Abstract: Abstract Studying the internal relationship between urbanization process and cultivated land change can reveal the differential law of different urbanization processes and effectively protect cultivated land resources. Using the land-use change analysis method, this paper analyzed the quantity and quality change of cultivated land during the process of urbanization in the Bohai Rim region from 1990 to 2020 and explored its driving mechanism. The results show that the urbanization level in the Bohai Rim region increases by 31.06%, and 120 km2 farmland will be occupied for every 1% increase in urbanization level. The level of urbanization is higher in Beijing and Tianjin, medium in Liaoning and Shandong, and lower in Hebei. The area of cultivated land decreased year by year, and the decrease in dry land was the largest, followed by paddy land. Hebei, Shandong, and Liaoning have a high contribution rate to the reduction in cultivated land around the Bohai Sea. Population urbanization, spatial urbanization, and other factors have a significant impact on the study area, while economic urbanization and life urbanization show different laws. It is suggested that the development of urbanization can be promoted in a timely and appropriate manner, and the harmonious development of urbanization can be promoted by optimizing the layout of land use and avoiding excessive occupation of cultivated land at the expense of food security and ecological environment.
