ABSTRACT

This study shows how the urbanization of the Seoul Metropolitan Region(SMR) has progressed for the last 30 years and what its characteristics are. So far, the urbanization of the SMR has been analyzed through societal and economic indicators or statistical data. Here, however, the urbanization of the SMR is analyzed in the aspect of urban planning that places more emphasis on the spatial relation. More specifically, this study examines the urbanization of the SMR from the land use changes, accompanying to the urbanization, and the spread process and characteristics of the urbanized area. In order to analyze the dynamic urbanization process of the SMR effectively, here, remote sensing and GIS techniques are used. The satellite images used are Landsat MSS and TM, which are a total of six from 1973 to 2000 for time series analysis. The urbanization of the SMR began to expand to the satellite cities adjacent to Seoul in 1980s. The rapid expansion of urbanization has reached a climax with the construction of five new cities in the SMR since 1990. Although the urbanized area seems to have no specific direction and pattern regionally, it has regular direction and pattern when it is seen as a whole of the SMR. The development direction is closely related to the development condition. If we understand this relationship, we can predict the development direction.
