摘要
利用阿鲁科尔沁旗气象站1960-2009年年平均气温数据,分析出近50年来阿鲁科尔沁旗的年平均气温增温趋势明显,达到了0.39℃/10a。采用滑动t检验、山本法和曼-肯德尔法3种突变检验方法对阿鲁科尔沁旗年平均气温进行检验分析,揭示了在50年时间尺度上,阿鲁科尔沁旗的气温存在明显的增暖突变,突变点在1987年。
Based on the annual mean temperature data of Arhorqin Banner Meteorology Burea from 1960 to 2009,the trend of temperature change was analyzed in recent 50 years.The test analysis were conducted on annual mean temperature of whole area with the three methods of Moving test technique,Yamamoto methods and Mann-Kendall methods.It showed that：on the timescale of 50 years, there was an obvious truth of warming and abrupt change on the temperature of Arhorqin Banner,abrupt change point was 1987.
