- Abstract
The estimation of vegetation carbon storage and density of forests at tree layer in Tibet Autonomous Region was calculated based on the eighth forest inventory data using the biomass inventory method, as well as other attributes like tree trunk density and carbon content of different species. The results showed that the total carbon storage at tree layer in Tibet forest ecosystem was 1.067×109 t and the average carbon density was 72.49 t·hm-2. The carbon storage at tree layer of different stands was in the order of arbor forest > scattered wood > sparse forest > alluvial tree. The carbon storage of different forest types at tree layer were in the order of shelterbelt > special-purpose forest > timber forest > firewood forest. The proportion of the first-mentioned two was 88.5%, and the average carbon density of different forest types at tree layer was 88.09 t·hm-2. The carbon storage and its distribution area at tree layer in different forest groups were in the same order, followed by mature forest > over mature forest > near mature forest > middle aged forest > young forest. The carbon storage in mature forests accounted for 50% of the total carbon storage at tree layer in different forest groups. The carbon storage at tree layer in different forest groups increased first and then decreased with the increase of stand ages.
