摘　　要：使用目前比较通用的碳排放研究方法,建立1个定量计算模型,分析福建省木质生物质原料供应链不同阶段的碳排放量。结果表明:直接和间接碳排放所占比例分别达66.57%和33.37%,隐含碳排放量所占比例最低,仅占0.06%;在直接碳排放过程中,采伐、集材、运材阶段碳排放量分别占2.36%、4.99%、92.65%;影响原料供应链总的碳排放量的主要指标重要程度排序依次为,采伐指标(37.96%)>运材距离(23.42%)、单位周转量油耗(运材阶段,23.42%)>工人每天消耗的能量(12.67%)>集材距离(1.26%)、单位周转量油耗(集材阶段,1.26%)。This paper used the relatively common research methods to establish a quantitative calculation model to analyze the carbon emissions of different stages of feedstock supply chain in Fujian province. The results showed that embodied carbon emissions shared the lowest proportion, only 0.06%, while the direct and indirect carbon emissions reached 66.57% , 33.37% , respectively. In the process of direct carbon emissions, carbon emissions of harvesting, skidding, hauling stage accounted 2.36% ,4. 99%, 92. 65% , respectively. The order of importance which affects the total carbon emissions of the feedstock supply chain was harvesting index （37.96%） 〉 timber transport distance （23.42%）, unit turnover fuel consumption （transport timber stage ,23.42% ） 〉 daily energy consuming by workers （ 12.67% ） 〉 skidding distance （ 1.26% ）, unit turnover fuel consumption （ skidding stage, 1.26% ）.
