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.
