摘要
在野外采样的基础上,通过测试分析不同层位地下水中同位素2H、18O、3H的特征和水化学组成,利用同位素2H、18O和3H及水化学方法识别鲁北平原地下水的补给来源,估算黄河水与地下水的转化数量,揭示黄河下游平原区的水文循环特征。研究结果表明,鲁北平原浅层地下水的主要补给源为当地的大气降水和黄河水(包括引黄灌溉和黄河水渗漏),大气降水与黄河水所占的比例随距黄河的远近而变化。总补给量中,大气降水和黄河水的补给比例分别为86%和14%;深层地下水主要起源于古代大气降水,是在比现在寒冷的气候条件下大气降水入渗形成的。
Based on field investigation and by using isotope （D, ^18O and ^3H） and the water chemistry methods, this paper has identified the water source of groundwater for northern Shandong plain, estimated the supplying amount from Yellow River and revealed the hydrological cycling feature in the Yellow River downstream plain area. It is indicated that the major charging source of shallow ground water of northem Shandong plain is local precipitation and Yellow River water, and the proportion varies along as the distance away from the Yellow River. In total, precipitation accounts for 86%, and 14% for the Yellow River water. As to deep ground water, it＇s originated from ancient precipitation which seeps underground in a much colder chmate.
