Abstract: Based on the analysis of forest resource data in Wushan County in 2022, this paper uses the IPCC volume source biomass method to estimate the total carbon storage and carbon density of deciduous forests in Wushan County, and uses the average biomass method to estimate the biomass carbon storage of bamboo forests and shrubbery forests. The research results show 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 dominated, accounting for 90.59% of the total, while the carbon storage of bamboo forests and shrubbery forests accounted for a relatively small proportion, only 0.28% and 9.13% of the total, respectively. 2. In the carbon storage of deciduous forests in Wushan County, natural forests account for 259.68 × 10⁵ t > artificial forests account for 223.82 × 10⁵ t, accounting for 53.71% and 46.29% respectively. Among the dominant tree species in Wushan County, common ones such as oak, cypress, and pine have larger carbon storage.
