摘　　要：对台兰河流域地下水库库区的地表水、地下水进行取样,检测了水样中R11、R12、R113的浓度,计算了地下水年龄及混合比例。结果表明:台兰河流域地表水的平均年龄在1989-1991年之间,这是由于多年前的冰川储水融化,使地表水年龄较现状年降水偏老;台兰河流域地下水的年龄在1956-1985年之间,由南向北年龄越来越老,其中新水占21%～58%。根据地下水年龄和比例,粗略计算了地下水径流速度和更新速率:312国道南侧至阿库木闸处地下水径流速度为300m/a,山前至阿库木闸的地下水径流速度为727m/a,地下水每年更新速率为0.32%～0.89%之间。The water in Tailanhe Basin are sampled and the concentration of Rn ,R12 ,Rm in them are determined. The samples＇ages and mix proportion are calculated. The average age of the surface water in Tailanhe Basin was between 1982 and 1990. The glacier kept a large amount of precipitation several decades ago. It made the average year of the groundwater older when it was melt into water and recharged to the underground. The average age of the groundwater in Tailanhe Basin was between 1956 and 1990. The age of the groundwater in the South of the research area were older than in the North. 30%- 50% of the groundwater data before 1945s. The velocity of flow and renewal rate of the groundwater are calculated according to their age and percentage. The velocity of flow of the groundwater located between the south of 312 national highways and Akumuzha was 300m/a and 727m/a between moun rain to Akumuzha. The renewal rate of groundwater is 0. 55%/a.
