Study On The Locating Supermarket Based On GIS

With the development of market economy and the improvement of people's living standard, China has become a consumer market in which there is great chance. The number of supermarket is steadily increasing, and as the result the supermarkets are popular by town inhabitants. With supermarket growing rapidly and the increasing competition in the retail markets, properly location is the important to run supermarket. Ones can locate a supermarket in which has most potentiality of investment with the help of analysis of location.As a new technology, GIS has been successfully applied to many domains. Especially it suits to urban planning because of the particular function of it's spatial analysis. GIS has powerful functions in data processing and spatial analysis, which realizes the combination of qualitative analysis and quantitative analysis. The dissertation puts forward some viewpoints based on the domestic and overseas theoretic researchs and practices related to the locating supermarket.Based on the analysis the indexes of the location of supermarket, we pay more attention to three application analytical indexes: spatial distribution of population numbers, traffic accessibility, competition between different firms, having realized the quantitative and visual analysis of the market area.We got the spatial distribution map of population density by spatial interpolation, in which the population data are distributed on the grids. The results of the distribution of interpolated based on GIS is closed to a real population distribution. The combination of the spatial interactive models and a shortest path algorithm for public transit network is analyzed by supermarket's accessibility based on pedestrianism and public transit.This methods may be used to investigate potential supermarket's locations.The quantitative analysis about the supermarket's market area is realized based on trade mode of Lashmanan and Hansen, which mainly includes spatial distribution of population, traffic accessibility and free competitionbetween different firms.At last, The paper gave an example about locating supermarket by the approach as mentioned above, the research result shows that the location of supermarket are reasonable, the locating supermarket based on GIS is feasible.
