未来中国森林碳蓄积预估初步研究

根据我国林业部分的规划,在持续、有序绿化的前提下,从2005~2044年,中国森林从大气中净吸收的C可达到51.74×108~125.30×108t,约占同期我国CO2排放总量的27.1%~65.6%。年吸收量呈逐年递增态势,2025~2044年间的年平均吸收量可达1.91×108t。在实现国土绿化的过程中,我国森林资源将强烈抑制大气CO2的升高,具有极其可观的生态效益、环境效益。我国森林资源CO2同化能力和碳蓄积量的双双提高,将为我国的经济发展预留更广阔的CO2排放空间,对我国参与国际间环境以碳排放的谈判具有实质性意义。

The Research of Carbon's Storage Capacity of China Forest Systems in the Future

According to China's ecology and environment situation,this article estimates with future development of china forest systems and carbon cycle status of the globe.It is thought that carbon sink function of china's forest systems is remarkable,and steady territory afforest policy and forestry development strategy will further strengthen carbon sink function of china's forest systems.Having been proposed and been proved the thinking of forest development of China about "20 years + 20 years".According to the plan of "20 years + 20 years",in the 40 years from 2004 to 2043,the net absorption of carbon of china forest will reach(51.74×10~8t) and the amount of annual net carbon absorption will increase year by year.In the second 20 years,the average amount of annual carbon absorption will be not lower than 1.91×10~8 tamount up more than 23.7% of total amount of china carbon discharge of 1996.
