This paper reviews the selected studies on LSC whose purposes are to especially contribute land use planning in case of Japan, So, this study examines the LSC's application to Korea based on Japanes LSC studies with a view to development of the methods on LSC for rational land use planning in our rural area. The result resolves itself into Table 2. However, it is undesirable to borrow from Japanes LSC studies like that, because of the difference of administrative,geographical,traditional,social and economical conditions. Therefore, it is necessary that the many case studies and examinations should be carried out in order to develop the methods on LSC suitable to Korean actual circumstances.
