Rurban decline in Rurbanaized Area on Metropolitan Region and Correspondence in Community Planning

本研究将日本大都市圈城市边缘的区域问题称为“乡间衰败”。本研究的目的是：1)通过实地研究的区域结构和人口变化指标，了解产生人口减少的乡镇化地区的空间特征。阐明了人口减少带来的区域问题的现实性，并对区域规划中提取区域问题及相应问题有了基本的认识。在日本，由于经济的快速增长，形成了不同于城市和农村的城市化(Konjuuka)区域空间。通过对环东京都市圈100公里范围内2000个行政单元的统计分析，认为都市圈人口正在减少，并存在居住环境进一步恶化的可能性。基于时间序列分析，将不同类型的都市圈分为三类。明确了社区重组的条件，并对三种不同类型社区居民的问卷调查结果进行了分析。在此基础上，提出了城市居住综合体生命意识与地方活动关系的社区模型。
