摘　　要：为探究湖北省用水结构演变规律,基于2003~2023年各类用水数据,采用信息墒、均衡度、洛伦兹曲线对用水结构演变进行分析。结果表明,在时间尺度上,2003~2023年湖北省用水量持续增长,用水结构信息墒和均衡度均呈上升趋势,近10年上升更快,各类用水整体趋向均衡。在空间尺度上,17个地级行政区的用水结构信息墒、均衡度存在较大差异,且发展趋势不尽相同。从洛伦兹曲线来看,农业用水空间分布较均匀,且相对稳定;工业用水空间分布在波动中趋向集中;生活用水空间分布差异呈增大趋势;生态用水空间分布差异最大,且变化较大。研究结果可为湖北省加强水资源管理与保护、增强人水和谐提供参考。In order to investigate the evolution of water use structure in Hubei Province,the information entropy,the equilibrium degree,and the Lorenz curve were used to analyze the evolution of water use structure based on the data from various types of water consumption between 2003 and 2023.The results show that on the time scale,the water consumption in Hubei Province increased continuously from 2003 to 2023,and the information entropy and equilibrium degree of the water use structure showed an upward trend;The upward trend was faster in the past 10 years,and the various types of water consumption tended to be balanced as a whole.On the spatial scale,there were significant differences in the information entropy and equilibrium degree of the water use structure across the 17 prefecture-level administrative regions,and the development trends was not the same.From the Lorenz curve,the spatial distribution of agricultural water was more uniform and relatively stable;The spatial distribution of industrial water tended to be concentrated in fluctuation;The difference in the spatial distribution of domestic water showed an increasing trend;The difference in the spatial distribution of ecological water was the largest and changed greatly.The results can provide a reference for strengthening water resource management and protection,as well as for promoting a better balance between human activities and water resources in Hubei Province.
