我国城镇化转型正进入关键时期，城市化带来的一系列生态环境问题，高污染、高碳排放、缺乏生态功能的传统灰色雨水基础设施难以支撑城市生态建设。绿色雨水基础设施作为城市雨水系统的重要组成部分，对恢复与构建城市良性水循环、保护生态环境起着至关重要的作用。首先强调雨水、水循环与城市发展关系的重要意义，以此为基础，对绿色雨水基础设施的内涵、组成及基于绿色雨水基础设施构建城市良性水循环的水文学基本原理进行了简要阐述，提出以绿色雨水基础设施为基础构建可持续城市雨水系统，并结合实际案例说明绿色雨水基础设施规划设计的具体应用。%A series of eco-environmental problems have generated with the urbanization, which lead the urbanization reform in China into a critical period. While the conventional Grey Stormwater Infrastructure, which is pol ution intensive and ecological functions absent, fails to support the urban ecological construction, Green Stormwater Infrastructure, as the key part of urban drainage system, plays a vital role in restoring and establishing a healthy hydrological cycle and preserving the ecological environment. This paper states the significant relationship among rainwater, water cycle and urban development and gives a brief introduction on the concept and the composition of stormwater infrastructure, followed by a explanation of the hydrological principles of establishing a healthy urban hydrological cycle based on the Green Stormwater Intrastructure. It then puts forward the idea of establishing a Green Stormwater Infrastructure based sustainable urban stromwater system, and explains the applications of Green Stromwater Infrastructure Planning and Design with practical cases.
