摘　　要：利用3 H法和CFCs法对河南平原第四系浅层地下水年龄进行计算,为河南平原浅层地下水可更新能力评价和水循环的研究提供依据。结果表明:2种方法计算出的年龄拟合误差较小(2a),均可代表河南平原浅层地下水年龄。总体上,河南平原浅层地下水主要为近50a以来补给的现代水。太行山、伏牛山、大别山山前地区以及开封西部的黄河两岸等地区浅层地下水年龄均小于30a,并且顺着地下水流向年龄逐渐增大。从山前地区和黄河两岸至平原区,浅层地下水开采潜力逐渐减小。总体上:平原北部地下水系统地下水年龄较小,地下水循环交替较快;平原南部地下水系统次之;平原中部地下水系统地下水年龄最大,地下水循环交替最慢。The 3H method and CFCs method were applied to date the Quaternary shallow groundwater in order to study the groundwater cycle and renewability evaluation of shallow groundwater in Henan Plain.It can be concluded that the fitting error was small（2 a） so that the ages calculation by the two methods can represent the shallow groundwater ages in Henan Plain.In general,the shallow groundwater was the modern recharged water which was younger than 50 a.The groundwater age was younger than 30 a in the piedmonts of Taihang Mountain,Funiu Mountain,Dabie Mountain and along two sides of the Yellow River on west of Kaifeng.The age increased along with the groundwater flow path.The exploration potential decreased from the piedmonts and the two sides of the Yellow River to the plain.In general,the groundwater cycle was faster in the northern groundwater system of which age was younger,followed by that in the southern groundwater system.The groundwater cycle was the slowest in central groundwater system of which age was the oldest.
