A Study On The Urban Spatial Forms Along The Railway Corridor In The Central Area Of Beijing

China is a major railway country.Railway is not only an economic artery,but also witnesses the prosperity and decline of cities along the route and the development and changes of urban space.With the development of the city,due to the separation of urban space and land along the railway line,there has been a mess along the line.Under the premise of high-quality urban development,the space along the railway is an urgently needed ground transportation space.Among the many railway corridors in Beijing,the Beijing-Zhangjiakou Railway has an important historical position and represents a typical urban spatial morphology change process.Therefore,the thesis takes the railway corridors in the central city of Beijing as the pre-research object,constructs the urban morphological evolution model based on the theory of morphological typology,and then takes the Beijing-Zhangjiakou Railway as an example for in-depth analysis.After studying the related theories of urban space morphology,and learning from the classification method of morphological typology on the elements of urban space morphology,the urban space morphology elements are divided into two parts: plane pattern and building type.According to the secondary relationship of each space element,the plane layout is divided into three parts: street system,plot combination and land use nature;the building types are divided into: building type,building form,and building height.After determining the urban spatial morphology research elements,according to the current situation of the urban space along the railway corridor in the central area of Beijing,a model suitable for the evolution of the urban spatial morphology along the railway corridor in the central area of Beijing was constructed.This model is used to conduct an in-depth study of the urban space along the Beijing-Zhangjiakou Railway Traffic Corridor.Based on the research on the urban spatial morphology elements along the Beijing-Zhangjiakou Railway Corridor,the law of urban spatial morphology evolution along the Beijing-Zhangjiakou Railway is summarized.According to the law of evolution,the evolution of urban space is discussed from three aspects: economic development,planning policies,and major events.Cause.In order to realize the high-quality development of transportation space,it provides data reference while enriching the spatial data and materials of the Beijing-Zhangjiakou Railway in the past century.
