The Formation Principles of the Autonomous Area in the Area of Setonaikai seen from Human Settlements and Network Structure Based on Indigenous Value

本研究通过对濑户内海沿岸地区的实地考察和相关文献、地图的分析，考察了该地区的人居环境，试图了解濑户内海沿岸地区的景观特征和土地可持续利用体系。研究证明，具有本土特色的节庆和仪式空间、居住和聚落空间与自治区、海岸带网络结构和周边聚落融为一体。基于濑户内海地区的特殊性或结构构成，我们更深刻地理解了基于行政区以外的海岸带和地形特征的“生态单元”的空间重组是什么。

This study has attempted to understand the characteristics of scenery in the coastal zone of Setonaikai and the system of sustainable land-use by examining human settlements in the area through fieldwork in the coastal zone and analysis of relevant documents and maps. The study has proved that spaces used for festival and ceremonial purposes, and habitation and settlement spaces with the indigenous characteristics are integrated with the autonomous area, network structure of the coastal zone and surrounding settlements. On the basis of the special or structure composition of the area of Setonaikai, we gained a deeper understanding of what the reorganization of spaces by "ecological unit" is based on the coastal zone and topographical features which exist beyond its administrative district.
