摘　　要：以云南省滇中受水区2009年~2018年的用水数据为基础,运用熵理论、洛伦兹曲线和改进的基尼系数等方法对该受水地区的用水结构的时空演变态势进行分析。结果表明,从时间尺度上看,受水区中昆明市的用水结构稳定,各类型用水发展均衡;玉溪紧随其后,最具发展潜力的是红河州;但各分区差异性较大,尤其是生态用水,最大差距可达56倍。从空间尺度上看,各分区农业、工业、生态用水基尼系数都有不同程度的下降,其中生态用水基尼系数下降幅度达0.505,说明生态环境保护得到重视;但2018年生态用水基尼系数仍表明各分区生态用水差异性大,处于不均衡的状态。整体看,受水区用水结构的时空演变态势都朝着好的方向发展。Based on the water consumption data of the central Yunnan water receiving area from 2009 to 2018,the entropy theory,Lorentz curve and improved Gini coefficient are used to analyze the temporal and spatial evolution of water use structure in the central Yunnan water receiving area.The results show that,in terms of time scale,the water use structure of Kunming City in water receiving area is stable and the development of various types of water use is balanced,followed by Yuxi,and Honghe Prefecture has the most development potential,but there are large differences between each sub-region,especially for ecological water use,the maximum gap can reach 56 times.From the perspective of spatial scale,the Gini coefficients of agricultural,industrial and ecological water use in each sub-region have declined to varying degrees.Among them,the Gini coefficient of ecological water consumption has decreased by 0.505,indicating that the ecological environmental protection has been paid attention to,but the Gini coefficients of ecological water in 2018 still shows that the ecological water use in each sub-region is very different and in an unbalanced state.From an overall point of view,the temporal and spatial evolution of water use structure in the water receiving area is developing in a good direction.
