利用内蒙古通辽市库伦旗气象站53年(1961-2013年)初、终霜出现的日期及无霜期序列资料,采用平均值、一元线性回归、曼-肯德尔(Mann-Kendall)等方法对它们的变化趋势及分布等特征进行分析.结果表明:库伦旗的无霜期的初日不断提前,终日不断推后,无霜持续日数不断增加,其倾向率为每10年增加4.7 d.

By analyzing the beginning, the last frost d ate and frostless period sequence of Kulun meteorological stations in Tongliao of 53 years (1961-2013), we explored their variation trends and distribution characteristics using mean, monadic linear regression and Mann-Kendall methods. The results showed that the frostless period of Kulun in the early days advanced constantly; the final days postponed ceaselessly; the days of frostless duration increased continually;the tendency rate of it was 4.7 d/10a.
