英国蓝绿系统方法剖析及对我国海绵城市建设的启示

Analysis of the British Blue Green Solutions and Its Enlightenment to China Sponge City Construction

我国正处于城镇化快速发展时期,城市建设高速发展的同时面临着水环境污染、水安全缺乏保障、水资源紧缺、水生态被破坏等一系列问题。近年来,英国提出了蓝绿系统方法以解决城市环境问题,增强城市可持续性和韧性,这一方法强调以系统、量化的方式对城市水资源(蓝色系统)和城市植被系统(绿色系统)进行综合规划、设计、建设和管理,并鼓励利益相关者广泛参与规划设计过程。详细介绍了英国蓝绿系统方法包含的内容,同时,通过国内外案例来分别体现蓝绿系统方法的不同特点,旨在为我国海绵城市建设提供有效借鉴。案例表明,通过应用系统、量化的方法进行规划设计,蓝绿设施能获得很高的协同效益。

China is in the stage of rapid urbanization.The accelerating development of urban construction brings a series of problems,such as water environmental pollution,lack of water security,shortage of water resources and destruction of water ecology.To solve this kind of problems and enhance urban sustainability and resilience,in recent years,the UK proposed a Blue Green Solutions(BGSs).This approach emphasized the systematic and quantitative approach to the comprehensive planning,design,construction and management of the urban water resource(blue system)and the urban vegetation system(green system),and encouraged stakeholders to participate actively in this process.This paper introduced BGSs in detail,and exhibited domestic and foreign cases to reflect the different characteristics of BGSs,in order to provide effective reference for the sponge city construction in China.The cases showed that the blue green infrastructures could obtain high synergy benefit through systematic and quantitative planning and design.
