摘　　要：秸秆或生活垃圾热裂解转化生物黑炭的产业化技术已经成熟，生物黑炭固碳减排方法学是进行自主碳交易的必备技术依据。基于河南三利新能源有限公司生物黑炭的生产工艺，对秸秆燃烧（基线）和转化生物黑炭以及农业应用（项目）整个系统全生命周期的温室气体的排放量和碳汇清除量进行了评价。采用该方法学，对已经进行的秸秆生物质黑炭的生产和稻田施用的总效应初步估计为秸秆产生净碳汇249-398kgCO2-e·t^-1。可以看出秸秆生物黑炭具有显著的固碳减排效果。The industrial technology of straw or domestic waste conversion into biochar by pyrolysis has been mature. The approach of straw biochar amendment for measurement of the carbon sequestration and mitigation provides a theoretical basis for carbon trading. The comparative effect of straw burned（basis） and biochar amendment（program） on greenhouse gas emission and carbon sink in relation to agricuhural application was evaluated on the basis of the manufacturing process of Sanli New Energy Company, Henan Province, China. Using this method, the overall carbon sink was from 249 kg CO2-e to 398 kg CO2-e per ton of straw, indicating that straw biochar has a substantial effect on carbon sequestration and mitigation.
