相关的节气气温变化特征进行了分析。结果表明:年平均最高气温、年平均最低气温、年平均气温曲线的走势是一致的,但顺序发生了变化;谷雨、小满、夏至、小暑、立秋、处暑、白露的年平均气温呈显著的升高趋势,说明以上节气的年平均气温总体上是明显升高的,年平均最高气温的谷雨、夏至、处暑、白露节气呈极显著的升高趋势,年平均最低气温除大暑和处暑外呈极显著的升高趋势。20世纪70年代时谷雨节气的年平均最低气温变异系数最大,为0.41,80年代时小暑节气的年平均最高气温变异系数最小,为0.02。2010年以后,谷雨节气年平均最低气温的变异系数最大为0.21,夏至节气年平均气温的变异系数最小为0.02。

| Abstract: | Using the daily temperature data of Inner Mongolia autonomous region from 1971 to 2017,this paper analyzes the temperature changing characteristics of each solar terms in Tumed Left Banner by linear trend method,variation coefficient method and T test method.The results showthat the curve trends of daily maximum temperature,daily minimum temperature and daily average temperature are consistent,but the order has changed.The average daily temperature of grain rain,Xiaoman,summer solstice,slight heat,autumn,end of heat,and white dew show increased trend significantly.It indicates that the average daily temperature of the above solar terms is significantly increasing on the whole.The average daily maximum temperature of grain rain,summer solstice,slight heat,and white dew solar terms shows a very significant increased trend.And the average daily minimum temperature shows a very significant increased trend except the great heat and slight heat.In the 1970s,the annual mean minimum temperature variation coefficient of grain rain solar term was the largest,at 0.41;in the 1980s,the annual mean maximum temperature variation coefficient of minor heat solar term was the smallest,at 0.02.After 2010,the maximum coefficient of variation of annual mean minimum temperature of grain rain solar term was 0.21,and the minimum coefficient of variation of annual mean temperature of summer solstice solar term was 0.02. |
