生物量估算是研究森林生态系统结构和功能的基础,森林生物量约占全球陆地植被生物量的90%,对维持全球碳平衡方面具有重要作用。由于人类活动的影响,我国亚热带森林类型多样,比较各森林生物量的差异和分配特征,可为评估森林碳收支提供基础数据。本研究在湘中丘陵区选择杉木（Cunninghamia lanceolata）人工林、马尾松（Pinus massoniana）-石栎（Lithocarpus glaber）针阔混交林、南酸枣（Choerospondias axillaris）落叶阔叶林、石栎-青冈（Cyclobalanopsis glauca）常绿阔叶林,利用各优势树种的相对生长方程和1hm^2的样地数据估算森林生物量。结果表明：4种森林生物量为72.74-154.03 t/hm^2,各...

Forest biomass is the fundamental data used to study ecosystem structure and function. It is estimated that forest biomass accounted for about 90% of the global terrestrial vegetation biomass. Thus, forest hiomass plays an important role in maintaining the balance of global carbon cycle. In subtropical area of China, there are diverse forest types that regrew after different intensities of human disturbance. Understanding the differences and allocation of forest biomass could provide basic data for estimating income and expend of forest carbon....
