摘要:
再生水的开发利用是解决城市水资源供需矛盾，实现节水的重要途径。对我国港澳台以外的31个省级行政区的城市再生水供需平衡关系进行计算，并通过聚类分析方法探究差异性分布规律，探讨城市再生水的最大供给潜力与再生水需求量之间的关系，进而为各类地区节水发展方向提供建议。不同地区按照城市再生水供需平衡关系分为4类：第1类地区大部分与我国典型的资源型缺水地区相吻合，再生水供需水平均较低；西藏自治区由于水资源禀赋优异和用水需求小的突出特征被单独分为第2类；第3类地区为沿海经济发达地区，再生水需求与供给潜力均为最高水平；第4类地区人均生活用水量相对较大，但缺少水资源总量优势，再生水需求和供给潜力均较可观。
Abstract:
The development and utilization of reclaimed water represent a crucial approach to resolving the supply-demand imbalance in urban water resources and achieving water conservation. This study calculates the supply-demand balance of urban reclaimed water across 31 provincial-level administrative regions in China excluding Hong Kong, Macao and Taiwan. Cluster analysis was then employed to investigate their differential distribution patterns. The relationship between the maximum potential supply of reclaimed water and its demand was examined to provide tailored recommendations for water conservation strategies in different types of regions. Based on the urban reclaimed water supply-demand balance, the regions were classified into four categories: Category 1 regions largely correspond to China’s typical resource-based water-scarce areas, characterized by a low capacity for domestic water supply. Category 2 uniquely comprises the Xizang Autonomous Region, which is distinguished by its abundant water resource endowment and low water demand. As economically developed coastal areas, category 3 regions are defined by a water use structure featuring a particularly high total demand for reclaimed water and supply potential. Category 4 regions exhibit relatively high per capita domestic water consumption despite limited total water resources, and demonstrate substantial demand and supply potential for reclaimed water.
