英文摘要： As the new type of the exploitation of the shallow low-temperature geothermal energy, it has the important application background in energy-saving, carbon-emission reduction, and utilization of the renewable energy for the Groundwater Source Heat Pump (GWHP) system. The crucial scientific issues about the thermal transport process mechanism in saturated media should be discussed, such as the thermal interference of groundwater temperature field, the arrangement of the pumping and injecting wells, the running effect of the GWHP system and the evolution of the regional geothermal field. The research methods such as the physical model experiments, the numerical simulation and the control analysis of system theory will be adopted in this study from the point of view of regional geological environment system.The targeted experimental device system will be designed and developed to simulate the thermal transport process characteristics in saturated media under special groundwater-flow and heat source condition of thermal source/sink terms for the GWHP system physically. The mathematical and numerical model will be established and verified to simulate the influence of the characteristic factors change of medium structure on the thermal transport process in saturated media. The geo-environmental thermal response of the
