Abstract
This paper conducted a comparative analysis of the “Residential Self-Sustaining Area”, and “Regional Circulation and Ecological Sphere” as the approach that take into account the characteristics of both urban and rural and considers the range of their effects as an area, in order to clarify its characters and relationship. As a result, it was found that the former aims at efficient supply of urban functions to rural areas, while the latter aims at circulation around natural capital in rural areas. It also became clear that each area plan takes the opposite position in terms of urban intensification and rural decentralization, and both concepts are coming closer as time proceeds.
