放射性碳同位素(14C)可以有效的用于地下水年龄测定,并作为示踪剂求取水文地质参数,研究地下水动态,已为水文地质的发展作出了巨大的贡献。尤其是近十年来,14C制取测试技术和数据分析理论的迅速发展给水文地质的研究带来了新的动力。本文具体介绍了14C在水文地质上测年和示踪剂的应用进展,并概述了推动其发展的测试技术分析理论,最后对今后的研究方向提出了展望。
The radioactive carbon isotope (14C) can be effectively used for the determination of groundwater age, and as a tracer to obtain hydrogeological parameters, groundwater dynamics study has made a great contribution to the development of hydrogeology. Especially in the last ten years, the rapid development of 14C preparation test technology and data analysis theory has brought new impetus to the research of hydrogeology. In this paper, the progress of 14C hydrogeology dating and tracer application is introduced in detail, and the theory of testing technique that promotes its development is outlined. Finally, the future research direction is put forward.
