历史地区城市更新中的话语、理念与制度

The Discourse,Concept,and Institution in Historic Area Regeneration

在借鉴话语制度主义方法的基础上,提出一个分析历史地区城市更新的理论框架,讨论历史地区城市更新中作为范式的理念、技术型理念和作为公众情绪的理念。基于案例讨论,提出“旧城改造”作为范式的理念主导了历史地区城市更新中的问题界定,并基于此建立了具体的更新制度;“历史(风貌)保护”作为范式的理念的研究则仍停留在技术层面的讨论。在此基础上,分析技术型理念层面的具体制度,认为土地收储、规划管控和建设管理等3类制度在运作时呈现出时空分离、自我演进、互相加强的特征,虽然共同支撑了“旧城改造”作为范式的理念发挥作用,但是也阻碍了新范式理念的落实。由此,基于话语制度主义方法,提出在历史地区城市更新中需要推进范式理念的转变和技术型理念的革新,并将历史文化保护作为“公众事业”来推动。

A theoretical framework for analyzing the urban regeneration in historic areas based on the discourse institutionalism approach is proposed.This framework reveals the interrelationship among the paradigm ideas,technical ideas,and ideas as public sentiments.First,by applying this framework in the case study,the concept of"old city reconstruction"as a paradigm has led to the definition of problems in the urban renewal of historical areas,and based on this specific renewal system is established.In contrast,the"historic conservation"as a competitive discourse remains at the technical level.Secondly,by exploring the specific institutions in regeneration,the institutions affecting historic areas'regeneration into three core institution clusters are classified:land expropriation,planning regulations,and construction management;then that these three institution clusters are spatialtemporal separating,self-evolving,and mutually reinforcing are proposed.Moreover,these three institution clusters constitute a"conventional mode",making it difficult to implement new paradigm ideas.Finally,it is necessary to promote the transformation of paradigm ideas and the innovation of technical ideas and promote historic heritage conservation as a collective enterprise.
