基于空间形态算法的北京老城区道路网络演变

The evolution of Beijing city road network based on spatial morphology

北京老城区的道路格局自元代形成雏形,明清时期道路的数量逐渐增加,形成稳定格局。经历民国时期的动荡,新中国成立后的调整和城市发展的影响,老城区道路的数量和格局发生变化。然而,老城区传统道路格局保护和更新是北京市历史文化名城建设的重要内容。因此,本文基于空间形态分析算法,利用地理信息系统(GIS)和Matlab等软件,对重要历史节点的道路格局包括路名、路网密度、道路方向、用途等内容进行了定量研究。为北京市老城传统道路格局保护、道路历史变迁研究提供参考。本文采用的定量化研究方法也为老城传统格局研究提供了新方法。

The pattern of Hutong in the old urban area of Beijing has taken shape since the Yuan Dynasty and gradually increased in the Ming and Qing Dynasties,forming a stable pattern.After the turbulence in the period of the Republic of China,the adjustment after the founding of the People's Republic of China and the influence of urban development,the number and pattern of traditional hutongs in the old urban area have changed.However,the protection and renewal of traditional hutongs in the old urban area is an important part of the establishment of Beijing's famous historical and cultural city and the key object of urban renewal action.Therefore,based on the spatial morphological analysis algorithm and using geographic information system(GIS)and MATLAB software,this paper made a quantitative study on the Hutong pattern of important historical nodes,including road name,road network density,road direction,use and so on.The quantitative method also provided a new idea for the study of the traditional pattern of the old city.
