粮食安全是推进中国式现代化的重要保障, 农业碳汇价值实现是推动粮食安全的重要手段。当前, 我国农业碳排放量占总碳排放量的17%, 不合理的农业碳排放与环境污染问题对我国粮食安全构成直接威胁, 因此, 在农业可持续发展问题愈发凸显的今天, 将农业碳汇价值实现与粮食安全议题进行结合研究显得尤为必要。本文立足于粮食安全目标的大背景, 从农业碳汇价值实现的重要性入手, 对农业碳汇内涵与机理进行了梳理, 针对我国农业碳汇价值实现面临的机制困境, 总结了美国、欧盟、澳大利亚、日本等国在法律、财税、市场交易、科技、管理等方面的主要做法和先进经验, 提出了以下对策: (1) 建立完备的农业碳汇法律法规体系; (2) 建立科学的农业碳汇核算体 系; (3) 构建高效的农业碳汇市场交易体系; (4) 建立完善的农业碳汇保障机制; (5) 构建完善的农业社会化服务体系等, 以期为推动我国农业碳汇价值实现提供参考。

Food security is an important guarantee to promote the Chinese-style. modernization, and the realization of agricultural carbon sink value is an important means to promote food security. At present, China' s agricultural carbon emissions account for 17% of the total carbon emissions, incorrect agricultural greenhouse gas emissions and environmental pollution pose a direct threat to China' s food security. Therefore, as the issue of agricultural sustainable development becomes increasingly prominent, it is particularly necessary to combine the realization of agricultural carbon sink value with food security issues for study. Based on the background of food security goals, this paper starts with the importance of realizing the value of agricultural carbon sinks, sorts out the connotation and mechanism of agricultural carbon sinks, and summarizes the main practices and advanced experiences of the United States, the European Union, Australia, Japan and other countries in terms of law, finance and taxation, market, technology, and management in view of the mechanism dilemma faced by China' s agricultural carbon sink value realization. The following countermeasures are proposed: (1) Establish a complete legal system for agricultural carbon sinks; (2) Establish a scientific agricultural carbon sequestration accounting system; (3) Building an efficient agricultural carbon sink market system; (4) Establish a comprehensive agricultural carbon sequestration guarantee mechanism; (5) Building a comprehensive agricultural socialized service system, etc. , in order to provide reference for promoting the realization of China' s agricultural carbon sink value.
