Result After the ground-source heat pump system ran continuously for a period of time, the temperature field in the range with the semidiameter of 0.8 m around the underground pipeline showed intensive changes. The changes of the temperature field in the area outside this region became smaller till it was close to the original temperature of soil. The original temperature field in the soil of shallow ground surface showed an exponential correlation with the depth. When the depth reached to certain extent, the soil basically maintained the constant-temperature state and it was 1~2 ℃ higher than the annual average temperature.
