木材碳封存研究进展

Advances in Carbon Sequestration in Wood

碳封存可以分工业封存和生物封存,工业封存包括地质封存、海洋封存、矿石碳化以及工业循环利用,这些方法能快速回收CO2,但工艺流程技术复杂,成本较高。木材碳封存是生物碳封存的一种类型,树木光合作用吸收的碳主要存贮在木材中。运用木材密度、微密度等检测仪器,通过确定木材密度变化,结合其含碳率来计量木材的碳封存过程以及封存过程中碳的分配格局,同时研究其与环境因子的相关性,可以为研究森林的碳吸收动态提供便捷的方法和科学的依据。

Industrialized methods for carbon sequestration include geological sequestration , sea sequestration , ore carbonizing and industrial recycling. The methods can reclaim CO2 as quickly as possible, but with complex techniques and high costs. Forest, a kind of biological carbon sequestration, is the largest storeroom for carbon, and carbon compounds generated by photosynthesis are mainly in wood stem. By determining wood ring density with instruments and measuring carbon content in ring, the change of wood density and the process of carbon sequestration in wood can be researched. At the same time, it is important to study the relationship between carbon sequestration in wood and environmental factors. The research will bring forward more convenient methods and more scientific data for carbon sequestration in forest.
