This study addresses the critical need for precise agricultural population distribution data to inform modern agricultural system development and policy formulation. We integrated country-level demographic data from the Seventh National Population Census with the China Land Use Remote Sensing Monitoring Dataset to develop a novel grid-based spatial distribution model. This methodological approach enabled the first comprehensive visualization of China’s agricultural population density at a 1 km resolution, with validation metrics confirming the high statistical reliability of the results. Our spatial analysis revealed three significant geographic patterns: (1) The Hu Huanyong Line (Hu Line) presents a profound demographic divide, with southeastern regions exhibiting an average agricultural population density (30.57 persons·km-2) nearly 15.9 times higher than northwestern regions (1.92 persons·km-2). (2) Agricultural population distribution follows China’s three-tiered topographical gradient, with densities increasing significantly from the western plateau (0.98 persons·km-2) through the central highlands (11.27 persons·km-2) to the eastern plains (30.76 persons·km-2). (3) Environmental determinants strongly influence agricultural settlement patterns, creating a clear dichotomy between densely populated warm, humid, low-altitude agricultural zones, and sparsely distributed cold-arid plateau and hilly agricultural regions. These findings provide an empirical basis for targeted agriculture development strategies: Prioritizing digital agriculture technologies in high-density regions like the Huang-Huai Plain; developing integrated agritourism models in ecologically sensitive areas; and implementing specialized training programs to cultivate a professional agricultural workforce adapted to regional conditions.
