【摘要】 农业生态系统既是温室气体的重要贡献者之一，也是固碳端，在固碳减排上发挥着重要作用。在“碳达峰”和“碳中和”的背景下，农业生态系统的固碳减排潜力巨大。本文主要综述了中国典型农业生态类型中主要温室气体的来源、固定途径及其影响因素，讨论了农业生态系统固碳减排的现有研究成果、减排潜力以及存在问题，总结了推动整个农业生态系统固碳相关领域的研究，展望了新的研究方向和探索途径。为中国进一步固碳减排、农业可持续发展，尽快实现“双碳”目标提供重要理论参考。更多还原

【Abstract】 Agro-ecosystem is not only one of the important contributors to greenhouse gases, but also plays an important role in carbon sequestration and emission reduction. Under the background of“CO2emission peak”and“carbon neutrality”, agro-ecosystem has great potential for carbon sequestration and emission reduction.In this paper, we mainly reviewed the sources, fixed pathways, and influencing factors of main greenhouse gases in China’s typical agro-ecological types. Meantime, the specific contents were discussed including the existing research results, emission reduction potential and existing problems of carbon sequestration and emission reduction in agro-ecosystem. New research directions and exploration approaches were summarized to promote the research in the field of carbon sequestration in the entire agroecological system. It provided an important theoretical reference for China to further carbon sequestration and emission reduction, sustainable development of agriculture, and the realization of the“double carbon”goal as soon as possible.更多还原
