摘要
大气降水的同位素含量是国家的一项基本环境数据,也是开展环境同位素科学研究和环境同位素水文地质工作必不可少的基础资料。本文以我国17个地区的近两年多的实测长观资料为依据,参照全球大气降水同位素组成的赋存、分布规律,初步总结了全国大气降水稳定同位素背景值的基本分布特征和赋存、变化规律。得出了各地区雨水线和全国雨水线,讨论了影响降水同位素组成变化的相关因素。
The precipitation isotopic content is one kind of national basic environmental data, indispensable for the environmental isotope scientific research, including environmental isotope hydrogeology. Based on monitoring data of 17 areas of this country during the past two years and referring to the world precipitation isotopic pattern and distribution, this paper tentatively summarizes the basic distribution characteristics and the law of constitution and variation of the background values of the precipitation stable isotopes, obtains the r(?)gional and national meteorie water lines and discusses the correlating factors influencing the constitutional variations of the precipitation isotopes.
