Estimation of Forest Vegetation Net Production,Carbon Storage and Carbon Sink Function in Qilian Mountains
摘要
Abstract
The forest vegetation biomass,carbon storage,increment,litter amount,net production and carbon sink function were studied by volume-derived biomass method in Qilian Mountains.The results showed that the total biomass of 11 forest vegetations,total carbon storage,total growth increment,and annual litter amount,and net production were 4.06× 107 t,1.90× 107 t,1.49× 106 t · a-1,9.3 × 105 t · a-1,and 2.4 × 106 t · a-1,respectively.Stands of the tree species with higher biomass were Picea crassifolia and Sabina przewalskii forests,smaller ones were Pinus tabulaeformis and Larix principis-rupprechtii forests,and the medium ones were mainly distributed in middle-aged and near-mature forests.The average carbon density was 201.07 t ·hm-2,for individual stands,the density followed the order of Betula platyphylla>mixed coniferous and broad-leaf > B.albo-sinensis > P.tabulae forrnis > Populus davidiana > coniferous mixed> Populus spp.>mixed broad-leaf> Sabina przewalskii > Picea crassifolia > L.princi pis-rupprechtii forests.The total increment,annual litter amount and net production were higher in Populus davidiana and S.przewalskii forests,lower in P.tabulaeformis and L.principis-rupprechtii forests,and in the age group distribution,the order was middle-aged> near-mature> mature> young> over-mature forests.The potential price for carbon trading was $1.11 × 109 (JI)or $1.68× 109 (CDM)and the potential price for carbon trading of P.crassifolia forest was $ 7.01 × 108 (JI)or $1.06 × 109 (CDM),62.98% of the total potential price of carbon trading.关键词
