Based on the daily ground temperature, air temperature, wind speed, solar duration, and total cloud cover observation data of 5 stations in Shijiazhuang from 1961 to 2010， the characteristics of the maximum and minimum ground temperature，as well as the relationship of air temperature， precipitation，wind speed，solar duration，and total cloud cover to ground temperature, are analyzed. The results show that the diurnal amplitudes of the maximums were bigger, obviously in winter; those of the minimums were smaller, obviously in summer. The maximums had a clear cooling trend in summer and autumn， the minimums had a clear warming trend in various seasons. There was a positive correlation between maximum ground temperature and maximum air temperature，solar duration，and wind speed，while a negative correlation between maximum ground temperature and total cloud cover. There was a positive correlation between minimum ground temperature and minimum air temperature， total cloud cover， while a negative correlation between minimum ground temperature and wind speed， solar duration. The maximum air temperature had a maximal positive effect on the maximum ground temperature， while wind speed had a minimal positive effect. The total cloud cover had a negative effect on the maximum ground temperature and was stronger in summer and winter. The minimum air temperature had the strongest positive effect on the minimum ground temperature， while total cloud cover had the weakest positive effect. The wind speed had a negative effect on the minimum ground temperature and was stronger in spring and autumn， while solar duration was stronger in autumn and winter.
