城市化是经济发展的潜在因素，经济发展是发展社会的主要途径。随着城市化规模的扩大，城市水环境的质量可能发生恶化，并对城市化的可持续性产生负面影响。因此，必须全面了解城市水环境的功能，包括安全、资源、生态、景观、文化和经济等方面。此外，有必要对城市水环境的理论基础进行深入分析，这一基础与景观生态和低碳经济相关。本文阐述了构建城市水环境系统的主要原则（包括可持续发展、生态优先和区域差异），并提出了城市水环境系统的内容。此系统包括自然水环境、经济水环境和社会水环境。其中，自然水环境是基础，高效的经济水环境是中心，健康的社会水环境是本质。建设城市水环境离不开综合安全体系、完整的科学理论和先进的技术。

Urbanization is a potential factor in economic development, which is a main route to social development. As the scale of urbanization expands, the quality of the urban water environment may deteriorate, which can have a negative impact on sustainable urbanization. Therefore, a comprehensive understanding of the functions of the urban water environment is necessary, including its security, resources, ecology, landscape, culture, and economy. Furthermore, a deep analysis is required of the theoretical basis of the urban water environment, which is associated with geographical location, landscape ecology, and a low-carbon economy. In this paper, we expound the main principles for constructing a system for the urban water environment (including sustainable development, ecological priority, and regional differences), and suggest the content of an urban water environmental system. Such a system contains a natural water environment, an economic water environment, and a social water environment. The natural water environment is the base, an effective economic water environment is the focus, and a healthy social water environment is the essence of such a system. The construction of an urban water environment should rely on a comprehensive security system, complete scientific theory, and advanced technology.
