Climate change is a serious environmental problems faced by human beings. Increasing the carbon sink of forests and the carbon storage of harvested wood products is an effective approach to alleviate the greenhouse effect. China's forestry carbon pool consists of two subsystems including the forest carbon pool and harvested wood products carbon pool. This study analyzed the developmental level of the forestry carbon pool over the past 20 years by integrating methods including the biomass method,single index model,biomass consumption method and stock change approach. The study also predicted the development trend of the Chinese forestry carbon pool in the next 20 years based on GM(1,1)modeling. We found that in terms of the forest carbon pool subsystems,a trend of steady increases from 1989 to 2013 is evident. The carbon storage of the forest pool was 17.5 billion tons in 2013,approximately 50% more than in 1993. The accumulative carbon emissions from logging residues and forest fires was 10.82 and 88.66 million tons,respectively,accounting for 0.57% of the forest carbon pool. In terms of the harvested wood products carbon pool subsystem,a rapid increase in the past 20 years was found. The total and newly increased carbon stock of HWP was 0.9 billion and 50 million tons in 2013,respectively,equivalent to 2.21 and 3.22 times 1993 levels,respectively. In terms of the Chinese forestry carbon pool system,the carbon storage was 18.48 billion tons in 2013. Prediction based on the GM(1,1)model indicated that the carbon storage of the Chinese forestry carbon pool would grow steadily at a relatively high speed from 2014 to 2033. The carbon storage of Chinese forestry carbon pool will reach 27.8 billion tons in 2033,almost 2.05 times the 1993 level.
