    Groundwater is the premise of water source heat pump application, groundwater temperature directly influences the working efficiency of heat pump unit and the sustainable use of engineering, therefore, it has very important practical value to research on the changes of groundwater temperature, which can provide a reliable basis for the engineering design and appli-cation. Improved grey model GM ( 1 , 1 ) is applied to the prediction of groundwater temperature in Baoji city is feasible, sim-ulated and measured values fit good, the model reveals nicely that the groundwater temperature increased with increasing depth.
