福建省木质生物质原料供应链碳排放研究

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%）。

Analysis of Carbon Emissions of Woody Biomass Feedstock Supply Chain in Fujian Province

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%)．
