The development and utilization of water source heat pump systems are closely related to the groundwater environment. In order to provide reference for the further development and utilization of water source heat pump projects in the research area,this article explores the influence of water source heat pump systems on groundwater environment from three aspects,including the groundwater dynamic field,the groundwater temperature field,and the groundwater chemical field. Among them,the groundwater level has been increasing year by year and the range of the falling funnel has been reduced. The water source heat pump system has no effect on the groundwater dynamic field in the study area;The groundwater temperature is generally stable,and there is a downward trend in the water temperature of the local geothermal single heating area. The temperature difference of the recharge water has a local impact on the groundwater temperature field in the study area;This system leads to strong evaporation of groundwater,increasing the content of Cl-and SO42-,and changing the hydro-chemical type from HCO3-Ca·Mg to HCO3·Cl·( SO4 )-Ca·Mg. The research shows that regular monitoring of groundwater indicators and reasonable setting of geothermal mining output can significantly reduce the adverse impact of water source heat pump system on groundwater environment,and promote the popularization and application of water source heat pump system and sustainable development.
