Source And Sink

Urban fringe areas are the core carrier for the balance of carbon source and sink in urban regions and the concentration area for conversion of land used for carbon emission and sink. With the support of interpreted data of remote sensing images, through combination of the “Breakaway Point” Analysis Approach and the Index Bound Method, the paper obtains the range of fringe areas of Nanning City and discusses about the driving force mechanism of spatial expansion of lands used for carbon source and sink at the urban fringe areas. The results show that conditions of natural terrain, social and economic factors, development of communication and transportation, urban planning and control, social culture and mass psychology form the driving force mechanism of spatial expansion of lands used for carbon source and sink at urban fringe areas.

The City

A spatial-equilibrium model of a local public economy is developed in four settings. Each setting is distinguished by two factors: whether the city is ‘open’ or ‘closed’, and the method used to determine the urban fringe. The four settings are contrasted by use of a numerical illustration.
