摘　　要：江苏省13个地市的社会经济发展水平、水资源禀赋、用水效率、节水水平等条件差异明显,节水模式与推进路径不尽相同。在充分吸纳现有用水效率指标的基础上,从水资源状况、社会经济条件、节水、供水、用水和排水等6个方面构建具有江苏特色的节水分区指标体系。引入主成分分析+系统聚类方法,划分了3个节水分区:Ⅰ区包括南京市、常州市、无锡市和苏州市;Ⅱ区包括淮安市、盐城市、扬州市、泰州市、南通市和镇江市;Ⅲ区包括徐州市、连云港市和宿迁市。在各区节水工作现状分析的基础上总结各分区的节水工作重点。本研究可为探索丰水地区节水优先途径等后续工作提供支撑。The level of economic and social development,water resource endowment,water use efficiency and water saving of 13 cities in Jiangsu Province are quite different,the mode and promotion path of water saving differ from each other.Based on the existing indicators,this study team constructed a water saving zoning index system with Jiangsu characteristics in six aspects:water supply,water saving,water use,drainage,water resources and socioeconomic conditions.Then,the “principal component analysis + systematic clustering” method was introduced and divided into three water-saving zones:Zone Ⅰ includes Nanjing,Changzhou,Wuxi and Suzhou;Zone Ⅱ includes Huai'an,Yancheng,Yangzhou,Taizhou,Nantong and Zhenjiang;Zone Ⅲ includes Xuzhou,Lianyungang and Suqian.Finally,based on the analysis of current water saving status in each zone,the key emphasis in water saving work was proposed.The water-saving divisions of Jiangsu Province in this study can provide important support for exploring water-saving priority approaches in regions with abundant water.
