[Objective]Taking county in Hebei as the research unit, we analyzed the range and velocity of cultivated land function supply and demand transition, explored the optimal path of functional utilization of cultivated land. [Methods] Based on the current land use data and social and economic data, the functional supply and demand levels of cultivated land in 2000, 2010 and 2018 were calculated by the value quantity method, and the four-quadrant model was used to realize the zoning of cultivated land use at county scale in Hebei Province. [Results] During the study period, the supply and demand of cultivated land function increased in most counties of Hebei Province, and the distribution of cultivated land function supply was high in the east and low in the west. The functional demand for cultivated land concentrated in Cangzhou, Langfang and Tangshan around Beijing and Tianjin. Chengde City, Qinhuangdao City and Tangshan City had higher transition range of cultivated land function supply in Hebei Province, and Cangzhou City, Langfang City and Tangshan City had higher transition range of cultivated land function demand. The transition speed of cultivated land function supply and demand in most districts and counties of Hebei Province gradually increased. From the perspective of spatial distribution, the transition speed of cultivated land function supply and demand in Chengde City was faster, while that in Langfang and Tangshan City was faster. [Conclusion] The matching of cultivated land function supply and demand in Hebei Province turned from surplus to deficit. The study on the zoning of cultivated land utilization provides an optimization path for four types of functional areas: high supply and high demand, high supply and low demand, low supply and high demand, and low supply and low demand.
