摘　　要：为精确掌握石屏县乔木林生物量状况和碳储量情况,基于石屏县2020年度的森林资源数据,采用生物量扩展因子法,对石屏县县域内9个主要乔木树种(组)云南松、桉树、油杉、杉木、栎类等的面积、蓄积、碳储量进行统计和估算。结果显示:在石屏县9个优势乔木树种(组)中,云南松面积最大,其它硬阔类面积最少;云南松和栎类总蓄积量远超其它树种;云南松碳储量最大,碳汇价值最高。建议通过合理优化石屏县乔木林地树种结构配置,加强乔木林地抚育管护力度,提高该县乔木林地固碳潜力。In order to accurately grasp the biomass status and carbon storage of trees in Shiping County,based on the forest resource data of Shiping County in 2020,the biomass expansion factor method was used to calculate and estimate the area,stock volume,and carbon storage of nine main tree species(groups)in Shiping County,including Pinus yunnanensis,Eucalyptus robusta,Keteleeria fortunei,Cunninghamia lanceolata,Quercus spp.,and so on.The results showed that among the nine dominant tree species(groups)in Shiping County,the area of P.yunnanensis was the largest,and that of'other hard broadleaf species'was the least.The respective total stock of P.yunnanensis and Quercus spp.was significantly higher than that of the other groups.P.yunnanensis had the largest carbon storage,with the highest value of carbon sink.It is suggested that the carbon sequestration potential of forest land in Shiping County should be improved by optimizing the tree species structure configuration and strengthening the management and protection of the forest lands.
