Increase of forest carbon sequestration is widely accepted as an important strategy for mitigating climate change. Based on rural householdsand national state forest farmssurvey data collected in the provinces of Zhejiang, Fujian and Jiangxi, Faustmann model was applied to analyze the optimal rotation age and forest land expectation value between traditional timber management and combined timber and carbon management for Chinese fir in this study. It compared the carbon supply potential capacity difference of forest management subjects, and sensitivity analysis was also conducted with different interest rate and management cost to simulate the influence on the carbon supply. It was found that the optimal rotation of Chinese fir in the joint management for households and national state forest farms has not changed due to the fact that timber price is much higher than carbon price, suggesting that optimal decision for Chinese fir management will not change significantly and carbon sequestration supply for current forest land would not change within a large range change of carbon price. The object of carbon benefit and traditional management can be coordinated. National state forest farms is much more suitable for carbon supply due to the advantage of management scale, technologies and capital. The potential invest value of carbon forest is much more higher in the low interest rate, and higher management cost can make higher carbon supply.
