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。
Carbon sequestration can be divided into industrial and biological sequestration. Industrial sequestration includes geological storage, marine sequestration, carbonization of ores, and industrial recycling. These methods can rapidly recover CO2, but the technology is complicated and the cost is high. Wood carbon sequestration is a type of biochar sequestration, and the photosynthetic carbon absorbed by trees is mainly stored in wood. By using wood density and microdensity detection instruments, the determination of wood density, combined with its carbon content, to measure the carbon sequestration process and carbon distribution pattern in the process of wood storage, and to study its correlation with environmental factors, The dynamics of forest carbon uptake provide a convenient method and a scientific basis.
