Economic analysis of Chinese fir forest carbon sequestration：based on Zhejiang’s survey

摘要: 增加森林碳汇已经成为应对气候变化的重要举措。基于在中等立地条件和经营强度的土地类型上进行裸地造林的假设，运用杉木Cunninghamia lanceolata生长模型和修正的Faustman-Hartman模型分析碳补贴和碳税政策对杉木人工林的影响。研究表明：由于木材收益远大于碳汇收益，所以在较大的价格区间内碳汇价格增加对于最优轮伐期和碳供给的影响不显著，但最优轮伐期和碳供给量呈上升趋势；土地期望值与碳汇价格呈正相关。由于碳补贴和碳税政策的实施，林地的价值在增长，与其他土地利用类型如农业用地相比，更多的土地将被用作林业用地。图5表1参16Abstract: Increasing forest carbon-sequestration has become an important measure to address the climate changes. Based on the assumptions of planting in bare lands with medium site conditions and management intensity，this research analyzed the impact of carbon subsidies and carbon tax policies on Chinese fir （Cunninghamia lanceolata） plantation through the Chinese fir growth model and the modified Hartman model. The research findings indicated that raising carbon price had little effect on the optimal rotation and carbon supply in a comparatively large price range because the profit from the wood was much higher than that from carbon sequestration. However，the optimal rotation and carbon supply showed a tendency to rise；the land expected value was positively correlated with the carbon price. Because of the implementation of carbon subsidies and carbon tax policies，the values of forest land had been increased. Compared with other types of land use such as agricultural land，more land should be used as forest land.［Ch，5 fig. 1 tab. 16 ref.］
