Abstract
Based on the daily temperature of Zhangjiakou City from 1960 to 2011 ,the characteristics of accumulated temperature change of ~〉0 ~C was analyzed by using the methods of linear trend estimates. The results indicated that ：The annual temperature showed an increasing trend with the linear warming rate of 0.42 ℃/10 a during the past 52 years. After 1983 ,the warning trend increased significantly. ≥0 ℃ accumulated temperature showed an increasing trend with the warming rate of 89.4 ℃/10 a. The trend of initial date of ≥0 ℃ appeared ahead ,while the terminal date was delayed ,so the sustained days of the boundary temperature increased significantly. In the past 52 years ,the delay of the terminal date of the boundary temperature was greater than the ahead of the initial date.关键词
