摘　　要：文章主要阐述了瑞典Forsmark和Laxemar两处高放废物处置库候选场址地下水化学的垂向分布特点、地下水化学形成过程,以及用于场址安全评价的水文地球化学指标。混合作用是Forsmark和Laxemar场址地下水形成演化最主要的作用,主要由深部古盐水、冰川融水、古海水和现代大气降水入渗水混合而成。用于安全评价的部分地下水水文地球化学指标主要包括:TDS值、 Eh值、 pH值、 Ca+Mg、 DOC及胶体等。上述研究为我国高放废物处置水文地球化学的研究提供参考和借鉴作用。This paper mainly describes the vertical distribution of groundwater in two candidate sites of Forsmark and Laxemar, the formation of groundwater, and the hydrogeochemical index for sites safety assessment. The mixing effect is the most important role of groundwater formation and evolution in the Forsmark and Laxemar sites. It is mainly composed of deep saline groundwater, glacial melt water,Littorina sea water and modern Meteoric water. And the hydrogeochemical index for sites safety assessment mainly includes: TDS, Eh, pH, Ca+Mg, DOC and colloid. The researches in Sweden provide reference for the high level radioactive waste disposal in China.
