Carbon Accumulation, Storage, and Release by Woody Detritus in the Forests of Russia

9652618 哈蒙 俄罗斯森林木质碎屑的碳积累、储存和释放 最近对全球碳循环的分析表明，北方半球必定存在一条从大气中清除二氧化碳的主要途径。 这一清除量的一个主要未知数是俄罗斯森林的清除量，俄罗斯森林占全世界北方森林的50%以上。 该项目解决了全球碳预算中的这一重大未知数。 将开展两项相互关联的研究。 第一项研究量化和总结了这些森林的木本生物量在整个俄罗斯使用广泛的现有数据库。 第二项研究测量了这些森林中木质碎屑的分解率。 这项研究评估了世界上一个主要森林地区的碳的大小和通量。 这些数据将有助于减少全球碳预算的一个主要组成部分的不确定性。

9652618 Harmon Carbon Accumulation, Storage, and Release by Woody Detritus in the Forests of Russia Recent analyses of the global carbon cycle indicate that a major pathway for removal of carbon dioxide from the atmosphere must exist in the Northern Hemisphere. A major unknown for this removal term is the amount being removed by the forests of Russia which comprise over 50% of boreal forests worldwide. This project addresses this major unknown in the global carbon budget. Two interrelated studies will be carried out. The first study quantifies and summarizes the woody biomass of these forests throughout Russia using an extensive existing data base. The second study measures the rates of woody detritus decomposition in these forests. The research assesses the size and flux of carbon in a major forest region of the world. These data will help reduce the uncertainty in a major component of the global carbon budget.
