摘　　要：基于森林资源二类清查数据资料,利用材积源生物量法和平均生物量法,计算新疆喀纳斯国家自然保护区内森林植被的碳储量及其空间分布。结果表明:保护区内森林植被碳储量为3.004 7 Tg,平均碳密度为49.58Mg/hm2。不同植被类型碳储量从大到小排序为:乔木林地、灌木林地、疏林地、散生木,其中乔木林地碳储量占到森林植被总碳储量的90.18%,各乔木林地的平均碳密度为68.87 Mg/hm2。区域分布上,林分碳储量、碳密度的空间分布呈现出西南高东北低的趋势;而保护区内成、过熟林分的碳储量共占乔木林地碳储量的79.89%,若对现有森林采取合理的经营管理,可增加其碳汇能力。Carbon storage and its spatial distribution in forest vegetation of the Kanas National Nature Reserve were estimated by both volume-derived and average biomass methods according to the data from Forest Resource Inventory. Results showed that carbon storage was 3. 004 7 Tg,and mean carbon density 49. 58 Mg / hm^2. The carbon storage was in the sequence of standing forest,shrub forest,open forest and scattered trees. Carbon storage of the standing forests accounted for 90. 18% of the total in this area. The average carbon density of standing forests was 68. 87 Mg / hm^2. Regional distribution of the forest carbon storage and carbon density had a trend of increase from southeast to northwest. The carbon storage of the standing forests was mainly consisted by mature and over matured forests,accounting for 79. 89% of the total forest carbon storage in the area. This implies the proper management of the present forests could increase the carbon sequestration of the forest ecosystems.
