The spring up and rapid development of forestry carbon sinks would give significant effects on the development of the project. Based on the analysis of the carbon sinks, a proposal for speeding up the development of forestry carbon sinks was put forward, aimed to promote the construction of the Three-North Shelter Forest Program.
