工业革命以来,人类活动向大气排放了大量矿物燃烧CO_2。由于大气CO_2的增加而可能引起的全球变暖问题及其对环境和生态的影响已经引起了科学家和政策制定者的注意。海洋、陆地生物群都在与大气进行CO_2交换,那么,过量CO_2将如何在它们的容器——大气、海洋和生物圈——中分配呢?也就是,碳是如何及将如何在全球循环呢?在大量实际观测基础上,海洋化学家、地球化学家及气象学家进行了大量的计算和模拟,试图回答这些问题。纵观有关碳循环方面的文献,由Broecker、Craig等人建立起来的箱式模型发展较快,应用较广,在处理CO_2问题上已初见成效。
Since the Industrial Revolution, anthropogenic activities have emitted large quantities of CO 2 into the atmosphere. The global warming problems that may arise due to the increase of atmospheric CO 2 and their environmental and ecological impacts have drawn the attention of scientists and policy makers. How are the excess carbon dioxide distributed in their containers - the atmosphere, the oceans and the biosphere - that is, how and how carbon will circulate around the globe? Based on a large number of actual observations, marine chemists, geochemists and meteorologists carried out extensive calculations and simulations in an attempt to answer these questions. Throughout the literature on carbon cycling, the box model developed by Broecker and Craig et al. Develops rapidly and has a wide range of applications and has achieved initial success in handling CO_2.
