面向提升新城活力的步行系统规划策略研究——以上海市嘉定新城中心区为例

摘要

新城活力问题是中国后半程城市化阶段所要面临的一项重要挑战.首先介绍了国际上哥本哈根、纽约、墨尔本、巴黎等地通过公共空间改造实现城市复兴的成功经验.其次,以上海市嘉定新城中心区为例,分析了现状城市活力不足问题的成因,并从步行系统规划角度出发探讨提出了提升城市活力的若干策略和方法,包括构建可识别的步行环路、打造新城地铁站门户广场、激活封闭小区周边的街道界面、重视开放街区内部道路环境品质、增设日常活动公共空间节点等.%The problem of vitality in new towns becomes a critical challenge that China will face in her second-half stage of urbanization. This paper first introduces the successful experience of city revitalization through public space redevelopment in Copenhagen, NewYork, Melbourne and Paris. Then taking the central Jiading new town as an example, this paper analyzes why the city is lack of urban vitality. From the perspective of pedes-trian system planning, a number of strategies for enhancing vitality are proposed, including constructing recognizable walking circuits, creating metro station gateway plazas, activating street facade around the gated communities, improving internal street environment within open blocks, and designing public space nodes for daily activities.
