摘　　要：依据华北地区500到3500米深地热井中地下水的化学组分和同位素组分,对华北地区地下热水D、18O、14C、分布特征进行了测定与分析,确定地下水的补给来源是古大气降水。运用放射性同位素14C测定年龄,分析华北地区热储层年龄是比较接近的,大致在15000—30000a范围。运用稳定同位素D计算补给高程,确定华北地区地热资源更新能力,属于弱可更新或不可更新的静消耗性开采,对今后地热资源的开发利用具有一定的参考价值。Geothemal waters were studied using hydro-geo-chemistry and isotopic properties to determine groundwater ages and identify the recharge sources in North China. The δ18O、δD andδ14C values of geothermal waters sampled from500 to 3500 meters deep. In order to understand the host environment of the geothermal water, The research on the isotopes of D、18O、14C in geothermal water in North China show that the characteristic distributing of environmental isotopic, it shows that old atmospheric precipitation is the recharge sources. Adioactive isotope 14C was applied to measuring the age of geothemal waters, heat reservoir age is relatively close, generally at the range of 15000-30000 meters, Calculation of recharge elevation using steady isotope D, the ability to renewable of Geothermal resources in North China, which belongs to weak renewable or unrenewable water, exploration belongs to the static consumption of mining, it has a certain reference value for the future development and utilization of geothermal resources.
