Study on carbon storage ability of dry dipterocarp forest in Central Highlands in Vietnam
Keywords:
Carbon,, Carbon storage, Central Highlands, Dry dipterocarps forestAbstract
The results of this study show that carbon stocks in six major woody species in dipterocarp forest concentrate mainly in stems which account for from 49.38% to 94.95%, following by carbon stocks in branches which range from 13.25% to 21.50%; carbon stocks in roots range from 11.51% to 15.88% and carbon stocks in bark account for from 7.2% to 17.84%.
Carbon stocks in leaves, on the other hand, account for from 1.54% to 3.72%. Carbon storages in major woody species vary widely between stem diameter groups as well as species. In average, the highest amount of carbon storages in individual trees is 243.41kg tree -1, which belongs to Dipterocarpus obtusifolius, following by carbon storage in individual trees
of Dipterocarpus tuberculatus(212.59kg tree -1). By comparison, the figures for the other major species rage from 149.26kg tree -1 to 166.58kg tree -1. The rate of carbon below ground and carbon aboveground of individual trees is 0.19. The results of study on carbon structure reveal that 67.08% and 28.39% of total carbon in dipterocarp forest are carbon in soil and woody species, respectively, while the others carbon pools account for only 4.53%. In average the carbon storage in dipterocarp forest in Central Highlands in Vietnam is 84.52 tonsC ha -1. The study also establishes some allometric
equations to estimate carbon sequestration of dipterocarp forest in Central Highlands in Vietnam.
