摘要
Based on samples of the groundwater,using isotope technology and combining hydrogeological condition analysis,this paper focuses on the groundwater circulation rule on Beijing plain area.In the paper,the groundwater age is calculated by using the dating techniques of 14C and 3H,and the groundwater source is analyzed by analyzing groundwater relation curves of D and 18O.According to whether actively participated in the modern water circulation,the Quaternary aquifers in Beijing plain area are divided to shallow aquifer and deep aquifer,then the recovery situation of shallow and deep aquifers are studied. The result shows that the shallow water widely distributes in Beijing plain area,its runoff condition and recovery are relatively good. The deep water mainly distributes in bottom of alluvial-pluvial fans for the Yongding River and the Chaobai River, the recharge conditions are relatively poor,with the little interconnection with modern atmospheric rainfall.
