摘要：

本文利用2005-2013年林业统计年鉴中每个省市新造林面积和遥感分类提取得到的2010年土地覆被类型,结合公开发表的各类森林生长方程和各个时期的森林存活率,估算了中国新造林在2005-2100年生物量碳库变化及其固碳潜力。结果表明：2005-2013年中国新造林面积达到4394×104 hm2,在自然生长状况下,到2020年新造林蓄积量增加16.8亿m3,生物量增加1.6 Pg,生物量碳库0.76 Pg C;新造林生物量碳库在2005-2100年中将增加2.11 Pg C,相当于目前现有森林生物量碳库的25%,约是过去20年森林总碳汇的1.5倍;新造林生物量碳密度逐年增加,最高达到48.1 Mg/hm2。整合林业统计年鉴以及遥感解译的森林类型对新造林生物量固碳潜力分析,研究表明新造林具有较大的碳汇潜力,对中国现有森林碳汇平衡有重要贡献。

Abstract:

Accurate estimation of the carbon sequestration potential of afforestation helps us better understand the carbon cycle in China and provides the guide for national forest policies. Forest data from China Forestry Statistical Yearbook were used to estimate carbon stocks and explore the carbon sequestration potential in China's forests in the next 100 years. In this study, we estimate the forest biomass carbon storage and carbon sequestration potential of new afforestation in China over the next 100 years based on new afforestation area from China Forestry Statistical Yearbook during 2005-2013 and forest type map in 2010 derived from remote sensing information. In the consideration of annual forest survival rate, carbon pools of the new afforestation are estimated with the forest growth equations for different forest types. The potential changes in China's forest biomass carbon storage between 2005 and 2100 were estimated with reconstructed forest areas. The results show that the total new afforestation area of China are 4394×104 hm2 from 2005 to 2013. With the assumption of continuous natural forest growth, the volume of new afforestation during 2005-2013 will increase to 16.8 billion m3. The biomass and carbon pool will increase to 1.6 Pg and 0.76 Pg C by 2020, respectively. The new afforestation biomass carbon storage will increase by 2.11 Pg C during 2005-2100. The carbon storage of new afforestation over the next 100 years are about 25% of current biomass carbon stocks in forests and are about 1.5 times of total forest carbon sink of the past 20 years. Furthermore, the biomass carbon density of China's afforestation will reach 48.1 Mg C/hm2 by 2100. In China, the new afforestation has played an important role in the increase of forest carbon storage and has a great potential for carbon sequestration. Therefore, forest management in China is of importance to mitigate increases in greenhouse gas emissions.
