摘要
Snacks are an important part of the catering industry,whose spatial pattern distribution will directly affect the behavior of residents and tourists decision-making.Therefore,this paper chose 'Shaxian snacks' and 'Chengdu snacks' outlets in the downtown area of Beijing as the research object,taking POI data and GIS spatial data as data sources,using GIS spatial analysis and nuclear density estimation method,to make a comparative analysis of the spatial distribution characteristics of snack outlets in downtown of Beijing.The results showed that(1) distribution characteristics of snacks outlets in each district varied greatly.(2) Distribution differences of both snacks outlets in each circle was in significant.(3) Distribution of snacks outlets from the center to the periphery along the ring roads took on the "pyramid type".(4) Distribution of snacks outlet show stronger proximity to road than to subway.Distribution characteristics of the snack outlets included(1) Spatial distribution of the snacks outlets showed weak centrality.(2) The snacks outlets showed significant characteristics of spatial aggregation with great differences in internal structure.According to the above conclusions,combined with municipal planning,this paper according to the classification of the city,put forward suggestions on the distribution of snack outlets in Beijing,(1) Recombine the snack outlets in old urban districts.(2) According to the city functional orientation,redistribute the snack outlets in new urban districts.
