Reducing agricultural carbon emissions and improving the capacity of agricultural carbon sinks are important measures for China to realize the goal of “Dual-carbon”， which is also where the potential lies. Therefore， it is undoubtedly of great significance to clarify the current status of research on agricultural carbon issues and its characteristics. In order to contribute to the early realization of China’s “Dual-carbon” goal， this paper comprehensively comprehends the existing studies based on the three dimensions of agricultural carbon emissions， agricultural carbon sinks， and driving factors of agricultural low-carbon development. Specifically， firstly， the basic concepts of agricultural carbon emissions are clarified and common measurement methods are introduced， and the current research status is reviewed， taking into consideration temporal evolution， spatial distribution， efficiency characteristics， and emission reduction pathways. Secondly， the basic concepts of agricultural carbon sinks are defined， and the forest carbon sink， soil carbon sink and ocean carbon sink are derived， followed by the introduction of their respective measurement method. Then， the focus is on the net agricultural carbon sink and the marketization of carbon sink. Finally， the main factors that affect the development of low-carbon agriculture are discussed from both macro and micro levels. At the macro level， policy， economic and social factors are considered， while at the micro level， the internal factors of the head of the household and the external environment faced by the farmers are examined. With regards to the direction of future research on agricultural carbon issues， this paper believes that it should focus on the following four aspects， namely， the scientific prediction of agricultural carbon peaks and the design of differentiated emission reduction paths， the scientific assessment of the potential for agricultural carbon reduction and carbon sequestration and the discussion of paths to achieve these goals， the construction of an agricultural carbon market， and exploration of the idea of realizing the value of carbon sinks， as well as the exploration of the matching of the supply and demand of low-carbon production techniques by farmers and the optimization of their systems.
