基于江西省婺源县二类森林资源调查结果,结合森林优势树种蓄积量、林龄结构、生物转换量、含碳率、根茎比、木材密度、年均生长率等参数计算江西省婺源县基准年(2005年)森林碳储量和碳汇潜力。结果表明,婺源县森林优势树种总碳存储量约为188.85万t碳,其年碳汇潜力为77.29万t二氧化碳当量,散生木、四旁树、疏林地生物质碳汇潜力为3.04万t二氧化碳当量,婺源县的固碳潜力可达80.33万t二氧化碳当量。另外,婺源县中幼龄林占68.29%,具有较强的固碳潜力。
Based on the results of the investigation of the second category of forest resources in Wuyuan County, Jiangxi Province, the base year of Wuyuan County in Jiangxi Province was calculated based on the parameters such as stock volume, age structure, biomass conversion rate, carbon content, rhizome ratio, timber density and average annual growth rate (2005) Forest carbon stocks and carbon sequestration potential. The results showed that the total carbon storage of predominant species in Wuyuan County was about 1.8885 million tons of carbon and the annual carbon sink potential was 772,900 tons of carbon dioxide equivalent. The potential for carbon sequestration of biomass from scattered trees, treeside trees and sparse forests was 30,400 tons of carbon dioxide Equivalent, Wuyuan County, the potential for carbon sequestration up to 803300 t carbon dioxide equivalent. In addition, Wuyuan County young forest accounted for 68.29%, has a strong potential for carbon sequestration.
