摘要
为了解中国南方丰水地区的用水结构,采用洛伦兹曲线和基尼系数,对惠州市各县(区)2013—2017年用水结构进行分析。结果表明,现状年(2017)农业用水和生活用水在惠州市内空间分布相对均衡,生态用水和工业用水在惠州市空间分布相对较为集中;从用水结构空间分布看,不同用水结构基尼系数未突破“警戒线”,但均呈现上升趋势,各区域用水差异性在逐步扩大,用水结构的空间均衡度有所下降。用水结构分析成果可为惠州市水资源管理及水资源合理配置提供技术支撑。
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.
