Abstract: The carbon sequestration of Pinus massoniana Forest Management Project in Wanzhou District was measured. The results showed that the carbon sequestration of the baseline scenario was accumulated to 57 552 tC and the carbon sequestration of project scenario was cumulated to 180 572 tC, which was 3.13 times the baseline scenario. Project net carbon sequestration was 123 020 tC,which could be converted into 451 074 t CO₂ equivalent,and the average annual amount of carbon sequestration was 2.89 t CO₂-e per hectare. Through forest management,carbon storage could be effectively increased,and the capacity of carbon sequestration could be enhanced. It was of great significance for establishing the carbon sequestration benefit compensation mechanism,perfecting the carbon trade market,improving the ecological environment and tackling regional climate changes.
