| 摘 要： | 大气降水作为地下水的主要补给源之一,它是自然界水循环过程中的一个重要环节.查明大气降水中同位素分布特征及其影响因素,不仅有助于定性或定量地研究地下水的起源和形成等问题,更有助于揭示"三水"转化关系.根据全球大气降水同位素观测网 1985～1993 年大气降水氢氧同位素资料并结合所采集样品的分析结果对陕西关中盆地大气降水环境同位素特征、变化规律及其影响因素进行了探讨,建立了西安地区雨水线,为地下水的起源及运移研究奠定了基础.

| Abstract: | The meteoric water is one of the main recharges for groundwater.It is an important part in the circulation of nature water.Ascertaining the distribution characteristics and influenced factors of some isotopes in meteoric water is not only helpful to research the sources and form of groundwater qualitatively and quantitatively,but also reveal the change relationships of the rain water, the surface water and the groundwater.On the basis of some isotope data of meteoric water from 1985 to 1993 on the IAEA net and analysis data of samples,the paper discusses the characteristics,changes regularities and some influenced factors of environmental isotopes of meteoric water in Guanzhong Basin,and also establishes the Local Water Line in Xi'an.All studies have established the basis of researching the resources and movement of groundwater. |
