利用GIS空间分析方法，研究了北京超市的空间分布和变化趋势，发现超市主要分布在城市功能拓展区和城市发展新区，国内超市多在五环与六环之间，外资超市多在三四环之间，并沿放射状道路向外扩散。
With the aid of GIS-based spatial analysis methods,the paper discusses spatial structure and trends of supermarkets in Beijing.It demonstrates that the supermarkets mainly locate in urban function extended districts and new districts of urban development.More domestic supermarkets are between the fifth ring road and the sixth ring road while foreign or joint-venture supermarkets are between the third ring road and the fourth ring road.It also states that thesupermarkets diffuse along the radial roads from the urban center of Beijing.In the East,West,and Northwest,the supermarkets extend to five loops outside,while in the Southeast,they distribute within the fourth ring road.In the end,the paper proposes that the Supermarkets will achieve further development in the suburbs because of suburbanization of population and housing,rapid development of private cars,high land prices and intense competition from the center districts,and the guidance of government plans and policies.
