摘　　要：实现“双碳”目标需要提高生态碳汇,生物炭可以作为固碳材料实现生态碳增汇。将生物质废弃质制备成生物炭可实现材料固碳,生物炭施入土壤后可提高土壤有机碳同时减少二氧化碳排放,估算我国每年粮食作物秸秆生物炭还田的固碳减排潜力约为4.78×10^(8)t。提出了农田土地利用结构的合理化、强化农田生物固碳减排技术、生物炭与其他物质施用配施等农田土壤固碳减排管理措施的建议。To achieve the carbon peaking and carbon neutrality goals,ecological carbon sinks need to be improved.Biochar can be used as a carbon sequestration material to achieve ecological carbon sinks.The preparation of biochar waste material into biochar can achieve material carbon fixation,biochar application can increase soil organic carbon and reduce carbon dioxide emissions.It is estimated that the annual carbon fixation potential of food crop straw biochar returning to the field is about 4.78×10^(8) t.Some suggestions on soil carbon sequestration and emission reduction management were put forward,such as rationalization of farmland land use structure,enhancement of farmland biocarbon sequestration and emission reduction technology,and combination application of biochar and other substances.
