温室效应和臭氧层破坏、酸性沉降物并列为世界三大环境难题,其研究的中心内容是CO2问题。占地球面积71％的海洋对大气中CO2的迁移、转化贮存起着重要作用。中国全球海洋通量联合研究委员会(C-JGOFS)已经成立,而这其中的化学海洋学占据极其重要的地位,本文对全球海洋通量联合研究中的化学海洋学问题进行了探讨。 Greenhouse effect and ozone layer destruction, acid sedimentation are listed as the world’s three major environmental problems, the focus of its research is the issue of CO2. The oceans account for 71% of the earth’s surface and play an important role in the transfer and storage of CO2 in the atmosphere. C-JGOFS has been set up and the chemical oceanography plays a very important role in this field. This paper discusses the issue of chemical oceanography in the joint global ocean flux study.
