上海里弄保护更新策略研究:类型价值、认知维度与技术路径

Study on Conservation Renewal Strategy of Shanghai Lilong:Type Value,Cognitive Dimension and Technological Path

作为上海近代最主要的居住社区与住宅类型,里弄是上海历史文化风貌区和风貌保护街坊的主要组成部分,也是上海近代城市风貌和居民生活记忆的重要载体。保护保留730万m2里弄是上海加强风貌保护、保障民生改善、推动城市更新的重要举措。通过对里弄类型的研究与多维价值的阐述,面对当下城市更新背景下里弄街区不断消亡、原真性破坏、绅士化与社会文脉断裂等主要挑战,结合主城区里弄保护等重点对象,开展系统理论研究、全面踏勘访谈与公众参与,尝试在产权视角下用动态发展的眼光看待当下里弄保护更新,提出里弄肌理保护更新的认知维度与基本原则、里弄建筑保护更新的考量维度与类型,以及里弄街区的功能延续、业态多样性与适应性策略,结合城市设计方法建立GIS数据平台,形成“一街坊一图册”,支撑管理部门保护更新政策的制定,以期为后续里弄保护更新提供思路与方法参考。

As the most important residential community and residential type in modern Shanghai,Lilong is the main component of historic and cultural districts and style protection neighborhoods in Shanghai.It is also an important carrier of Shanghai's modern cityscape and residents'living memory.The protection and preservation of 7.3 million m²of Lilongs is an important measure for Shanghai to strengthen the protection of style and features,ensure the improvement of people's livelihood and promote urban renewal.Based on the study of the type of Lilong and the multi-dimensional value statement and based on the main challenges in the context of the current urban renewal,such as Lilong neighborhoods'disappearance,destruction of authenticity,gentrification and rupture of social context,this paper conducts systematic theoretical research,comprehensive survey interviews and public participation,and tries to look at the current protection and renewal of Lilong from the perspective of property rights to put forward the cognitive dimensions and basic principles of conservation and renewal of Lilong texture,the dimensions and strategic types of conservation and renewal of Lilong buildings,and the functional continuity,the diversity of business forms and adaptive strategies of Lilong district.Based on the urban design method,the GIS data platform is established to form"one neighborhood,one atlas",which supports the formulation of protection and renewal policies.
