Abstract: Forestry carbon sink has multiple functions, such as mitigating and adapting to climate change, restoring vegetation and protecting biodiversity, and realizing the sustainable development of communities, which is of great significance to achieve the carbon neutrality goal. Combined with literature research and project practice, the performance evaluation index system of forestry carbon sink project was established from the four evaluation dimensions of management, implementation, effect and impact, which consist of 4 criterion layers, 12 scheme layers and 40 evaluation elements by Analytic Hierarchy Process(AHP), aiming at better serve the development of forestry carbon sequestration project, and provide reference and guidance for theoretical research and practical activities related to forestry carbon sequestration.
