Scientifically evaluating the coordinated development of urban population agglomeration and land ecological resilience in the Yellow River Basin is crucial for promoting ecological protection and high-quality development in the region. Based on the “resistance-adaptability-resilience” three-dimensional framework, a land ecological resilience evaluation system was constructed. The coupling coordination model, Moran’s I, and spatial Tobit model were employed to analyze the spatiotemporal evolution, spatial agglomeration characteristics, and influencing factors of the coordinated development of urban population agglomeration and land ecological resilience in the Yellow River Basin from 2000 to 2023. The results indicate that: (1) The levels of urban population agglomeration and land ecological resilience exhibited a declining trend, with average annual decreases of 0.98% and 0.26%, respectively. The spatial distribution of urban population agglomeration followed a stepped pattern of “upstream>middle reaches>downstream”, while land ecological resilience was distributed as “downstream>upstream> middle reaches”. (2) The coordinated development level of urban population agglomeration and land ecological resilience declined over time, with a spatial distribution of “downstream>upstream>middle reaches”. High-value cities were primarily located in downstream areas and provincial capitals, remaining in the primary coordination stage, whereas low-value cities, predominantly resource-based, were on the verge of imbalance. (3) A spatial positive correlation was observed between urban population agglomeration and the coordinated development of land ecological resilience. “high-high” agglomeration areas were mainly concentrated in downstream regions and Sichuan Province, whereas “low-low” agglomeration areas were primarily located in the city group along the Yellow River Basin in Ningxia, Lanzhou-Xining city group, and Hohhot-Baotou-Ordos-Yulin city group. (4) Economic development, industrialization, scientific and technological innovation, and government intervention were key factors influencing the coordinated development of urban population agglomeration and land ecological resilience. Additionally, economic development and industrialization exhibited significant spatial spillover effects.
