The Retail Business Structure of the Metro Site Based on the Information Entropy——A Case Study of the 15 Subway Site in Guangzhou
研究了城市轨道交通对站点周边零售商业布局的影响，以广州15个地铁站点为例，发现站点位置、类型和开通时间会影响零售商业结构的均衡度。
In order to know more about how does the urban rail transit impact on the layout of the retail business around the station,we used the information entropy model,the equilibrium degree model and dominance degree model,this paper,based on the location,type and opening time of the subway site,to discuss the inner link between the urban railway system and the retail business structure of the metro site,and analyze and evaluate the retail business structure of the subway site on the 15 subway site in Guangzhou. The results showed: firstly,affected by the location of metro site, which is according to the order from the center to the edge,the information entropy of this case presents an inverted ushaped curve model,which displays that retail business structure,locating in the suburbs,is the most balanced zone. Secondly,affected by the different types of metro site,the transport interchange point is the most balanced retail business structure. Finally,the later the metro site open,the more balanced the retail business structure is. The above conclusions have important implications for recognizing and planning the layout and development of retail business along the urban rail transit.
