城市化作为对下垫面条件的主要影响因素之一,对水文循环的整个产生过程有很大的影响。本文以城市化进程对水文的影响为切入点,探讨城市化对水文(包括降雨、径流、水资源和水环境四个方面)的影响,从而促进流域城市绿色基础设施的规划与构建以及全流域的经济、社会和环境三位一体的可持续发展。为进行合理的城市防洪和排水系统的水利工程规划与设计提供支持,以促进城市更好的发展,具有很重要的现实意义。 Urbanization, as one of the main influencing factors on underlying surface conditions, has a great influence on the whole process of hydrological cycle. In this paper, the impact of urbanization process on hydrology is explored, and the impacts of urbanization on hydrology (including rainfall, runoff, water resources and water environment) are discussed to promote the planning and construction of urban green infrastructure and the whole basin Economic, social and environmental Trinity of sustainable development. It is of great practical significance to provide support for rational planning and design of water conservancy projects in urban flood control and drainage systems to promote better urban development.
