城市遗产保护视野中的北京大栅栏街区

Perspective of Urban Heritage Protection on Dazhalan Block,Beijing City

大栅栏街位于明清北京古城内,是体现北京城区街巷胡同传统风貌的重要街区之一。斜街肌理是大栅栏街区特色之一。在对大栅栏街区街巷胡同及其传统建筑遗存率的节点调研与主街调研的基础上,本文认为(:1)今天大栅栏街区较高的传统风貌率是以大量拆除传统建筑与大量建造仿古建筑为代价的;(2)大栅栏街区历史传统风貌的核心保护区,宜确定为"大栅栏历史文化保护区"与"东琉璃厂历史文化保护区";(3)大栅栏街区的斜街肌理与30%的传统建筑遗存率是衡量大栅栏街区历史传统风貌保护状况的两个指标。

Located in the downtown of Beijing,Dazhalan Block is one of those important blocks reflecting the traditional style of streets and lanes in Beijing.The twilldirection lane texture is one of characteristics in the Block.Depending on the analysis of streets and lanes as well as traditional architecture in the area,this paper points out that：（1）the high traditional style rate in present Dazhalan Block is at the cost of demolishment of many traditional houses and construction lots of new imitating-tradition buildings;（2）the core protected area of historic landscape in Dazhalan Block should be＂Dazhalan Historic Protected Areat＂and ＂East Liulichang Historic Protected Area＂;（3）there are two key indexes,twill-direction lane texture and 30% perception of remained historic buildings,for measuring the protection of historic landscape in Dazhalan Block.
