Spatial pattern of urban functions in the Beijing metropolitan region

The morphology of a city affects its ecological and socioeconomic functions, and thus how a city is spatially structured has important bearings on urban sustainability. The paper analyzes the spatial pattern of Beijing in relation to its urban functions. Our results show that the 6 concentric ring-roads in Beijing provide a basic framework for the city's overall spatial pattern, and also give its apparent resemblance to the classic concentric zone theory. The paper identifies 5 concentric zones for Beijing based on a suite of urban functions. However, there are significant differences between the urban spatial pattern of Beijing and that depicted in the classic concentric zone theory. The study sheds new light on the urban morphology of one of the major Chinese cities, and provides needed information for developing plans to diffuse urban functions in Beijing.
