基于不同人群话语分析的城市历史景观层积机制研究——以襄阳为例

人对城市风景的感知与理解,推动了城市历史景观的层积过程。基于不同人群话语分析,以元素类别和空间类型2种分类方式构建相对系统、科学的城市历史景观层积识别框架,探讨城市历史景观的动态演变机制。以明清时期襄阳为例,分政府和文人2类话语组对历史书籍、诗文的语汇逻辑、情感倾向进行统计分析,设置等里数同心圆坐标,以古城物理中心位置为圆心,标记元素空间点位。厘清作为主动因的话语作用于城市历史景观各元素及空间类别并最终实现文化层积的全过程,梳理出明清时期襄阳城市历史景观层积机制和基础框架,以期推动城市历史景观保护与发展,为襄阳的保护实践提供参考。

The Layering Mechanism of Historic Urban Landscape Based on Discourse Analysis of Different Populations: A Case Study of Xiangyang

People''s perception and understanding of urban landscape promotes the layering process of historic urban landscape (HUL). Based on discourse analysis of different populations, a relatively systematic and scientific identification framework of HUL layering is constructed with two classification methods of element and space types, and the dynamic evolution mechanism of HUL is explored. Xiangyang in the Ming and Qing Dynasties is selected as the research case. It is divided into official and literati discourse groups to conduct statistical analysis on the vocabulary logic and emotional tendency of historical books and poems. A concentric circle coordinate in li (Chinese ancient unit of length) is set. It takes the physical center of the ancient city as the center to mark the element space point. As the main motivation, the discourse acts on the various elements and spatial categories of the HUL and finally realizes the whole process of cultural stratification is clarified. On this basis, the layering mechanism and basic framework of the HUL of Xiangyang during the Ming and Qing Dynasties are sorted out in order to promote the protection and development of the HUL and provide a reference for the protection practice of Xiangyang.
