摘　　要：通过野外样地调查及资料收集,采用统计分析和模型估算等方法,研究黄冈市典型城市森林生态系统碳储量及其分布特征。结果表明,遗爱湖城市森林生态系统总碳储量为21815.85 MgC,其中地上生物、地下生物和土壤碳库的碳储量占比分别为18.42%、7.06%和74.52%;龙王山城市森林生态系统总碳储量为8025.51 MgC,其中地上生物、地下生物、枯落物和土壤的碳储量占比分别为23.62%、6.75%、1.30%和68.33%。从各碳库的碳储量来看,土壤碳库碳储量占比最大,其次为地上生物碳库。通过碳汇潜力分析可为评估城市森林生态系统碳汇能力、开展森林健康评价提供理论参考。Through field investigation and data collection,statistical analysis and model estimation approaches were employed to investigate the carbon storage and its distribution characteristics in typical urban forest ecosystems in Huanggang City.The results showed that the total carbon storage of the Yi'ai Lake urban forest ecosystem amounts to 21815.85 MgC.Among them,the carbon storage proportions of aboveground biomass,underground biomass,and soil carbon pools were 18.42%,7.06%,and 74.52%,respectively.The total carbon storage of the Longwang Mountain urban forest system was 8025.51 MgC,where the carbon storage proportions of aboveground biomass,underground biomass,litter,and soil were 23.62%,6.75%,1.30%,and 68.33%,respectively.Concerning the carbon storage from various carbon pools,the soil carbon pool holds the largest proportion,followed by the aboveground biomass carbon pool.The analysis of carbon sink potential can furnish theoretical references to evaluate the carbon sink capacity of urban forest ecosystems and conduct forest health assessments.
