| 摘 要： | 生物地球化学循环是物质（元素）在大气圈、水圈、生物圈与岩石圈之间流动的根本理论，对实现国家碳达峰、碳中和目标有重要指导作用。农业作为基础产业对大气温室效应的时空尺度较大，农业碳达峰、碳中和值得关注和重视，以服务于国家碳达峰、碳中和发展总体战略。文章基于生物地球化学循环视角和农业碳达峰、碳中和释义，分析了农业碳达峰、碳中和路径，从农业碳达峰面临挑战、农业碳中和面临挑战、农业碳中和潜力分析、农业碳中和误区及生物圈减排的重要性等5个方面进行了深入思考，并从农业碳达峰、农业碳中和与科技创新3个方面提出我国农业碳达峰、碳中和的应对策略。

| Abstract: | Biogeochemical cycle is the basic theory of matter (elements) flow among atmosphere, hydrosphere, biosphere and lithosphere, which provides important guidance to achieving the national goal of agriculture carbon peak (ACP) and agriculture carbon neutrality (ACN). As a basic industry, agriculture has large-scale temporal and spatial influence on the greenhouse effect, hence great importance should be attached to ACP and ACN in order to assist the overall strategy of achieving national carbon peak and neutrality. Based on the view of biogeochemical cycle and connotations of ACP and ACN, this article analyzes the paths to achieve ACP and ACN, and discusses the following five aspects:the challenges of ACP, the challenges of ACN, potentials of ACN, misunderstandings of ACN, and biosphere''s important role in CO2 reduction. The article also makes strategy suggestions for realizing our national goal of carbon peak and neutrality from the perspectives of ACP and ACN, as well as science and technology innovation. |
