摘　　要：该文立足我国碳达峰、碳中和目标,从森林这一实现该目标的主体为对象,定性分析了传统木材节约代用思路和“双碳”背景下的木材节约代用思路。进而以木材碳效益、净化空气效益等为要素建立了木材节约代用的效益分析模型,以木材代用碳成本、经济效益成本为要素等建立了木材节约代用的成本分析模型。基于“双碳”目标,建立了木材节约代用成本效益分析综合效能评价模型。最后,以木制筷子的塑料化替代为例,利用木材节约代用成本效益分析综合效能评价模型计算得到:塑料制品替代木筷消耗的1 m^(3)林木时将增加0.96 t碳,应该摒弃这种传统的木材节约代用路径。In the context of China's carbon peak and carbon neutrality goals,forests have attracted attention as the main body in achieving these goals.Qualitative analysis was conducted on the traditional wood conservation and substitution ideas,as well as the wood conservation and substitution ideas under the background of“dual carbon”.Furthermore,a benefit analysis model for wood conservation and substitution was established based on factors such as wood carbon efficiency and air purification efficiency.A cost analysis model for wood conservation and substitution was established based on factors such as wood substitution carbon cost and economic benefit cost.Based on the“dual carbon”goal,a comprehensive efficiency evaluation model for cost-benefit analysis of wood conservation and substitution has been established.Finally,taking the plastic substitution of wooden chopsticks as an example,using the cost-benefit analysis and comprehensive efficiency evaluation model of wood saving substitution,it is calculated that when plastic products replace 1 cubic meter of wood consumed by wooden chopsticks,it will increase 0.96 tons of carbon.This traditional wood saving substitution path should be abandoned.
