Analysis of Biomass and Carbon Storage in Arboreal Forest of Qilianshan National Nature Reserve in Gansu Province
Based on the forest inventory data,the biomass,carbon density and carbon storage of arboreal forest in Qilianshan National Nature Reserve in Gansu Province were analyzed.The results showed that:(1)The average biomass and carbon density of arboreal forest were 127.67 Mg·hm-2 and 62.48 Mg C·hm-2;the total biomass and carbon storage were 2 3 36.53 × 104 Mg and 1 143.58 × 104 Mg C,respectively.(2)The biomass per unit area of Picea asperata and Sabina chinensis were 140.70 Mg·hm-2and 89.57 Mg·hm-2,seperatively;the carbon density was 68.94 Mg C·hm-2and 43.42 Mg C·hm-2;the forest carbon storage were 947.04 × 104 Mg C and 118.73 × 104 Mg C,accounting for 82.81％and 10.38％of the total forest carbon storage,respectively.The distribution area and carbon storage of other tree species groups was relatively narrow.The results of this study provide a basis and reference for evaluating the carbon cycle of forest ecosystem and reducing the uncertainty of regional carbon budget in Qilianshan.
