全球变化研究热点——碳循环

40多年来,全世界的科研工作者已经在碳循环领域的各个方面做了大量的工作.本文总结了全球碳循环研究的最新进展,着重介绍了大气CO2浓度的变化及增长趋势,陆地生态系统和海洋对于大气CO2浓度变化及由此而引起的气候变化的反馈及其研究现状.同时,对许多固碳措施和技术方法也作了阐述.目前全球碳循环研究已经达到了系统集成的高度,因此集成研究将是21世纪碳循环研究的发展趋势.

A focus topic of global change study: carbon cycle.

Much work has been done in the field of global carbon cycle for about forty years. The latest progress in the study on the terrestrial and oceanic feedback to the continuous increase of atmospheric carbon dioxide concentration and the change of climate is introduced in detail. Many ways of carbon fixation are also discussed in the article, which may mitigate the negative effects of human activities. In addition, the future trend of global carbon cycle study is also addressed in this paper. Since the earth has been seen as a system, synthesis studies of carbon cycle have been made and will be developed further in the new century.
