Study On The Corridors System Of Xi'an Metropolis

The comprehensive corridor is an integrated city organization system which integrates urban transportation,functional organization,infrastructure and ground and underground linear space.It is an effective way to achieve regional and urban and urban space,urban functional organization,urban internal functional organization and its material energy,information flow and space,and it is by the transportation,ecological,social,municipal facilities,information,and the urban space elements such as coupling,the ground and underground space of the organic combination of organization system.Urban comprehensive corridor not only constitute the skeleton of urban spatial structure,but also organic composition of urban functions.The study of the layout of the comprehensive corridors of Xi'an International Metropolis is based on the basic theory of constructing a comprehensive corridor layout,and systematically analyzes the concept connotation,basic characteristics,categories,and spatial system composition of the comprehensive corridors.This paper through the analysis of the comprehensive factors affecting corridor layout,summarizes the comprehensive corridor space layout present a shaft type,mesh format and hybrid three layout form,and from three aspects: regional,district and block studied comprehensive corridor space layout,space layout in big xi 'an as an example in the end.The main conclusions of this paper are:(1)System for the corridor is the spatial organization of urban area,it is has two aspects of structural and functional features,system for the corridor space of metropolitan area by area,area and blocks of three levels.(2)The comprehensive corridor space layout is mainly affected by four factors,such as natural geographical environment,urban space structure,road traffic network and pipeline technology standard.(3)The layout of the comprehensive corridor of Xi 'an is influenced by natural topography,landscape pattern,urban structure,road network and special project layout,and presents a hybrid layout pattern.The layout of the comprehensive corridor in the metropolitan area of Xi'an should conform to the trend of the mountains and rivers,with the spatial structure of the natural geography as the base,the external transportation system as the backbone,and the layout of the regional infrastructure,forming the spatial layout pattern of "one corridor,two screens,three rings,eight waters and eight-radiation".The comprehensive corridor layout of the main urban area of Xi'an should be based on the characteristics of the geographical conditions and facilities construction in the main city of Xi'an,taking the road system of the main city as the skeleton,combining the layout of the municipal engineering and the ecological green space,and forming the spatial structure form of the 3D "three-ring" and "multi-corridor" in general.The comprehensive corridor layout of Xi'an district level should closely combine the features of functional space organization,traffic passage and greening pipeline laying.In combination with the technical requirements for the construction of the integrated pipeline corridors in the main roads,the comprehensive layout shall be strictly followed in accordance with the technical specifications,and the underground and aboveground space shall be organic.Together,a comprehensive corridor system with integrated traffic,life,ecology and facilities will be established.
