摘要: 根据2003年西辽河平原(内蒙古部分)地下水、河水及雨水的同位素测试结果,分析了该地区地下水的同位素分布特征及地下水的补排关系;利用浅层地下水3H浓度计算出不同流域的地下水平均年龄,同时利用14C数据计算出承压水的14C年龄及其区域流速.Abstract: Based on the isotopic testing result of the groundwater, river water and rain water from the Western Liaohe plain (of Inner Mongolia part) in 2003, the distribution characteristics of isotopes and the recharge-drain relations of groundwater in the region are analyzed. The average ages of groundwater from different river basins are calculated by the concentration of 3H in the shallow groundwater. The 14C ages and the regional velocities of the confined water are also calculated according to 14C data.
