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.
