陆地生态系统碳收支／碳平衡研究进展

Progress Studies on Carbon Budget/Carbon Cycle in Terrestrial Ecosystem

碳循环和全球变暖有着极其密切的关系,碳收支/碳平衡问题已经成为碳循环和全球变化研究的前沿与热点,其中陆地生态系统碳收支/碳平衡又是全球碳循环和影响全球变暖中最复杂、受人类活动影响最大的部分。阐述了全球陆地碳库的大小及碳收支/碳平衡状态,探讨了主要陆地生态系统碳收支/碳平衡过程,分析了当前影响陆地生态系统碳收支/碳平衡因素,并对当前陆地生态系统碳收支/碳平衡研究方向提出了自己的看法。

The carbon cycle had the extremely close relationship with global warming, studies in carbon budget and carbon balance increasingly became a focus of global change and carbon cycle, the terrestrial ecosystem, one of the most important parts of the global carbon cycle and global warming, was most complex and most greatly affected by human activities, This paper introduced the size of global terrestrial carbon pools and the state in carbon budget and carbon balance,discussed the process of main terrestrial ecosystem carbon budget/cathon cycle,and analyzed the current factors influencing the caron budget and carbon cycle,and lastly suggested the own views on current research directions of carbon budget and carbon balance in terrestrial ecosystem.
