The Yellow River Basin is the implementation area of ecological protection and high-quality development strategy. The evaluation of available land resources is of great significance to the territorial and spatial planning and high-quality development in the Yellow River Basin. Based on the remote sensing data from 1990 to 2020 extracting land use data, DEM and slope information, using reserve available land resource evaluation method, exploring the temporal and spatial evolution trend of reserve available land resources along the Yellow River in Jinan City during the past 30 years, analyzing the regional orientation of the use of reserve land resources in different regions. The results indicate that:(1)the reserve suitable construction land area in Jinan City was 292.48 km2 and was decreasing and mostly in the southern part of the study area, among which Licheng District and Changqing District had the highest reserve construction land potential, and the area of reserved construction land in Tianqiao, Licheng, and Shizhong Districts had significantly changed, the area change was 13.97 km2, -13.84 km2, -9.66 km2, respectively;(2)Jinan City had the large potential of reserved cultivated land(360.67 km2), and the spatial distribution pattern was similar to the reserved construction land; the changing magnitude decreased in the order: Licheng, Tianqiao, Shizhong, Changqing, Huaiyin, and Lixia Districts, among which Licheng and Changqing Districts had the highest reserve cultivated land potential;(3)based on the overlap and differences of the two types of land, and regional socio-economic development and natural environmental conditions, it can be seen that the reserve land resources in the southern Tianqiao District, Changqing District and northern Huaiyin District, Shizhong District, and Lixia District of Jinan City can be converted into construction land, and the reserve land resources in the central and southern parts of Licheng District and the central and southeastern parts of Changqing District can be converted into new cultivated land.
