城市灰绿两色基础设施整合下的大型公共空间建设——从波士顿经验到当代实践

摘要

灰绿两色基础设施是建设大型城市公共空间的重要资源.基于城市设计视角,从空间组织结构与使用方式2个方面,对美国波士顿“祖母绿项链”、查尔斯河滨大道公园,以及“大开挖”中央隧道改造工程3个典型案例进行比较分析与解读,探索基于两色基础设施整合建设大型公共空间的设计策略,以及基于两色基础设施整合的大型公共空间在城市中的功能与效用,总结其经验,并结合当代实践,为中国城市存量建设中大型公共空间资源的挖掘与利用提供理论与实践层面的参考.%Grey and green infrastructure are important resources for constructing public space in cities."Emerald Necklace",Charles River Park and "Big Dig" are analyzed from the aspects of space structure and ways of use from the perspective of urban design,in order to find the strategy of constructing large-scale public spaces on the basis of grey and green infrastructure,as well as the function of largescale public spaces based on grey and green infrastructure.Experience is summarized as a theoretical and practical reference for public space exploitation and development in China.
