大气圈碳循环的模拟研究进展

碳元素是地球生命的重要组成元素，而大气中的ＣＯ２是生命物质中碳元素的最主要来源，它也是引起气候长期变化的外强迫作用中最主要的温室气体，观测资料表明，在工业革命后，由于人类工农业活动的影响，大气圈中ＣＯ２含量增加很快。了解碳的源汇分布，大气圈碳循环动力机制以及碳循环与气候系统的相互作用，并进一步了解碳循环在整个地球系统内的作用过程十分重要。本文综合了近年来一关于碳循环在整个地球系统内的作用过程十分重

ON THE SIMULATION STUDIES OF CARBON CYCLE IN THE ATMOSPHERE

Carbon is an important element of lives on the earth.The main source of carbon in the creature is carbon dioxide in the atmosphere.Also it is the most important greenhouse gas that influences the long-term climate change.After industry revolution,observations indicate a sharp increase of global carbon dioxide that mainly results from human activities.Studies of carbon cycle will help us with a deeper understanding of the interaction between carbon cycle and climate systems.In present work we give an introductory survey of the simulation of carbon cycle in the atmosphere .The statistics and modeling were widely used in the studies of carbon cycle in the atmosphere.Each research tool has its merits.Modeling,especially 3-D coupling general circulation model (GCM) can describe the dynamic processes of carbon cycle in the atmosphere in detail.However,the statistics method needs less calculation costs.
