| Abstract: |
| Carbon peak and carbon neutral targets have put forward new objectives for the green development of agriculture in China; therefore, it is very important to achieve synergetic development between agricultural greenhouse gas（GHG）emission reduction, carbon sequestration, and policies for agricultural green development. This study comprehensively analyzed and compared the accounting framework of agricultural GHG emissions and the research progress of the measures of agricultural GHG emission reduction and carbon sequestration by means of literature summaries and policy analysis and described the evolution process of agricultural green development policies related to agricultural GHG emission reduction and carbon sequestration since 1978. The synergistic relationship between agricultural green development policies and agricultural GHG emission reduction and carbon sequestration targets was qualitatively evaluated, and the changing trend of agricultural GHG emission reduction and carbon sequestration under the coordination of different agricultural green development policies was simulated in a black soil area. The results showed that the targets of GHG emission reduction and carbon sequestration in agriculture were coordinated with most of the current targets of agricultural green development policies, but there were some targets that were not included or even negatively coordinated in rice planting, livestock and poultry breeding, straw utilization, and adjustment of planting structure. Through the adjustment of policy objectives, under different combinations of agricultural GHG emission reduction and carbon sequestration technologies in comparison with historical trends, it can promote the decoupling of agricultural GHG emission reduction and carbon sequestration in the black soil region, and finally achieve a win-win situation of agricultural GHG emission reduction and carbon sequestration. Based on these results, several suggestions are proposed, including paying attention to the fundamental role of agricultural GHG emission reduction and carbon sequestration in the carbon peak and carbon neutral targets, expanding the dimensions of agricultural policies, incorporating agricultural GHG emission reduction and carbon sequestration into the targets of agricultural policies, and coordinating the relationship between the two objectives. It is expected to provide a reference for the policy formulation of agricultural green development against the background of carbon peak and carbon neutrality. |
