Considering that the development model of forestry carbon sink project affects the cost and resource allocation efficiency of the project supplier,it is very important to explore an effective forestry carbon sink project development model.A good model could improve the enthusiasm of forest carbon sink service supply in the carbon trading market and promote the sustainable and healthy development of the carbon sink service industry.This paper abstracted one development model of "local government + forest industry enterprise + technical service agency + green carbon sink foundation" by,taking the Tangwang River Forestry Carbon Sequestration Project as an example.It analyzed the specific role of each constituent institution in the project development,the linkage mechanism among the various institutions,and the problems in the development model.In response to the existing problems,it proposed a new forestry carbon sink project development model led by forest industry enterprises and optimization countermeasures.According to this research,it's expected to provide reference for the selection and optimization of other forestry carbon sink project development models.
