ABSTRACT

The purpose of this study is to clarify the spatio-temporal characteristics of land cover changes across the Seoul metropolitan region including the Seoul-Incheon urban corridor observed in Landsat satellite imagery for the recent decades (1984~2014). Analyses of supervised classification of Landsat imagery at each decadal interval demonstrate that an east-west directional conurbation between Seoul and Incheon was formed due to an explosive urban sprawl in Seoul before the 1990s as well as those in Incheon and Bucheon after the 1990s. In the 2000s and onward, complex patterns of fast urban sprawl toward outskirts have been observed along the extended metro lines and major roads beyond the Seoul-Incheon in the areas of green belt appeasement urban conurbation corridor. It is clearly shown that significant magnitude of green space was sacrificed due to mega-urbanization around Seoul-Incheon areas over the last several decades even though the timing of urbanization in each region varies. Overall, these results suggest that re-consideration regarding the greenbelt appeasement policy since the mid-2000s is needed for pursuing thermally more comfortable conditions in the Seoul metropolitan region in the sustainable perspectives.
