Construction of Islands GIS and Index of Vulnerability-Geographical Change of Amami and Okinawa Islands

这项研究的目标包括从脆弱性的角度调查受调查地区的空间结构，即孤岛和冲绳岛。我们必须使用1985年、1995年和2005年的社会、经济和环境变量创建岛屿数据库，并必须创建岛屿地理信息系统。我们使用社会变量创建了脆弱性指数，并检查了空间结构。此外，我们从脆弱性的角度对Amami和冲绳群岛进行了实地调查。

The objectives of this study include the investigation of the space structure of the subject area, the isolated islands of Amami and Okinawa, from the perspectives of vulnerability. We have to create the database for Islands using social, economic and environment variables for 1985, 1995 and 2005, and have to create the GIS for Islands. We have created a vulnerability index using the social variable and have examined the spatial structure. In addition, we made a field survey for Amami and Okinawa Islands from the perspectives of vulnerability.
