In the article, the atmospheric and ground temperature changes in Hengshui City have been analyzed based on measured data of seven meteorological stations from 1959 to 2010. The research found that, during the 52 years in 1959-2010, the average air temperature of the city has significantly increased, and in the extreme weather, minimum temperature has greatly increased compared with the maximum temperature. During the 46 years in 1965-2010, the tendency of ground warming is very significant at the places of surface and below 20 cm rather than below 10 cm. In addition, the negligible changes of ground temperature were found in deep places of 40 and 80 cm far from surface. So the ground warming mainly origins from temperature increase of shallow soil 0 ~ 40 cm blow surface, which is also consistent with the change of air temperature. In contrast, the air temperature change is not consistent with the temperature variation of deep soil 80 cm below ground.
