作为第一产业的农林业是唯一的碳汇产业，具有碳减排与碳吸存双重功能，在实现国家碳中和目标中处于重要位置。农林碳中和工程是指在农田、森林和不宜农林但能生长抗逆性强的能源灌草的待开发边际性土地等3片土地上，通过科学的管理与经营，以大幅度增加碳减排与碳吸存力度的综合性工程。面积分别是1.35亿hm²、1.86亿hm²和1.44亿hm²的3片农林碳中和场具有年增汇37.4亿t二氧化碳，年增12.1亿t标煤生物质能的潜力。农林碳中和工程是集保护环境、能源换代、做强农业-乡村振兴-惠及农民于一役的国家工程，乃国之重器。

To be a unique carbon sink, agriculture as the first industry has double performance to reduce carbon emission and to absorb as well as resolve carbon. It thus exists as an important pillar for realizing national target of carbon neutrality. The socalled agro-forestry engineering for carbon neutrality refers to a comprehensive engineering that considerably increases the capacity of carbon emission reduction and carbon reservation through science-guided plantation on three kinds of land, i.e., arable land, forest land, and marginal land which is not suitable for crop cultivation but can be planted with dedicated energy bushes and grasses for their strong resilience. The size of such three carbon neutral grounds totals 465 million hectares, or 135 million, 186 million and 144 million hectares, respectively. The potential capability for adding carbon sink and biomassconverted energy are respectively 3.74 billion tons and 1.21 billion tce annually. The agro-forestry engineering simultaneously comprises environment protection, energy upgrading, agriculture fortification, countryside revitalization and benefiting peasants, thus it is regarded as a national treasure.
