摘要
研究表明,城市的形态和结构具有分形性质,复杂的分形结构提高了历史空间的稳定性,有利于激发历史空间的活力。本文以波兰历史城市克拉科夫为研究对象,对古城历史空间的分形结构与分形特征进行解析。其中包括了两个研究层次:其一,以克拉科夫古城为样本进行历史原型分析,通过分形元与分形秩序,解析古城的分形特征,提取分形结构中具有优越性的分形元素与设计方法;其二,以克拉科夫卡齐米日旧城区复兴为例,从多层级叠合、小尺度连接、多功能混合、各时段叠加四个方面,通过层次化增加不同尺度上的结构,形成在所有尺度上均丰富而复杂的城市肌理,从而激发旧城区的活力。基于分形理论的城市历史空间修补可为其他历史城市所借鉴,尤其对我国的"城市双修"有重要的启示作用。
It is indicated that forms and structures of cities have the properties and characteristics of fractal structures.The complex fractal structure improves the stability of historical space and stimulates the vitality of historical space.Therefore,this paper takes Krakow as the study object,which is a historic city in Poland,to analyze the fractal structure and characteristics of historic space in the ancient city.It includes two research levels.(1)Taking Krakow as the sample to carry on the historical prototype analysis,and analyze the fractal characteristics of the ancient city based on fractal elements and fractal order,to extract the fractal elements and design method which has the superiority in the fractal structure.(2)In order to stimulate the vitality of the old urban area,it takes the revitalization district of Krakow-Kazimierz as an example to make analogy research of the historical prototype from four aspects,such as multilevel superposition,small-scale connection,multi-function mixing and time stack.The rehabilitation of urban historical space based on fractal theory can be used by other historical cities.Especially,it has an important inspiration for city betterment and ecological restoration in China.
