基于可持续“3E”视角的城市设计策略思考——以街道空间为例

REFLECTION ON URBAN DESIGN STRATEGIES BASED ON 3ES OF SUSTAINABLE DEVELOPMENT:TAKING STREET SPACE FOR EXAMPLE

随着环境问题日益严峻,对生态和绿色城市设计的呼声与日俱增,但从综合城市可持续发展角度对城市设计策略的分析尚缺。本文以街道空间为切入点展开对可持续设计策略的研究,首先回顾可持续城市设计理念的演变历程,归纳其在空间扩张、社会运动、经济增长和环境保护等方面的思想转变。在此基础上,借用可持续发展的"环境—社会—经济"三支柱要素体系,构建可持续城市设计策略"场所(环境)—使用者(社会)—全周期(经济)"三位一体的要素分析框架。进而结合国际案例,以绿色基础设施、公共交通优先、开放空间共享和城市安全再造为例,对可持续街道空间设计策略的应用加以分析。

With the increasing of environmental problems, the call for ecological and green urban design is increasing day by day. But the analysis of urban design strategy from the perspective of sustainable urban development is still lacking. In this paper, the study of sustainable design strategies is carried out with street space as the starting point. Firstly, the evolution of sustainable urban design concept is reviewed, and the idea changes in spatial expansion, social movement, economic growth and environmental protection are summarized. On this basis, the paper is aimed to construct a sustainable urban design strategy by using the three pillar elements system of ＂environment, society and economy＂ of sustainable development, and constructing trinity element analysis frame of ＂Location（environment）, user（society） and full- cycle（economy）＂. And then combining with international cases, the application of sustainable street space design strategy is analyzed with green infrastructure, public transport priority, open space sharing and urban safety recreating.
