Abstract: The groundwater source heat pump system,one of the main ways of shallow geothermal resources development,is being widely used in China these years.This paper took a groundwater source heat pump project in Zhengzhou City as a case,and studied the impact of shallow geothermal resources development on groundwater environment through numerical modeling of HST3D.The results showed that the groundwater temperature had risen slightly after the project had run for eight years.It had risen by 0.5 Celsius degree and 0.2 Celsius degree respectively in the pumping well No.3,which is relatively near to the injection wells,and in the pumping well No.6,which is relatively far to the injection wells.The simulation results were basically consistent with the observed data.
