In order to understand the water utilization structure of water-rich areas in southern China, this paper analyzes the water utilization structure of counties (districts) in Huizhou from 2013 to 2017 by using Lorenz curve and Gini coefficient. The results show that in the current year (2017), the spatial distribution of agricultural water and domestic water in Huizhou is relatively balanced, while that of ecological water and industrial water is relatively concentrated. From the perspective of spatial distribution of water utilization structure, the Gini coefficients of different water structures do not exceed the “warning line”, but they all show an upward trend. The difference of regional water use is gradually expanding, and the spatial balance of water utilization structure declined, which can provide technical support for the management and rational allocation of water resources in Huizhou.
