【摘要】 本文从海河流域平原区第四系中地下淡水同位素年龄和水文地球化学区域分布特征入手,对地下水形成年龄与其化学组分之间通过水循环演化过程而建立的关联机制进行了初步探讨,得出地下水¹⁴C校正年龄或其水文地球化学的区域分布特征中蕴涵着量化描述区域地下水循环演化进程和水动力学条件信息的新认识。更多还原

【Abstract】 This paper presents a preliminary research on the relationship between the formation age of groundwater and its chemical composition established through the evolution of groundwater circulation on the basis of the isotopic age of groundwater and its regional hydrogeochemical characteristics since the Quaternary in the Haihe River Plain. By this research this paper aims to reveal the evolution law of the regeneration ability and utilization of the groundwater resources, thereby providing a scientific basis for the evaluation of groundwater resources.更多还原
