[Objective]This study aims to understand the characteristics and influencing factors of the evolution of the hydroecological spatial pattern in the upper, middle and lower reaches of the Yellow River Basin, to promote the integration of water resources use regulation into the territorial spatial planning system, and to enhance ecological protection and high-quality development in the Yellow River Basin. [Methods]Spatial transition matrices and optimal geographic detectors, among other quantitative models, were used to analyze regional differences in the evolution of the hydroecological spatial pattern across the upper, middle and lower reaches of the Yellow River Basin. This analysis delineated the paths of spatial pattern evolution and revealed the underlying influencing factors. [Results](1)The scale of the hydroecological space in the Yellow River Basin was 27 600 km2, accounting for only 2.28% of total land area in the basin, with the proportions in the upper, middle and lower reaches being 22:2:3. During the study period, there was an expansion of 4 989.90 km2, with the largest growth in the upper reaches and the most drastic increase in the lower reaches.(2)In the upper reaches, the hydroecological space transformation involved interactions with other ecological spaces, leading to a large-scale expansion of hydroecological space, followed by a minor loss due to interactions with agricultural space. In the middle reaches, the main transformations occurred with agricultural spaces, leading to a small-scale expansion of hydroecological space. In the lower reaches, the conversion of agricultural space into hydroecological space led to a large-scale expansion, while hydroecological space also was converted into urban space on a large scale.(3)The core factor influencing the massive expansion of hydroecological space in the upper reaches was the ‘liquefaction' of water resources in the hydrological cycle, with losses mainly driven by the demands of primary and tertiary industries. In the middle reaches, the evolution of the hydroecological space pattern was predominantly governed by governmental fiscal policies adapted to local natural geographical conditions and socio-economic development. In the lower reaches, the changes in hydroecological space were associated with urbanization processes, shifting between agricultural and urban areas. [Conclusion]The characteristics, pathways, and influencing factors of the evolution of hydroecological spatial patterns in the upper, middle and lower reaches of the Yellow River Basin are significantly different. It is necessary to establish a river basin collaboration system for joint governance and coordinated development based on the developmental positioning of water resource protection and utilization in each region.
