摘　　要：基于2020年墨江县森林资源一张图数据,利用生物量扩展因子法,对墨江县的思茅松生物量、碳储量、碳密度进行估算,分析不同龄组、不同径阶、不同地貌因子(坡位、坡向)四个因子对思茅松生物量、碳储量、碳密度的影响。结果显示:思茅松生物量和碳储量与蓄积量成正比,随着蓄积量的增加呈现增加趋势;墨江县思茅松幼龄林、中龄林、近熟林碳储量占比达到97%以上;思茅松成熟林和过熟林面积在墨江县思茅松林中占比较小,但是碳储量密度较大;墨江县思茅松人工林不同坡向碳储密度差别不大;思茅松人工林和天然林碳储密度在不同坡向均呈现北〉东北〉西北>西>东>西南>南>东南。Based on the forest resource map data of Mojiang county in 2020,the biomass expansion factor method was used to estimate the biomass,carb on storage and carbon density of Pinus kesiya var.langbianensis in Mojiang county,and the effects of four factors including different age groups,different diameters and different geomorphic factors(slope position and aspect)on the biomass,carbon storage and carbon density of Pinus kesiya var.langbianensis were analyzed.The results showed that the biomass and carbon storage were proportional to the stock,and increased with the increase of stock.The carbon storage ratio of young forest,middle forest and near mature forest in Pinus kesiya var.langbianensis of Mojiang county was more than 97%.The area of mature forest and over-mature forest was relatively small in Mojiang county,but the carbon storage density was large.There was no significant difference of carbon storage density in different slopes of Pinus kesiya var.langbianensis plantation in Mojiang county.The carbon storage density of Pinus kesiya var.langbianensis plantation and natural forest showed as follows in different slope directions:north>northeast>northwest>west>east>southwest>south>southeast.
