摘要
甘肃省北山地区是我国高放废物处置库场址重要预选区之一,花岗岩是处置库候选围岩。10余年来,在北山地区开展了水文地质和同位素水文学调查、研究工作,为场址评价提供了重要的水文地质依据。今后,在深入开展预选区水文地质研究工作中,应进一步开展同位素水文学研究,示踪地下水的补给来源,揭示水循环过程,测定地下水滞留时间和流速等,以获得高放废物处置场址特性评价所需的水文地质参数资料。
Beishan area in Gansu province is one of the pre-selected area of disposal repository for high level radioactive waste （HLW） in China. Granite is the host rock of the repository. Over the last decade, hydrogeological and isotopic hydrologic investigation and study were carried out in Beisha area. And pro- vided very important hydrgeological information and basis for the evaluation of the pre-selected site. For the future, more isotopic hydrologic study should be done to trace the recharge source of groundwater, to explore water circulation processes and to measure the age and velocity of groundwater circulation in the area. So as to obtain more useful hydrogeological data for the site evaluation of high level radioactive waste disposal repository.
