| 摘 要： | 将环境示踪技术用于地下水定年以确定地下水的相关时间尺度问题在过去几十年中得到了长足发展,尤其是在年轻地下水定年方面。目前国内外用到的年轻地下水环境示踪剂有多种,这些示踪剂在地下水定年方面各有利弊。本文的目的是对国内外现有的9种年轻地下水示踪剂(3 H、3 H/3 He、4 He、35S、36 Cl/Cl、85 Kr、222 Rn、CFCs和SF6)的来源、示踪原理、误差来源、优缺点、适用性和应用现状等进行归纳和总结,为研究者、管理者和决策者在应用时提供参考。

| Abstract: | It has been experienced a fast development over the past decades using environmental tracing techniques dating groundwater and further determining the timescales of groundwater, especially dating young groundwater. There are many young groundwater tracers used both at home and abroad now; all of which have distinct advantages and disadvantages. The objective of this paper is to conclude and summarize the characteristics of these nine young groundwater tracers around the world (3H, 3H/3He, 4He, 35S, 36Cl/Cl, 85Kr, 222Rn, CFCs and SF6), including their sources, tracing theories, sources of errors, advantages and disadvantages, applicabilities, and application statuses, which can give references to researchers, managers and policy-makers. |
