摘要: 采用生物量法对经过不同采伐方式(渐伐、皆伐)兴安落叶松林更新林和未采伐的原始林的碳密度及其空间分布特征进行研究。结果表明:兴安落叶松林地上部分碳密度原始林为109.60 t/hm2,渐伐林为58.94 t/hm2,皆伐林为47.50 t/hm2,其中乔木层所占比例最大,凋落物次之,依次为草本和灌木;乔木层碳密度原始林为78.63 t/hm2,渐伐林为33.61 t/hm2,皆伐更新林最低为31.70 t/hm2;灌木的碳密度原始林为1.12 t/hm2、渐伐林为0.63 t/hm2、皆伐林为0.38 t/hm2;草本碳密度原始林为1.02 t/hm2、渐伐林为1.88 t/hm2、皆伐林为0.65 t/hm2;凋落物的碳密度原始林为28.84 t/hm2,渐伐林为22.83 t/hm2,皆伐林为14.77 t/hm2

Abstract: In this paper,biomass method with different harvesting ways(gradually cutting,clear cutting) 800 Larix gmelinii forest was used to study the original forest harvesting carbon density and its spatial distribution characteristics.The results showed that Larix gmelinii virgin forest aboveground carbon density was 109.60 t/hm2,intermediate cutting forest 58.94 t/hm2,clear cutting forest 47.50 t/hm2,in which the proportion of the tree layer is the largest,followed by litter,herbs and shrubs;tree layer of virgin forest carbon density was 78.63 t/hm2,intermediate cutting forest 33.61 t/hm2,updated forest clear cutting minimum 31.70 t/hm2;shrubs the virgin forest carbon density is 1.12 t/hm2,intermediate cutting forest 0.63 t/hm2,clear cutting forests 0.38 t/hm2;herb virgin forest carbon density is 1.02 t/hm2,intermediate cutting forest was 1.88 t/hm2,clear cutting forest 0.65 t/hm2;virgin forest litter carbon density is 28.84 t/hm2,intermediate cutting forest 22.83 t/hm2,clear cutting forest 14.77 t/hm2.
