The Study On The Vitality Of Underground Commercial Space With The Core Of Rail Transit

The rapid development of the city and huge commercial resources flow all need efficient and convenient urban rail transit to support. Therefore, with the characteristics of strong transport capacity and punctuality, high efficiency and low pollution, rail transit has become an important component of urban transit system and has been called the new attraction for urban development. In the vertical development of the city, it brings the huge flows of people, goods and information for the high-density central area; in the horizontal development of the city, it forms the new urban development zone and increases the contact of urban centers and the suburbs.As an important resource of comprehensive development and utilization for the subway station area, underground commerce can relieve the economic pressure brought by the construction of the subway, resolve the tense land use situation in urban centers, and is an important part of urban public space.This paper studies the commercial vitality of underground commercial space with the core of rail transit, aims to explore the characteristics and influencing factors of such commence and puts forward the improvement strategies accordingly. The research methods used in this paper is mainly space syntax, which is used to analyze the correlation between spatial relationship and social phenomena.As underground commerce embodies the duality of transit and commerce, so the analysis expends from both directions of transit and commerce. The analysis of transit is mainly from the space level, using space syntax to analyze the spatial configuration and make virtual distribution of people in the space; the analysis of commerce is mainly from the sociological level, using tracking research and big data to analyze the commercial activities of people and the profitability of shops. Select three kinds of underground commercial space, first make vertical contrast of the spatial level and social level of each monomer, and analyze the influencing factors of such commercial vitality; then make horizontal contrast of the influencing factors of each underground commercial space, and draw a general conclusion to propose guidance for underground commercial space which is constructed on the basis of rail transit development.There are three factors influencing the vitality of underground commercial space with the core of rail transit. First, it’s the commercial scale. A moderate scale can determine the economic benefits and is the premise of underground commercial benign operations. Second, it’s the format configuration. Format is closely related with spatial form, and is the preliminary auxiliary analysis. Third, it’s the transit accessibility. The underground commerce with the core of rail transit tools should take the transit accessibility as one of the basic requirements for design. By creating efficient and convenient transit environment.
