摘　　要：通过研究井温曲线类型,确定研究区纯传导地温梯度为2 5℃100m;结合各单井地温梯度,圈定了地热异常区域;揭示了该区地热异常具有下段以对流为主、上段以传导为主的特点。通过热水水化学和同位素数据的综合分析表明,该区地下热水补给来源为大气降水,热水赋存于断裂裂隙系统中,且沿断裂裂隙垂向运动十分强烈。Based on the regional geological setting and hydrogeological conditions, the geothermal gradient has been determined of 2.5℃ per 100m rising downwards in this area by way of well logging temperature curves. The geothermal anomaly from a group of single-well temperature gradient can be characterized in the study area in which the superiority of convection occurs in the lower segment and the geothermal conductivity in the upper segment. The analysis of hydrochemistry and isotopes shows the fact that geothermal resource occurs in the fractures along the fault zone where the recharge to the geothermal water is derived from precipitation and along which the vertical movement of geothermal water is rather intense.
