[Objective] The study on the spatial-temporal change characteristics of land use/cover is of great significance for the protection and rational development of land resources in the Yellow River Basin, and can provide an important reference for the implementation of ecological protection and high-quality development strategy in the Yellow River Basin. [Methods] Based on the annual land use/cover data of the Yellow River Basin from 1980 to 2021, the characteristics of land use/cover change in the Yellow River Basin in recent 40 years were investigated by using Mann-Kendall and sliding t-test, geographic information TUPU standard deviation ellipse and gravity shift model. [Results] (1) From 1980 to 2021, forest land, shrub, water area, and construction land increased significantly, while the cultivated land, grassland, and wetland decreased significantly. (2) The periods of land use/cover change in the basin can be divided into 1980—1992, 1993—2001, 2002—2012, and 2013—2021, and the quantitative structure gradua
