| 摘 要： | 比较思茅松常规林和计划烧除林上坡、中坡和下坡3个坡位腐殖质层厚度、载量和有机碳储量,以及0～60cm层次土壤有机碳含量和储量,分析坡位在思茅松林计划烧除中对土壤有机碳储量的影响。实验数据表明:思茅松林3个坡位计划烧除后腐殖质层厚度、载量、有机碳储量均增加显著(P<0.05),分别增加了0.55cm,2.298t/hm2,1.466t/hm2;0～60cm层次各个相同坡位土壤平均有机碳含量和储量增加均极显著(P<0.01),增幅均为下坡>中坡>上坡,增加值分别为0.581,0.505,0.482;44.218,41.696,32.492t/hm2。这些实验数据说明计划烧除可增加森林土壤有机碳储量,选择下坡和中坡进行计划烧除可获得更好的固碳效率。

| Abstract: | Comparison was done on three slopes of conventional and prescribed burning forest of humus layer thickness,load and organic carbon storage of upper,middle and bottom slope,and 0~60cm levels soil organic carbon content and storage.This paper elaborated the impacts of slope positions on soil organic carbon storage in prescribed burning of Pinus Kesiya.The experimental data showed that after prescribed burning,humus layer,load and organic carbon storage of three slope increased obviously(P<0.05),which increase... |
