Assessment of Carbon Density in Natural Mountain Forest Ecosystems at Northwest China.

ABSTRACT: The natural mountain forests in northwest China are recognized as a substantial carbon pool and play an important role in local fragile ecosystems. This study used inventory data and detailed field measurements covering different forest age groups (young, middle-aged, near-mature, mature, old-growth forest), structure of forest (tree, herb, litter and soil layer) and trees (leaves, branches, trunks and root) to estimate biomass, carbon content ratio, carbon density and carbon storage in Altai forest ecosystems. The results showed that the average biomass of the Altai Mountains forest ecosystems was 126.67 t·hm-2, and the descending order of the value was tree layer (120.84 t·hm-2) > herb layer (4.22 t·hm-2) > litter layer (1.61 t·hm-2). Among the tree parts, trunks, roots, leaves and branc
