摘      要：The raising concentration of atmospheric CO_2 resulted in global *** forest ecosystem in Tibet played an irreplaceable role in maintaining global carbon balance and mitigating climate change for its abundant original forest resources with powerful action of carbon *** the present study,the samples of soil and vegetation were collected at a total of 137 sites from 2001 to 2018 in *** on the field survey of Tibet s forest resources and 8^(th) forest inventory data,we estimated the carbon storage and carbon density of forest vegetation(tree layer,shrub,grass,litter and dead wood) and soil(0-50 cm) in *** methods combined with Kriging spatial interpolation and Moran s I were applied to reveal their spatial distribution patterns and variation *** carbon density of forest vegetation and soil in Tibet were 74.57 t ha^(-1) and 96.24 t ha^(-1),*** carbon storage of forest vegetation and soil in Tibet were 344.35 Tg C and 440.53 Tg C,*** density of fir(Abies forest) was 144.80 t ha^(-1) with the highest value among all the forest *** storage of spruce(Picea forest) was the highest with 99.09 Tg C compared with other forest *** carbon density of fir forest and spruce forest both increased with the rising temperature and *** was the main influential *** spatial distribution of carbon density of forest vegetation,soil,and ecosystem in Tibet generally showed declining trends from western Tibet to eastern *** results facilitated the understanding of the carbon sequestration role of forest ecosystem in the *** also implied that as the carbon storage potential of Tibet s forests are expected to increase,these forests are likely to serve as huge carbon sinks in the current era of global warming and climate change.
