摘要

本文係探討國內柳杉疏伐中小徑木之有效利用的方式及碳素因定量估算。主要利用方式為壁板，中小學課桌椅，野餐桌及小板凳。研究結果得知，原木製材利用率分別為38%、35%、30%和42%，碳素因定量則分別為283.5kg/批、5.6kg/套、30.6kg/套和0.9kg/套，換算為CO2當量則分別為1,039.5kg/批、20.6kg/套、112.2kg/套和3.2kg/套。

This study investigated carbon sequestration benefit from effective utilization of medium-small diameter of Japanese cedar thinned log. Utilization efficiencies of logs manufactured into wall panels, school furniture, picnic tables, and wooden stools were compared. The results shown that the saw lumber utilization efficiencies for wall panels, school furniture, picnic tables, and wooden stools were 38%, 35%, 30%, and 42%, respectively. The carbon sequestration amount for wall panels (per square meter), school desk and chair (one set), picnic table (one set), and wooden stool (one set) were 1.86kg, 5.6kg, 30.6kg, and 0.9kg, correspondingly. Equivalent carbon dioxide fixation amounts were 6.82kg/m^2, 20.6kg/set, 112.2kg/set, and 3.2kg/set, respectively.
