根据德州2006—2007年自动站和人工站地温平行观测数据,分析地面、5～320cm层地温对比差值的日、月变化规律及原因。结果表明：0～15cm层差值日变化随着温度升高而增大,即白天差异较大,夜间差异较小。地面0cm、地面最高、地面最低温度的人工观测值偏低,月平均差值均为负值。其中地面最高温度差值变化幅度最大,标准差为0.62℃;其次是地面最低温度,标准差为0.23℃;地面0cm层差值变化幅度最小,标准差为0.15℃。15～20cm层月平均差值为正值;5～10cm、40～320cm层月平均差值为负值,并且差值变化幅度随土壤深度加深而变小。分析结果表明：季节和温度的变化是导致地温差值大小的主要原因。

Based on Dezhou ground temperature data observed by automatic station and manual station during the year of 2006-2007, daily and monthly variation rules and reason analysis for differences of 5~320 cm ground temperature are analyzed. The results show that daily variation of 0 cm~15 cm ground temperature increases with the temperature, that is quite different during the day and little at night. The temperature observed by the manual is relatively low at the position of ground 0cm, maximum and minimum point, and monthly average differences are negative. And the change range of ground maximum temperature is the highest, and standard deviation is 0.62. Standard deviation of ground minimum temperature is 0.23. Standard deviation of ground 0cm is 0.15 with minimum change range. Monthly average differences of 15~20 cm are positive, while 5~10 cm and 40~320 cm are negative. The difference variation is changed with soil depth, that is the deeper the soil, the smaller is the difference. The main reason caused ground temperature differences is seasonal changes in temperature.
