The challenges of limited cropland resources and ecological degradation in grain-producing areas were addressed this study within the broader context China’s civilization dual carbon goals. An integrated framework was employed, applying three-dimensional footprint (EF3d) model, enhanced by improvement, to assess at provincial, municipal, county levels. analysis indicated a rise both absorption emissions, resulting surplus. Since 1984, chemical fertilizers have been identified as predominant source emissions. Carbon found vary distinctly among four crops. Additionally, fluxes displayed notable spatial temporal variability. deficit persisted, showing distinct clustering. Moreover, breadth (EFsize) exhibit pattern decrease–increase–decrease, while occupation remained high. depth (EFdepth) consistently surpassed threshold 1. Spatially, distribution EFsize opposite that EFdepth; centroid per capita EFdepth underwent significant shift. EF3d observed experience downward trend, with considerable regional disparities. Furthermore, unsustainable use across multiple scales. This research provides an empirical foundation for promoting advancing agriculture sustainable practices.
