Abstract
This study aims to analyze the reason of the expansion of zoning area and the trend of development outside the zoning area for the local authorities that had expanded the zoning area though the population had decreased, and to propose the ideal way to the future zoning area. We clarify that the zoning area is an excessive setting in a lot of local authorities. A loose urban area is formed in the zoning area because development in the expanded zoning area doesn't advance, and the development outside zoning area progresses. Therefore, in the future, the zoning area should improve the quality by the promotion of proper urbanization with the improvement such as replotting project after controlling development outside the zoning area.
