摘　　要：以云南景谷县思茅松林为典型案例,从追求最大固碳效率为出发点,研究和评价计划烧除林和常规林2种森林管理模式林下各类可燃物含水率、载量、碳贮量和腐殖层厚度等。试验结果表明:经计划烧除后林下枯落物载量和细小可燃物载量跟常规林没有明显区别,且可燃物载量变化幅度相对稳定,但腐殖质层的高载量致使林下可燃物载量比常规林高2.92t.hm-2,平均碳贮量比常规林高1.943 t.hm-2,且腐殖层厚度比常规林厚0.526 cm,说明计划烧除可增加森林的固碳量,达到森林增汇效益。Taking Pinus Kesiya Royle ex Gord.Var.langbianensis in Jinggu,Yunnan as the typical case,from the starting point for obtaining the maximum efficiency of carbon sequestration,this paper researched and evaluated the fuel moisture content,load,carbon and humus layer thickness with 2 different forest management models including prescribed burning forest and conventional forest.Experimental results showed that after prescribed burning,litter load and fine fuel load had no significant difference with conventional forest,and the fuel load change amplitude was relatively stable,however,the humus story high loads resulted in understory fuel load＇s being 2.92t·hm-2 higher than the conventional forest,the average carbon storage＇s being 1.943t·hm-2 higher than the conventional forest,and the humus layer thickness＇s being 0.526cm more than the conventional forest,the data on these three areas prescribed burning increase carbon sequestration of forests,and achieve forest efficiency.
