Abstract: In order to scientifically recognize the current situation and spatial distribution characteristics of China"s spatial equilibrium of water resources, a spatial equilibrium of water resources evaluation system was constructed based on the analysis of the connotation for spatial equilibrium in water resources. Using 333 prefecture-level cities and 4 municipalities directly under the central government in China as the study objects, the spatial equilibrium state of water resources in each region of the country was measured and spatial correlation analysis was conducted. The results show that the spatial equilibrium state of each province is characterized by large spatial differences. Among the 31 provincial administrative regions in China, a total of 17 provinces are in a state of spatial imbalance, and the regions with poor spatial equilibrium are mainly located in the three eastern provinces, the North China Plain, the Hexi Corridor, parts of southern China and southern Xinjiang. There is a certain degree of aggregation in the spatial equilibrium of each study unit, which is mainly in two patterns of high value aggregation and low value aggregation, and also scattered with a small range of low-high aggregation and high-low aggregation patterns. The research results provide scientific reference for taking effective measures to promote spatial equilibrium of water resources.
