摘要
依据大兴安岭森林资源数据,利用林业行业标准《森林生态系统服务功能评估规范》(LY/T 1721-2008)中相应方法,对大兴安岭森林的固碳释氧生态服务功能实物量及价值量进行了评估。结果表明:大兴安岭森林植被固碳量为3 277.59×10~4 t·a^(-1),单位面积固碳量为4.828t·hm^(-2)·a^(-1);森林植被释氧量为8 774.63×10~4 t·a^(-1),单位面积释氧量为12.924t·hm^(-2)·a^(-1);大兴安岭森林植被固碳释氧总价值为1 270.77亿元·a^(-1)。
Based on the data of forest resources in Daxing'anling Mountains and using the corresponding method in the"Forest Ecosystem Services Evaluation Norms"(LY/T 1721-2008),the physical and carbon content of carbon sequestration and oxygen release ecosystem services in the forest of Daxing'anling Mountains were evaluated.Result shows that the carbon sequestration of forest vegetation in Daxing'anling is 3 277.59 × 10~4 t·a^(-1),and the carbon sequestration per unit area is 4.828 t·hm^(-2).a^(-1);the oxygen release rate of forest vegetation is 8 774.63 × 10~4 t·a^(-1),and the oxygen release per unit area is 12.924 t·hm^(-2)·a^(-1);the total value of carbon fixation and oxygen release from forest vegetation in Daxing'anling Mountains is 127 077 million Yuan·a^(-1).
