城市历史景观“锚固——层积”解构与可视化评估——以松溪县为例

Visualization Assessment and Deconstruction of"Anchor-Layers"in Urban Historic Landscape:A Case Study of Songxi County

该文探讨了城市历史景观(HUL)中“历时性”和“共时性”的理念和方法在城市历史文化层积解译中的指导作用。基于“锚固—层积”理论识别历史环境的时空层积变化特征,解构历史层积,通过GIS及空间句法理论对历史层积要素进行转译及可视化评估,从而梳理层积状态及层积要素类型。最后该文以千年古县松溪为例,从挖掘城市历史文化的历时性特征、评估历史层积的共时性价值两方面,探索历史环境与城市化相契合的保护策略。

In this paper we explore the guiding role of the concepts and methods of"diachrony"and"synchronism"in the Historic Urban Landscape(HUL)in the interpretation of urban historical and cultural layering.Based on the theory of"anchoring-layering,"we recognize the spatial and temporal layering characteristics of the historical environment and deconstruct the historical layering.Through GIS and space syntax theory,the elements of historic layering are translated and visualized to sort out the state of layering and the types of layering elements.Taking Songxi,a thousand-year-old county,as a case study,we explore the conservation strategy that fits the historical environment and urbanization from the aspects of excavating the diachrony features of urban history and culture and evaluating the synchronism value of historical layering.
