Research On The Influence Of Lanzhou Rail Transit Line 1 On The Urban Spatial Development Along The Line

The transformation of transportation system has a more and more close impact on the development of urban space,especially the urban public transportation system based on rail transit,which has a far-reaching impact on the development of urban space.Lanzhou city is a typical valley belt city in the northwest inland.The impact of rail transit construction on urban spatial development has great particularity.By analyzing and studying the evolution characteristics,mode and degree of urban space development within the service radius of Lanzhou Rail Transit Line 1 station,this paper forms a research conclusion with certain theoretical value,and provides reference strategies for urban space development under the influence of Lanzhou rail transit.Firstly,this paper analyzes the mode and experience of urban spatial axial development and belt urban spatial expansion under the influence of rail transit.Secondly,through the comparative analysis of urban space development and changes in the construction and operation cycle of Rail Transit Line 1,the location,scale and other basic information of urban space development and changes around each station are obtained.Then,the characteristics and modes of urban spatial evolution along the rail transit are summarized and analyzed,and some basic conclusions are drawn.Finally,it puts forward the urban space development strategy under the background of the interactive development of rail transit and urban space.As far as the spatial evolution characteristics are concerned,the spatial development of cities along Lanzhou rail transit is characterized by multi-scale evolution in scale,such as flake,block,dot,etc.;in spatial structure,it is characterized by the coexistence of multiple structures,such as circle,jump,fill,etc.;in spatial function,it focuses on the expansion of commercial and residential space,while the guidance of auxiliary function space is weak.As far as the spatial evolution mode is concerned,Lanzhou has gradually formed a multi center zonal axial expansion mode of urban space on the macro level,while on the micro level,the space along the rail transit has gradually formed a point like decentralized development mode and a central cluster filling development mode.Finally,through the analysis of the interactive factors and dynamic mechanism between rail transit and urban space development,this paper puts forward the macro measures of system guarantee and planning coordination from the perspective of spatial development,and puts forward the optimization of the public transport connection system of "public transport +rail" from the perspective of urban transportation system,and explores the micro measures of "common rail" operation of intercity and subway,so as to improve the urban space Agglomeration capacity and carrying capacity promote the high quality and sustainable development of urban space.
