Abstract
The potential of forest carbon sink in the next 50 years is predicted by using the ninth inventory data of forest in Shanxi Province under the background of the forest resource utilization trends and business models in recent years. The method of the volume derived biomass is used, and the natural and artificial forest is distinguished. The results show that, taking the year 2015 as the base period, the carbon sink of the newly planted dominant tree species will reach 6,269.73×104t in 2065, the carbon sink of the original vegetation is 2,469.73×104t, and the comprehensive carbon sink reach 8,739.47×104t; so the new afforestation achieved by adding a certain area of forest land (even if the area is small, only 2.40%) contributes much more than the original forest vegetation. It is necessary to continuously increase new afforestation area to exert its carbon sink function on the basis of ensuring effective management of existing forest vegetation.
