摘  要：
基于三江源自然保护区公益林更新调查数据,采用生物量换算因子连续函数法和平均生物量法估算了三江源自然保护区森林和灌丛生态系统植被层的碳储量和碳密度。结果表明:1)三江源自然保护区森林和灌丛生态系统植被层碳储量约为26.87Tg,平均碳密度22.22t/hm2;2)植被层中,以灌木层碳储量最大,占植被层碳储量的66.06%;3)碳储量地域分布以中铁-军功、白扎、玛可河、通天河、江西等保护分区为主,合计占总碳储量的68.81%;4)天然林在植被层碳储量中占绝对优势,分别占乔木层碳储量的98.49%和灌木层的99.71%;5)林分中碳储量以近、成、过熟林为主,三者合计占林分的57.04%;6)乔木树种主要集中在圆柏属和云杉属,占乔木层碳储量的94.57%;灌木树种集中在山生柳和杜鹃,占灌木层碳储量的76.50%。

摘  要：
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. 87 Tg 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.
