中文摘要：

在总结区域水资源承载力的研究基础上。以城市化地区为重点从水循环过程出发．探讨高强度人类活动影响下水资源的形成和转化规律．分析水资源承载力的内涵．探讨城市化地区水资源承载力的理论研究基础，即：变化环境下的水循环理论、城市化与“社会经济-水资源-生态与环境”系统交互胁迫理论和可持续发展理论。并在可持续发展原则指导下．提出城市化地区水资源承载力量化研究的理论框架和方法．将城市化地区水资源承载力的研究纳入到区域“社会经济-水资源-生态与环境”复合系统中，从水循环动力过程出发。揭示水资源承载力的本质。研究成果可为城市化地区节水战略的实施、水资源合理配置和社会经济的可持续发展提供理论支撑。

英文摘要：

Based on regional water resource carrying capacity research, this article took urbanized areas as a research object and began from water cycle process in the urbanized area to discuss water resource transform process that is influenced by intensive humanity activity and to analyze water resource carrying capacity connotation of urbanization area. The basic theories were proposed for water resources carrying capacity research in urbanized area, namely： the water cycle theory under changing environment, the interaction theory between urbanization, and the ＂social economy-water resources-ecological environment＂ composite system and sustainable development theory. Moreover, under the sustainable development principle, we brought the urbanized area water resource carrying capacity research into the complicated system of region ＂ social economy - water resources - ecology and environment＂, and analyzed the coordinated relationship among water resources, social economy development, and ecological and environmental protection. We also proposed the theory frame and the method of water resources carrying capacity quantification research in urbanized areas. The research results may provide a theory support for implementation of water saving strategy, water resource reasonable disposition and sustainable development in urbanized areas..
