Study On Spatial Distribution Optimization Of Commercial Facilities In Subway Station Area Based On Consumption Demand

With the rapid development of China's rail transit in recent years,the development of commercial service facilities around the subway station has brought about a new round of development momentum and opportunity.And live as the most widespread type of subway station,at the same time is closely related to people's daily lives o f the subway site type,the station domain to study the spatial layout of the commercial service facilities has strong practical significance.However,Chinese scholars type settled in the subway station and subway station domain research in the field of commercial service facilities space layout is less,Dalian subway opening time is shorter,because of its much less about the field research,foreign related to community commercial,residential type subway commercial research also has its limitations,cannot be fully applicable to the domestic research,the research content of this paper also has strong theoretical significance.First of all,the author has studied the theoretical basis of this study and the research progress of the spatial distribution of commercial service facilities in residential subway stations in C hina and abroad through literature review.And from Guangzhou,Beijing,Hong Kong and Singapore's living type subway station,case analysis and field survey of Dashadi station in Guangzhou and Beijing Huilongguan station,for later study to lay the good foundation of theory and practice.Then,the author in Dalian city as an example,according to whether the subway line and station domain contains large commercial complex as a basis for select ing type four living subway station respectively on the subway users questioned in a survey for the analysis of the travel and consumption characteristics.The results of the survey of travel characteristics show that the subway users in Dalian residential subway station are mostly white-collar workers with high incomes,and office workers.Respondents who used the subway for commuting were the majority.The results of consumption characteristics showed that respondents had the highest frequency of use in convenience stores,restaurants,comprehensive markets,large and medium-sized supermarkets,and shopping centers and sweet shops.For large and medium-sized comprehensive supermarkets,restaurants,integrated markets,convenience stores,the nearest consumer demand strength.Based on the analysis of consumers' demand,the author selected four kinds of consumption high frequency at the same time demand intensity near the types of business services by using spatial analysis methods to analyze four class in the ArcGIS spatial distribution situation of commercial service facilities,combining GRITIC method of four station domain site commercial service facilities allocation situation assessment.Finally,create the four subway station space layout model of commercial facilities,and connecting with the consumer demand and commercial service facilities space analysis result,according to different commercial service facilities layout mode put forward the corresponding optimization strategy.Four living type subway station by Dalian domain the research of the spatial distribution of commercial service facilities,and hope to Dalian live type subway stations and other cities in other type of subway station around business development play a certain reference and guidance significance.
