| 摘 要： | 研究海洋中的氟氯烃对全球气候变化和海洋环流的研究有重要意义.氟氯烃不仅是温室气体,还破坏大气平流层中的臭氧,也是近代海洋科学研究的有效工具,可以作为化学示踪剂,广泛用于示踪海洋环流、水团运动混合过程、海洋通风过程,测定水团年龄、海水混合和循环速率以及海气交换速率等的研究.对过去几十年海洋中氟氯烃的研究进展进行了评述,介绍了海水中氟氯烃的分布特征与通量研究、氟氯烃在海洋中的应用及分析方法,同时简述了大气中氟氯烃的分布特征.概述了该研究领域有待进一步研究的问题.

| Abstract: | Oceanic Chlorofluorocarbons (CFCs) are very significant in climate change and ocean’s circulation study. CFCs have greenhouse effect and are useful tools for modern marine research. CFCs, as chemical tracers, have been widely used to assess ocean circulation and marine ventilation pathways, and to identify the mixing processes of water mass movement. CFCs are often used to calculate the “age” of water masses and rates of ocean mixing and circulation, and to evaluate air sea exchange rate. The progressess of studies of oceanic CFCs in the past several decades are reviewed in this paper. The distribution characteristics and flux of CFCs in the ocean, and their application to marine research and analytical methods are introduced. Their distribution characteristics in the atmosphere are also described. Some questions for further research in this area are proposed. |
