Abstract: The security of cultivated land resources is closely related to a country’s food security, economic security and social security, and as such is always the top priority of those responsible for the governance and administration of state affairs. The study area is 13 prefecture-level cities in Hubei Province. An entropy weight method, comprehensive index method, spatial analysis and obstacle degree model are employed to explore the spatio-temporal characteristics and obstacle factors of cultivated land resources in quantity, quality and ecological security. The study shows that (1) the security level of cultivated land resources in Hubei Province showed an upward trend between 2010 and 2019. The land resources’ quality and ecological security showed an upward trend, while quantity security showed a downward trend. (2) The security of cultivated land resources presents obvious spatial differences, generally showing a decreasing trend from west to east. Among them, quantity security presents a spatial pattern of being high in the central, low in the east and lower in the west of Hubei Province. Quality security presents a spatial pattern of being high in the central region and low in the east and west. Ecological security presents a spatial pattern of being high in the west and low in the east. (3) The main obstacles to its security in quantity, in quality and in ecology are obviously different. Finally, some countermeasures are put forward to ensure the security of cultivated land resources from the perspectives of quantity, quality and ecological security, and to assist with the implementation of different protection policies in the western, central and eastern areas of Hubei. This study expands the content and perspective of cultivated land resources security and has a certain novelty in the selection of the index of water resources per unit of land area, and the application of the obstacle degree model expands the research on the influencing factors of cultivated land resource security.
