摘　　要：【目的】利用河北省20个气象观测站的逐月0 cm地温,对河北省0 cm地温变化特征进行研究。【方法】采用数学统计法,利用一元线性回归分析等方法进行河北省0 cm地温变化特征分析。【结果】1960—2020年河北省年平均地温呈显著波动上升的趋势,地温倾向率为0.36℃·(10 a)-1(P<0.01),与我国其他地区地温时间变化特征相似。【结论】河北省年均地温升高主要受春季、冬季和秋季的季节影响。春季为四个季节中平均地温变化相差最大的季节。[Purposes]Using the monthly 0cm ground temperature of 20 meteorological observation sta⁃tions in Hebei Province,the characteristics of 0cm ground temperature variation in Hebei Province were studied.[Methods]In this paper,the characteristics of 0cm ground temperature change in Hebei Prov⁃ince were analyzed by using the method of mathematical statistics and unitary linear regression analysis.[Findings]During 1960—2020,the annual mean ground temperature in Hebei Province showed a sig⁃nificant trend of fluctuation and increase,and the ground temperature tendency rate was 0.36℃·(10a)-1(P<0.01),which was similar to the time variation characteristics of other regions in China.[Conclusions]The annual average ground temperature increase in Hebei Province was mainly influeced by the seasons of spring,winter and autumn.Spring is the season with the biggest difference in average ground tempera⁃ture among the four seasons.
