摘　　要：用天然水溶液中２３４Ｕ与２３８Ｕ之间的放射性不平衡研究的方法，对鲁南两城地区３０组水样地表水和地下水铀同位素组分进行了实测。结果表明，本区地下水有三个来源：深部喀斯特岩溶水、浅部孔隙水和地表水。水的铀同位素组分稳定，并应用混合比例计算了地下水资源量，其结果与常规方法计算结果完全一致。Determination of uranium isotope contents has been made by the method of radioactive disequilibrium between 234U and 238U for the surface and underground water from Liangcheng region of southern Shandong Province, and the results of 30 water samples analyses are presented.These results show that the underground water has three sources, namely deep karst, shallow porous and surface waters. The uranium isotopic compositions of water are quite stable, and the mixing ratio of water body has been used to evaluate the amount of water resource in considered area.The results of calculation is of the same with those obtained by other regular method.
