Abstract: CO₂,the exhaust gas from industry and fossil combustion,is gradually intensifying the greenhouse effect. However,forests absorb and fix a great quantity of CO₂ in the air,and become a huge carbon sink. In order to slow down the intensifying global climate change,forestry is just experiencing the adjustment and changes of its development direction,and the carbon forestry,which includes four aspects:carbon sequestration forestation,forest carbon sink protection,low-carbon economy development and carbon alternatives,is quietly emerging. With the objective of claiming "ecological homestead" and developing green GDP,investigating the local carbon sequestration ability and calculating the carbon value play a very important role in developing the low-carbon economy and protecting the carbon sink. This article takes Cangxi county in Sichuan province as an example to calculate and research the forest carbon storage,carbon sequestration ability,carbon sequestration potential and carbon sequestration value,and provides scientific basis for the future green GDP measurement,low-carbon economy development and carbon sink financing.
