摘要:闲述了区城用水量内涵及其影响因素分析方法,把区城用水量影响归纳为区城经济发展驱动和水资源案赋约束两方面;根据聚类线性归计算原理,建立了区成用水量影响因素分析模型及其计算方法步豫。针对太湖流城的水资源利用影响因素,从人口规模、生产总值、产业结构等方面入手,利用聚类线性回归模型对太湖流城区城用水量的影响固素进行评价研究:从相关分析看,区城经济发展的用水则性需求是太湖流域区城用水量的主要驱动因素,区城产业结构对太湖流城的用水形成显著的抑制效应;而在水资源案赋约束方面,太潮流受
水资源短缺胁追较小,区域用水量还存在增长的空间。关键词:区城;用水量;影响固素;聚类线性园归

Abstract: The connotation of regional water resources utilization and its influencing factors are described and analyzed, and the regional economic development driving and water resources endowment restricting are generalized as two aspects in influencing factors of regional water resources utilization, Clusterwise linear regression model is introducted and described, furthermore the influencing factors of regional water resources utilization of Taihu basin area are analyzed, Some factors are selected such as population proportion, GDP, industrial structure etc, and clusterwise linear regression method is applied to evaluate and research influencing factors of regional water resources utilization. According to the analysis, there is a result that the dominant factor of Taihu basin water resources utilization is that water resources rigid requirements of regional eco-nomic development. Additionally, industrial structure on the Taihu Basin bring about inhibited effect in utilization of water resources. For the water resources endowment restricting, the water resources shortage stress of Taihu basin is comparative-ly low,there until is elimbing space of water resources utilization.
Key words: regional;water resources utilization;influencing factors;clusterwise linear regression

注。节水型社会建设、从供水管理为主转向需水管理为主的水资源管理模式的确立,都将社会水循环原理与调控作为其重要的科学基础之一。区域用水量的研究是社会水循环中的关键环节,区域用水量的渐变机制以及各类用水主体、经济产业规模和结构调整的共同作用造就了其自身通量的涨落与变化。在当前最严格水资源管理制度的背景下,区域用水量研究为解释不同地区的社会水循环的演化方
