Since the late 1990s, the Chinese government has implemented six major forestry projects to increase forest carbon sequestration through afforestation, reforestation, and forest restoration. This paper estimatedthe amount of forest carbon sinks,using forest resource inventory data and forestry engineering data and conversion factors continuous function method. The amount of carbon sequestration of the last 10 years has been estimated to find out the major forest recovery plan's effect of carbon sinks. The results showed that:(1)In the past 10 years, carbon storage and density forest resources in sample have greatly increased. Carbonsequestration of forest has increased 1.00TgC and average carbon density of forest has increased 2.13MgC/hm².(2) There was a significant regional difference in the forest carbon sequestration and carbon density increases due to thenon-equilibriumof the major forest recovery plan. The increase of the forest carbon sequestration and carbon density was occurred mainly in the valley between the Fangdou Mountain and Qiyao Mountain, because the Natural Forest Protection Project and the Grain for Green Projectcarried out more here. (3) Carbon sinks of pine, cedar, cypress and mixed coniferous increased as many as 1.36TgC. Carbon sinks of nearly mature forest and middle-aged forest and young forest increased more.Carbon sinks of middle-aged and young forest increased as many as 0.94TgC. Natural forest can save more carbon the plantation. (4) In the past 10 years, 97.66% carbon sequestration was caused by the major forest recovery plan. The average carbon density has increased 7.64MgC/hm² and it was higher than areas not covered by the major forest recovery plan. Carbon sequestration caused by the Natural Forest Protection Project was the most and it accounted for 85.57% of the total.Carbon sequestration caused by the Grain for Green Project was just 0.05TgC because of the late implementation time and bad effectiveness. (5) Carbonsequestration caused by the major forest recovery plan was mainly focus on middle-aged forest and young forest. Middle-aged forest and young forest have great potential to increase carbon sinks when they evolve into nearly mature forest and mature forest. (6) This study helps people to understand and recognize the effectiveness of the major forest recovery plan, and provides a scientific basis for developing policy to respond to and slow down global change.
