Abstract: The climate tendency rate method was used to analyze the tendency of the shallow geothermal changes of Dabancheng. The results showed that the shallow ground temperature increased gradually. The ground temperature of 0 cm has the largest climate tendency rate of 0.779˚C/10a, which decreases from shallow to deep in turn. 5 cm, 10 cm, 15 cm, 20 cm ground temperature climate tendency rate is 0.648˚C/10a, 0.630˚C/10a, 0.564˚C/10a, 0.527˚C/10a respec- tively. The warming trend of each layer is most obvious in summer with the tendency rate reaching 0.807˚C/10a, which is followed by spring and autumn with the rate of 0.770˚C/10a and 0.687˚C/10a respectively. Mutation analysis showed that the shallow ground temperature was mutated to increase in 1997. Partial correlation analysis method was used to analyze the reason why the ground temperature of Dabancheng increased. The results showed that average tempera- ture and sunshine durati
