摘　　要：地下水在下渗过程中,受地温梯度的影响,水温度会逐渐升高,从而相同压力下的密度就会降低。这种由于温度不同所导致的密度差异会引起地下水的运动,将该种机制称之为地下水运动的热驱动机理。基于此种机理,给出地形变化较小的丘陵地区地热水近源补给的模型,解释同一或相近海拔高度上补给区与排泄区(地热水温泉)共存的现象,提出并论证在地势低洼地带得到补给、而在地势较高处出露温泉的可能性。Because of geothermal gradient, the temperature of groundwater increases gradually when groundwater infiltrate deeper and deeper and the density of goundwater decreases afterwards. The phenomenon that the variation of density leads to groundwater movement called thermally driven. On basis of thermally driven, the paper establishes an model of thermal water resouces recharge in flatter hilly regions and tries to explain the co - existence of spring recharge area and spring discharge area in similar sea level. Then, the paper demonstrates the possibility of thermal spring in high level while recharging in low level.
