Comparative Study of Metropolitan Area Multinucleation between Japan and U.S.

1.我们探讨了格鲁吉亚亚特兰大大都会地区多核化背后的社会经济形势。在分析了该地区的城市问题、民族问题和其他社会形态后，我们对边缘城市范式提出了质疑。郊区的独立性密切了不同社会群体之间的相互关系，将两极化的社会结构固定在空间结构上.我们明确了郊区中心城区和新CBD的内部结构。办公室正在向大型办公楼迁移，因为它们的地位。这种趋势使得内部结构更加分散的模式支持的汽车。它是影响大都市区增长类型的重要因素.在日本，通过对生活行为模式的分析，阐明了20世纪90年代大都市地区的新趋势。东京CBD的上班族首次减少。CBD的商业功能停滞不前，以汽车为支撑的郊区购物行为明显增多.我们以前没有发现的郊区的经济联系现在正在增加。结论：在日本和美国，我们发现了以汽车为支撑的空间结构，分散的结构。但由于中心城市和CBD的同心结构，在火车的支撑下，重叠而不清晰。日本CBD的内部结构也在向分散型转变。这种相互依存的结构对生活质量有着重要的影响，但我们应该从环境的角度来考虑交通方式。

1. The sico-economic situation behind the multinucleation of the Metropilanta Area in Atlanta, Georgia, we approached. After the analysis of urban problems, ethnic and other social patterns in the area, we have the question to the Edge City Paradigm. The independence of suburbs closes the interrelationship between different soial group, and fix the polarized social structure in the spatial strucuture.2. We made clear the intra-structure of suburban downtowns and new CBD.Offices are moving to big office towers because of their status. This trend makes the intra-structures more dispersed pattern supported by cars. It is a important facter in the growth types of metropolitan areas.3. In Japan, new trends of 1990s in metrpolitan areas are clarified through the analysis of behavior pattern of life. The office workers in the Tokyo CBD have decreased for the first time. Commercial functuions of CBD) is stagnant and suburban shopping behaviors supported by automobiles are evidently increasing.4. Economic connections in the suburban areas that we have found no so much before, are now increasing. Various kind of sunbuban accumulation appeared.Conclusion : In Japan as well as US, we found the spatial structure supported by automobiles, dipersed structure. It is however overlapped and not clear by the concentric structure of central city and CBD supported by trains. The inrta-structure of CBD is also changing to dispersed pattern in Japan. Thsese inter-dependent structure is very important for the quality of life, but we should consider about the traffic mode in the view of environment.
