| Based on the data in 2002 and 2012 of forest inventory in Chongqing, using a regression model between stand biomass and volume which was appropriate for the southwest district, this paper estimated forest vegetation carbon storage dynamics in recent 10 years in Youyang county. And then carbon dynamics of different sorts of vegetation was calculated. The results indicated that, in the recent 10 years, total of forest carbon increased strikingly, and among whole species, China fir's increment was the maximum, among all ages, middle-age forests had the largest increase. Then it can be concluded that, the forest in Youyang is a carbon sink, and with the
growing of young forests and development of plantation, the function of carbon sink will rise. |
