GIS Study of Sububan Agglomerations.

1.通过航空照片和地图的土地利用资料，分析了亚特兰大大都市区郊区商业区的发展和旧CBD的变化与衰落。结果表明，该工艺流程清晰. CBD已分化为几个功能各异的城市群。郊区商业区是由郊区的购物中心和小型办公区聚集而成的。针对小空间单元的统计数据，对GIS数据进行了检验。利用小单元GIS技术对日本和美国的大都市圈进行了比较研究。亚特兰大的就业数据显示了郊区聚集的过程，但日本的数据不足以分析。其单位（人口普查底图数据）没有纳入人口统计，分类也不够。日本主要都市圈人口普查通勤数据的GIS数据库已经完成。分析结果表明，1965- 1995年郊区通勤量急剧增加，并具有一定的特点。地理信息系统通过专利数据分析公司间网络的技术创新。他们表明，郊区紧密的网络现在非常重要，特别是对小型和年轻的公司。

1.The growth of suburban downtowns and the change and decline of old CBD in Atlanta Metropolitan Area are analyzed with the sourece of landuse by aerophotos and maps. As the result, the following process are made clear. CBD has devided to a few agglomerations with defferent functions. suburban downtowns are agglomerated from suburban shopping center and small office districts.2. In the view of statistical data with small spatial unit, GIS data are checked. Comparative study are made between Metropolitan Areas in Japan and US by GIS with small unit. Emplyment data in Atlanta showed suburban agglomeration process but Japanese data are not enough to analyse. Their unit (base map data of Census) is not integrated to the Establishments Statistics and the classifications is neither enough.3. The database on GIS has completed about the Census Commuting data of major Metropolitan Area in Japan. As the result of analysis, they showed sububan commuting is drastically increasig and chracteristic in commting flows 1965-95.4. Technological innovations by inter-firm networks are analysed by GIS through the data of patents. They show suburban close network is now very important especially to the small and young firms.
