The Yellow River Basin is ecologically fragile, the relationship between water and sand is unbalanced and water resources are scarce. This paper takes the urban agglomerations in the Yellow River Basin as the research object, based on the guidelines for the coordinated promotion of ecological protection and high-quality development in the basin, and uses the entropy weight method and the coefficient of variation method as the means to establish a quantitative evaluation system for coordinated development. The degree of synergy is between ecological protection and high-quality development of the urban agglomerations from the time dimension and the space dimension, and we give the optimization directions. The results show that the degree of synergy among urban agglomerations in the river basin is steadily increasing, but there are significant spatial differences in the degree of coordination of ecological protection and high-quality development of the urban agglomerations and the development index of its subsystems. The degree of synergy generally presents a cascade distribution pattern that gradually decreases from east to west and from downstream to upstream. The ecological destruction, economic fluctuations and water waste of the river basin urban agglomeration are the main factors hindering the improvement of synergy.
