Study on the Spatial Distribution of Beijing Time-honored Brand Snackeries in GIS
The Time-honored Brand snackeries are not only important name cards of Beijing, but also important parts of the cultural heritages of Beijing. Based on the investigation of Time-honored Brand snackeries in Beijing, the spatial features of the snackeries were summarized with the methods of buffer analysis, kernel density, and standard deviational ellipse. It aimed to provide advices for optimizing the urban caterings patterns, developing the Time-honored Brand caterings, and protecting cultural heritages. With the analysis of the spatial distribution of cuisines and catering classes, it concluded that Beijing Han dishes and Low-class snacks occupied a dominant position. 95% snackeries located in the 1000m buffer area of main roads, and the transportation is convenient. Beijing Time-honored Brand snackeries developed in an unbalanced way, their distribution center located in Xicheng district, and displayed the "Eastern-Western" pattern. They were aggregating in the central city,at the same time they were scattered in the periphery, and their quantities decreased generally from the center to the periphery as a development circle.
