Abstract
Kanas National Nature Reserve located in the arid area, Xinjiang province, Northwest of China. The taiga forest in southern mountain area was important vegetation in the Kanas Reserve. The main forest type was Larix sibirica Ledeb., their main associated tree species were Picea obovata Ledeb., Abies sibirica Ledeb., Pinus sibirica (Loud.) Mayr., Betula pendula Roth., Populus tremula Linn., and so on. These forest vegetation had high scientific research value on the terrestrial ecosystem. If biomass and carbon storage of the forest vegetation could be assessed properly, it would be provide basic data for forest resource management, global carbon cycle research, and carbon sink evaluation. In this paper, the biomass and its distribution of different forest type were evaluated based on the measured data using the method of relative growth and full bined with the stands investigation data. Carbon storage and carbon density were calculated by biomass and their carbon content of different tree species. The characteristics of spatial distribution of carbon storage were explained based on the topographical map of forest management in the Kanas National Nature Reserve. The results show that:
The biomass distribution changed within an of P. obovata, L. sibirica, P. sibirica, and B. pendula. But the biomass of trunk was higher than the ans. The rank of biomass of an of P. obovata is trunk> roots> branches> bark > leaf, L. sibirica is trunk> roots> bark > branches > leaf, P. sibirica is trunk> branches > roots > bark > leaf, and B. pendula is trunk> roots> bark > branches > leaf. There were no significant difference between the biomass of branch and root of P. obovata, and P. sibirica (p>), and significant difference among the biomass of an of L. sibirica, and B. pendula(p<).
There were correlationship between DBH or D2 and biomass of individual tree, and their relationship showed by power function model. The functions of 4 main forest
type were as follows:
