利用第八次和第九次全国森林资源清查数据,采用政府间气候变化专门委员会(IPCC)指导各国开展的生物量和碳储量估算方法,估算了河北省乔木林碳储量,分析了碳密度和固碳速率;以《河北省国土绿化规划(2018—2035年)》数据为依据,利用模型法预测了固碳潜力。结果显示:2018年河北省乔木林碳储量为6 167.49万tC,平均碳密度为16.88tC/hm²,平均固碳速率为0.31tC/(hm²·a),至2035年新增乔林的固碳潜力为73.63万tC。研究成果有助于估算“碳中和”进度和评估河北省的实施能力。通过本文的分析探讨,以期丰富我国森林碳汇的研究成果,为碳汇的宏观管理提供科学依据。

Based on the data of the eighth and ninth national forest resource inventory,the biomass and carbon storage estimation methods guided by the Intergovernmental Panel on Climate Change(IPCC) were used to estimate the carbon storage of arbor forests in Hebei Province,and the carbon density and carbon sequestration rate were analyzed. Based on the data of "Hebei Land Greening Plan(2018—2035)",the carbon sequestration potential was predicted by model method. The results showed that the carbon storage of arbor forest in Hebei Province in 2018 was 61.6749 million tC,the average carbon density was 16.88 tC/hm²,the average carbon sequestration rate was 0.31 tC/(hm²·a),and the carbon sequestration potential of the new forest was 0.7363 million tC by 2035. The research results contribute to estimate the progress of carbon neutralization and evaluate the implementation capacity of Hebei Province. Through the analysis of this paper,it is expected to enrich the research results of forest carbon sinks in China,and provide scientific basis for the macro management of carbon sinks.
