Abstract
In korea, unplanned development activities has persistently taken place on non-urban area ever since the amendment of zoning in National Land Use Management Act in 1994. Even the restriction of regulation on activities enforced by the government have not been so effective to prevent unplanned development activities. In order to solve the faced problems, government has undertaken a task to reform Land-Use Management and Planning System, and newly introduced secondary district plan. This study suggests a role of secondary district plan based on survey conducted in current semi-agricultural land zone and semi-urban land zone where newly introduced secondary district plan will be implemented, and examines the function of secondary district plan with respect to the current development activities and system in non-urban area.
