| As a typical traditional business,the food market is closely related to the daily life of urban residents.In recent years,the food market has become the focus of urban space governance,and its survival and development is a major challenge for food market operators.On the other hand,how to simultaneously meet the rigid needs of residents’ daily life and the requirements of urban environmental governance has become a major problem faced by government managers.The research is based on a 2019 carpet field survey of different forms of food markets in Beijing’s Third Ring Road,combined with online open data and mobile positioning data,and the various forms of food markets in Beijing’s Third Ring Road are classified,aggregated and integrated according to the number of stalls.And combined with the distance logic represented by the central place theory and the topological logic represented by the space syntax to quantitatively analyze the spatial characteristics and influencing factors of the distribution and scale of the food market.The conclusion shows that: under the urban scale study,the food market in Beijing’s third ring road has a certain weak correlation with the residential population in a small area in terms of distribution quantity,and has a certain correlation with the residential population in the medium scale in terms of the scale reflected by the number of stalls;However,neither the number of distribution nor the scale is significantly related to the working population and the spatial accessibility of different scales;at the same time,it is found that the distribution number and scale of the food markets in the Third Ring Road are affected by the number of public transport stops within a larger scale.The impact is more significant,and the larger the size of the food market,the stronger the impact;in addition,supermarket chains that sell fruit and vegetable products often have a stronger spatial co-occurrence with traditional vegetable sheds at the macro-city scale,and the two are attracting each other.They compete with each other in the environment,and scattered stalls can better fill the missing part of the two in the city.The high-precision research results of the case block scale show that,except for a few case areas dominated by residential areas,there is a strong correlation between the size and density of the food market and the residential population at medium and small scales.The size and density of the market is related to the working population at medium and small scales.The distribution density and size density of food markets in most case areas are completely independent of the population of the blocks within this range;There are obvious correlations between the two characteristics,and after the overall high-precision data processing,it is re-derived.It is found that the scale and density of the overall food market in Beijing’s third ring road is related to the spatial topology of urban roads.By studying the distribution law of self-organizing functions such as food markets in the city,it is possible to better explore the relationship between the spatial characteristics of self-organizing functions and the street morphological structure in the block where they are located,the accessibility of major urban roads,and urban functional formats.Reasonable suggestions are given for the location and layout of different regions and different types of food markets in Beijing’s Third Ring Road.Also from the government’s point of view,for the spontaneously formed food market,its size and distribution density are more affected by traffic conditions,so its spatial governance cannot simply refer to the 1,000-person/10,000-person indicator or its service radius,but the food market should be placed in the spatial form of urban streets,starting from the density-based indicator of 1,000 people/10,000 people,and implementing differentiated standards according to the traffic accessibility of each block,avoiding“one-size-fits-all” control policies”. |
