Abstract: Based on the data of forest resources in Wushan County in 2022, the total carbon storage and carbon density of timber forests in Wushan County was estimated by the IPCC volume source biomass method, and the biomass carbon storage of bamboo forest and shrub forest was estimated by the average biomass method. The results showed that: (1) In 2022, the carbon storage of forest biomass in Wushan County was 533.71 × 10⁵ tons, of which the carbon sink function of deciduous forests was dominated, accounting for 90.59% of the total. The carbon storage of bamboo forest and shrub forest was relatively small, accounting for only 0.28% and 9.13% of the total, respectively. (2) Among the carbon storage of forest in Wushan County, natural forest was 259.68 × 10⁵ t and artificial forest was 223.82 × 10⁵ t, accounting for 53.71% and 46.29% respectively. Among the dominant tree species, common ones such as oak, cypress, and Pinus massoniana had larger carbon storage.
