Abstract:

Carbon storage and carbon density of forest vegetation in Sanjingyuan Nature Reserve were estimated by both the continuous biomass expansion factor method and the average biomass method according to the data from public welfare forest reproduction survey.The results showed that,1)The total carbon storage and the average carbon density of forest vegetation was respectively 26.87Tg and 22.22 t/hm2; 2)Carbon storage was highest in shrub layer,which accounted for 66.06% of vegetation layer in this area;3)Carbon storage was mainly distributed in the Zhongtie-jungong,Baizha,Makehe,Tongtianhe and Jiangxi areas,which accounted for 68.81% of the total carbon storage;4)Carbon storage was distributed mostly in the natural forest,which took the percentage of 98.49% in stands layer and 99.71% in shrub layer;5)The carbon storage of the standing forests was relatively concentrated in the near-mature forest,mature forest and over-mature forest,making up 57.04% of the total;6)Carbon storage was greatly located in Sabina spp.,Picea spp.,Rhododendron spp.,Salix oritrepha; which separately occupied 94.57% and 76.50% in the tree layer and the shrub layer.

Key words: Sanjiangyuan Nature Reserve, forest vegetation, carbon storage, carbon density
