[Objective]The aims of this study are to describe the characteristics of cultivated land utilization transformation, to reveal the pattern of cultivated land transformation and development, and to provide theoretical support and reference for the protection of cultivated land resources and rural transformation and development in Fenhe River Basin. [Methods]Based on the remote sensing data of land use in 1980, 1990, 2000, 2010 and 2020, the spatiotemporal characteristics of land use transition in Fenhe River Basin were analyzed by using the methods of velocity, transfer matrix and geographic detector, and the driving factors were explored. [Results](1)From 1980 to 2020, the area of cultivated land in the basin decreased by 1.059×105 hm2, among which the area of cultivated land converted into construction land was the largest, and grassland was the land type converted into cultivated land, accounting for 59.37% of the total area.(2)From 1980 to 2020, the transformation rate of cultivated land use in Fenhe River Basin showed a fluctuating downward trend, among which the decrease of cultivated land in the middle reaches was the most obvious, and the contradiction between man and land was prominent.(3)The degree of influence of natural factors on cultivated land transformation was significantly stronger than that of social and economic factors, and the temperature q value was the largest, reaching to 0.72. The interaction between natural factors had a stronger explanatory power for cultivated land transformation. [Conclusion]Under the influence of natural and social economic factors, the transformation of cultivated land use in Fenhe River Basin had experienced different stages of smooth easing, intensified transformation, sharp contradiction and convergence balance. The spatial agglomeration features are significant, which will guide the rational and orderly utilization of cultivated land resources in the basin.
