今天人类活动引起的全球碳循环的扰动,已经掀起人们对全球碳循环的历史及其与气候和其它地球化学旋回的关系的新的兴趣。碳同位素地层学作为近两亿年来碳循环历史的监测器,已被证明是最有效的。在本文的引言里,总结了全球碳循环的运行模型,并证明了碳循环及碳同位素地球化学之间的联系。提出了阿普弟阶至阿尔布阶(Aptian-Albian)期间全球碳循环扰动的情况。在深海沉积的碳同位素地层研究中,记录了持续达数百万年的碳循环扰动。它叠加在高频沉积旋回之上,后者与持续时间为二万年、四万年和十万年的气候及海洋循环有关。本文论述的资料表明,全球碳系统的变化与地球化学循环的全球加速变化有关,后者是由大气中CO_2的长期变化引起的,而海底沉积的速率和火山活动则控制着大气中CO_2的变化。
The turmoil in the global carbon cycle caused by human activities today has given rise to new interest in the history of the global carbon cycle and its relationship to climatic and other geochemical cycles. Carbon isotope stratigraphy has proven to be the most effective as a monitor of the carbon cycle history of nearly 200 million years. In the introduction to this article, we summarize the operational models of the global carbon cycle and demonstrate the link between carbon cycling and carbon isotope geochemistry. The global carbon cycle perturbation during the Aptian-Albian period was proposed. In the deep-sea carbon isotope formation study, carbon cycle perturbations lasting millions of years were recorded. It is superimposed on high-frequency sedimentary cycles, which are related to the climate and ocean circulation that lasts 20,000, 40,000 and 100,000 years. The data discussed in this paper show that the changes in the global carbon system are related to the global accelerating changes of the geochemical cycles caused by long-term CO 2 changes in the atmosphere, while the rates of seabed sedimentation and volcanic activity control the changes of CO 2 in the atmosphere .
