摘　　要：综述回顾我国农业碳排放的主要特征及类型,并指出农田利用、畜禽养殖、农业废弃物处置和土地利用管理等4方面的农业碳减排潜力。合理的农艺管理和经济政策措施可以减少农田利用碳排放;源头农业碳减排、过程控制和末端处理等措施可以降低畜禽养殖碳排放;优化粪便管理模式和农业秸秆利用可以减少农业废弃物处置碳排放;优化土地资源利用结构、实现土地集约利用和建设高标准农田是土地利用管理碳减排的重要举措。综述可为提升我国农业碳减排潜力提供参考。This review provided an overview of the main characteristics and types of agricultural carbon emissions in China.It also identified potential areas for carbon reduction in agriculture,named farmland utilization,livestock and poultry breeding,agricultural waste disposal,and land use management.Reasonable agronomic management and economic policy measures can effectively reduce carbon emissions from agricultural land use.Measures such as reducing agricultural carbon emissions at the source,implementing process control,and employing end-of-pipe treatment techniques are effective in mitigating carbon emissions from livestock and poultry farming.Additionally,optimizing manure management and agricultural straw utilization can minimize carbon emissions from the disposal of agricultural waste.Furthermore,adopting an optimized structure for land resource utilization,implementing intensive land use practices,and constructing high-standard farmland are crucial measures for carbon reduction in land use management.This article serves as a valuable reference for enhancing the potential of carbon reduction in China’s agriculture.
