基于分形理论的赤水河中下游传统古镇街巷空间地界面形态研究

Study on the Spatial Interface Morphology of Streets and Alleys in Traditional Ancient Towns in the Middle and Lower Reaches of Chishui River based on Fractal Theory

随着城镇化进程的推进,传统古镇日趋衰落,如何保护和延续其独特的街巷空间形态已引起广泛关注。地界面作为构成传统古镇整体形态肌理的“骨架”,记录了古镇的历史发展、文化传承以及居民的生活记忆。然而,经过长期的局部更新,古镇街巷空间地界面的尺度失去了控制,致使街巷空间形态的识别率逐渐降低。鉴于传统古镇街巷空间的复杂性和地域性,文章基于分形理论的方法,结合数理统计学对古镇街巷空间地界面的形态特征和演变规律进行量化解析,研究所得的分析结果和量化指标可为传统古镇街巷空间地界面形态的保护提供数据支撑和判断依据。

With the advancement of urbanization,traditional ancient towns are gradually declining,and how to protect and continue their unique spatial form of streets and alleys has attracted widespread attention.The spatial forms of streets and alleys in traditional ancient towns have their own characteristics due to regional environmental differences,recording the historical development,cultural inheritance,and residents'life memories of the ancient town.However,long-term local renovations and updates have led to a gradual decrease in the recognition of the streets and alleys in the ancient town.In view of the complexity and regionality of the spatial morphology of the streets and alleys in traditional ancient towns,this paper takes the spatial morphology of the streets and alleys in traditional ancient towns in the middle and lower reaches of the Chishui River as the research object,and uses the fractal geometry theory and mathematical statistics methods to quantitatively analyze the morphological characteristics and evolution laws of the spatial interface of the streets and alleys in ancient towns,the analytical data and quantitative indicators obtained from the research can provide data support and judgment basis for the protection and updating of the spatial form of traditional ancient towns'streets and alleys.
