中文摘要：

在野外采样的基础上,通过测试分析温泉及地热井中地热水的同位素2 H、18 O、3 H的特征,利用同位素地球化学方法识别鲁东地热区地下热水的补给来源。结合高程效应确定补给范围为地形较高的丘陵地带。根据3 H的测试数据应用法国J.FT.（丰特）来特的经验估算结果和构建δ18 O与纬度之间的关系对鲁东地热水的补给来源进行判别,得出鲁东地热区地热水补给来源为现代大气降水。

英文摘要：

This paper analyzes the features of hydrogen and oxygen isotopes 2 H,18 O and 3 H in geothermal water from hot spring and geothermal well based on sampling and testing.The study identifies the makeup source of geothermal water in east Shandong Province by isotope geochemistry method.Combining the elevation effect,the paper selects the area with relatively high hills as the area to be made-up.In addition,the paper uses 3 H testing data and the result of J.FT.experience-based estimation and constructs the relation betweenδ18 O and latitude to determine the make-up source for geothermal water in east Shandong Province-meteoric water.The results show that the make-up of geothermal water is the rainfall.
