基于城市历史格局分析的文化空间叙事性重构——米脂古城保护规划中的探索

Narrative Reconstruction of Cultural Space through Historic Analysis of Urban Pattern:A Case Study of Mizhi

历史城区保护面临两大问题:一是缺乏全面系统的策略,二是保护本身无法为历史城区的存续提供合理性依据。然而在现有理论方法框架内,上述二者难以同时解决。鉴于此,本文通过总结米脂古城保护规划实践的相关经验,提出"文化空间叙事性重构"策略,即将历史城区看作一份"叙事文本",从"边界、路径、区域、节点、标志物"等几大要素切入,分析其历史格局,追溯其变迁辙迹,并以此为依据,从空间尺度、城市肌理、文化传统等方面着手重构古城作为一个完整文化空间所应具有的维度。该保护策略能够实现对历史城区在时空二重尺度上的全面、系统性保护,同时又令其赖以生存的历史土壤得以还原,从而获得在现代社会中的"存在合理性"。

The conservation of historic cities faces two problems： 1 ） One is the lacking of a comprehensive and systematic strategy for conservation ; 2 ） the other is that conservation itself cannot establish a rational basis for the existence of historic cities. There is no such a solution that can deal with them both simultaneously within the current theoretical framework. Therefore, based on the practice applied in the Conservation Planning of Mizhi, the paper proposes a strategy for ＂Narrative Reconstruction of Cultural Space＂, which means, firstly, treat historic cities as ＂Narrative texts＂, analyze the urban pat- terns in history and the routes of vicissitudes by checking five factors ： Path, Edge, District, Node and Landmark. Then re- construct the dimensions of cultural spaces through spacial scale, urban texture and cultural tradition. This strategy will lead a comprehensive and systematic conservation, and this will revive the historic urban environments.
