摘  要：
基于墨脱县森林资源二类调查数据等材料,采用材积源生物量法以及生物量转换连续因子法等经验模型,分不同森林植被类型计算各个小班的生物量并综合;再根据不同森林植被类型的含碳率计算各个小班的碳储量以及各森林植被类型的碳密度。结果表明,墨脱县实际控制区总的森林植被生物量为77 582 750.1 t,全县单位面积平均生物量为177.61 t/hm2;总碳储量为39 355 414.3 t,全县碳密度平均为90.10 t/hm2。从结果来看,墨脱县的森林生物生产力较高,森林资源质量较好,尤其是云杉(冷杉)的单位面积平均生物量高达311.60 t/hm2,质量非常好;全县单位面积平均生物量、碳密度均为针叶树较阔叶树大。

摘  要：
Based on the second class investigation data of forest resources in Motuo County and other materials,the biomass of each class and total biomass of different vegetation types were calculated by using some empirical models of the volume derived biomass method,biomass conversion continuous factor method and so on. The carbon storage of each class and carbon density of each forest vegetation type were calculated based on carbon contents of different vegetation types.The results showed that,the total forest vegetation biomass was 77 582 750. 1 t at the actual control areas of Motuo County,the average biomass per unit area was 177. 61 t / hm2,the total carbon reserves was 39 355 414. 3 t,and the average carbon density was 90. 10 t / hm2. So biomass productivity of the forest in Motuo County was higher,the forest resources quality was better,especially the average biomass of spruce( fir) per unit area reached 311. 60 t / hm2,and the quality was very good. The average biomass per unit area and carbon density of conifers was relatively larger than those of broadleaved trees.
