| 摘 要： | 环境同位素研究结果表明,研究区地热水为大气降水成因。根据降水补给的年代及混合程度可将地下热水分为主要由现代大气降水补给的混合型地下热水;由现代大气降水和古代降水补给的混合型地下热水;主要由古代大气降水补给的深部循环型地下热水。

| Abstract: | The meteoric origin of geothermal water in study area is evidenced by its environmental isotope composition.The geothermal water can be classified into three categories based on the time when replenishment take place and mixing extent with normal groundwater which are: geothermal water mixing with normal groundwater recharged mainly by the modern meteoric water;geothermal water mixing with normal groundwater water recharged by both ancient and modern meteoric water;deep-runoff geothermal water recharged mainly by ancient meteoric water. |

| Keywords: | geothermal water environmental isotope precipitation Guanzhong Area |
