Against the background of global climate change and resource and environmental conflicts, the synergistic allocation of soil and water resources has become the research focus of regional sustainable development. Based on the CiteSpace bibliometric and visualization analysis tool, this paper systematically combs the literature development lineage and evolution trend of the research on water and soil resources allocation at home and abroad from 2000 to 2024. The results show that: (1) the hotness of water and land resource allocation research continues to rise, and domestic and foreign research shows the characteristics of “pioneer-catching up”; (2) the research hotspot focuses on “optimal allocation of water resources” “land use”, ‘agriculture’ and ‘watershed management’ and other topics, highly concentrated in the Yellow River Basin, the Three Rivers Plain and other key areas; (3) The focus of soil and water resource allocation has shifted from single resource allocation to coordination and integration between different systems; the research method has also gradually shifted from the previous static matching to the regulation method that can be adjusted dynamically, and the soil and water resource allocation is developing in the direction of system integration and intelligentization.
