城市绿色雨水基础设施研究——以美国绿色街道为例

Urban Green Stormwater Infrastructure:Case Studies of Green Streets from Portland,New York,and Chicago

城市建成区不透水表面加剧了城市内涝和水污染等环境问题。作为绿色雨水基础设施类型之一的绿色街道是解决此类问题的高效手段,也是美国近年来可持续城市发展的重点方向。绿色街道还具有提升城市环境、社会和经济等多方面效益。波特兰、纽约市和芝加哥很早便开始探索建设绿色街道,目前已形成了较为完善的技术体系、建设模式和管理机制。该文分析和归纳了三座城市绿色街道在布局形式、植物配置和管理维护方面的经验与不足,以期为我国绿色雨水基础设施建设与城市微更新提供参考。

The impermeable surface of urban built-up areas has exacerbated environmental problems such as urban waterlogging and water pollution.As one of the types of green stormwater infrastructure,green street is an efficient means to solve such problems,and it is also the key direction of sustainable urban development in the United States in recent years.Green street also can help improve the environmental,social and economic benefits of cities.Portland,New York City and Chicago started to explore the construction of green streets a long time ago,and have formed relatively complete technical system,construction mode and management mechanism.We analyzed and summarized the experience and deficiency of green streets in terms of layout form,plant configuration and management and maintenance in three cities,in order to provide reference for our country's green stormwater infrastructure construction and urban micro-renewal.
