Abstract: In order to study the impact of climate warming on shallow geotemperature in Tianshui, based on data of annual and monthly ground temperature in 0 cm to 20 cm in Tianshui from 1963 to 2012, the author analyzed the variation characteristics of ground temperature and its response to climate changing with the method of climate tendency rate, variable coefficient, nine points twice matching, Mann-Kendall test and the signal-to-noise ratio. The result showed that: annual and seasonal shallow geotemperature turned out increasing trend. The range of increasing of annual ground temperature was 0.02℃ to 0.47℃ per 10 years and that of seasonal was 0.17℃ to 0.47. ℃ per 10 years. It also showed that the annual variation coefficient of shallow geotemperature was the biggest in the winter and the smallest in the summer. The ground temperature variation in a decade of century also showed increasing trend. It experienced the evolution of cold to warm in all variation process, that showed it was colder period in 1960s to 1990s, warm period in 1990s to 2010s, and became colder again after 2010s. The turning point of ground temperature was around 1993 and was more obvious in depth of 5 cm and 20 cm.
