历史城镇肌理评价及保护性延续研究——以“黄河第一古镇”青城古镇为例

Study on Texture Evaluation and Preservative Continuity of Historic Towns——A Case Study of Qingcheng Ancient Town,the First Ancient Town on the Yellow River

青城古镇,一座文物遗产丰富、独具西北特色的历史性城镇,其200多年的历史也是兰州浓墨重彩的一笔。作为黄河兰州段特色村镇中的代表,青城古镇在肌理延续方面存在保护不当的问题。该文以青城镇为例,运用层次分析法,建立青城古镇肌理评价体系。同时运用GIS、空间句法等分析工具对古镇肌理进行分析,并从动态的角度评价肌理演变动因及延续情况,分析其影响因素,最后提出古镇肌理保护和延续的策略,从而促进古镇肌理更好地延续与发展。

Qingcheng ancient town,a historic town with rich cultural relics and unique northwest features,has a long history of more than 200 years and a renowned fame.As a representative of the special rural towns in the Lanzhou section of the Yellow River,Qingcheng ancient town has the problem of improper protection in the aspect of texture continuity.Taking Qingcheng Town as a case,this paper uses the analytic hierarchy process to establish a texture evaluation system for it.Meanwhile,analysis tools like GIS and spatial syntax are adopted to analyze the ancient town's texture,evaluate the motivation of the texture evolution and the continuity situation from a dynamic point of view,and analyze the influencing factors,with strategies for the preservative continuity of the ancient town"s texture proposed,thereby better promoting the continuity and development of the ancient town,s texture.
