摘要
依据大兴安岭森林资源统计数据,对2000年和2013年大兴安岭森林的碳储量与碳汇量进行了估算。结果表明:2000年森林碳储量为22 875.88万t,2013年森林碳储量为24 928.66万t,2000—2013年大兴安岭森林碳汇量为2 052.78万t,年均增加碳汇157.91万t,年均增长率为0.69%,吸收CO2量为7 526.86万t;预测到2020年,大兴安岭森林碳储量将达到26 865.34万t,森林碳汇量1 936.68万t,年增长率1.11%,可吸收CO2量达7 101.16万t。
Based on the data of forest resource in Daxingan＇ling,carbon storage ＆ carbon sequestration in forest of Daxing＇anling Region in the year of 2000 ＆ 2013 were estimated. Result shows that： forest carbon reserves 228 758 800 t in the year Region of 2000, forest carbon reserves 249 286 600 t in 2013;forest carbon sinks are 20 527 800 t in Daxing＇anling Region from 2000 to 2013 ;carbon sinks increase 1 579 100 t annually;the mean annu al growth rate is 0.69% ;the absorption amount for CO2 are 75 268 600 t;it is forecasted that the carbon stocks carbon sinks of forest in Daxing＇anling will reach 268 653 400 t ＆ 19 366 800 t, respectively in 2020 ;annual growth rate is 1.11% ;the absorption amount for CO2 are 71 011 600 t.
