Geographical Study on Regional Changes due to the Motorization in East Japan

本研究的目的是明确机动化对区域复合要素的影响。在此背景下，日本的机动化以较快的速度全面渗透全国。它既体现在物理方面，也体现在日常方面，如许多有限的高速公路系统的新建和停车场的整合。当然，这与区域各方面的发展密切相关。为解决上述研究目的，本文采用厘清机动化对区域要素的真实影响，并对各要素的影响程度进行排序的方法，选取东日本的样本区域，在宏观、中观三个区域尺度上进行研究。还有微型的。本研究的许多发现如下。(1)通过对宏观尺度区域之一的东北地区汽车流量的区域系统分析，汽车数量的增加带来了平均行程长度的相对减少，这反过来又对城市中心功能的提升和彼此的独立性起着重要作用。(2)因子分析和聚类分析结果表明，松本盆地是一个中尺度区域，在松本城市周边的商品流动圈内，最初与传统特征相关的地域性已明显被城市化、工业化和机动化的新货币所取代。(3)在山形县小泽市和茨城县八崎町等微尺度地区，机动化极大地扩大了商品流动范围和居住面积，进一步成为刺激居住格局创新的动力。

The aim of this study is to make clear the impact of motorization on the composite elements of region. In this context, the motorization of Japan has shown its complete penetration throughout countr with higher pace. It is reflected in both physical and ordinary facets such as new construction of many limited expressway system and consolidation of the parking lots. Definitely, this is closely interrelated with the development of various aspects of region. To solve the study aim mentioned above, we adopt a method that the real impact of motorization on the regional elements is clarified and the intensity of the impact is ranked for each element, doing our research on sample areas of East Japan, which are selected for three regional scales: macro, meso. and micro ones. Many findings from the study are obtained as the following.(1) Through analyzing the regional system based on the automobile flows of Tohoku district, one of macro-scale regions, the increase of number of automobile brings about relative decrease of average trip length, which, in turn, acts an important role in grading up the function of urban centers and the independency of each other.(2) According to the outcomes of factor and cluster analyses to extract major elements defining the regionality of the Matsumoto basin, a meso-scale region, within the commodity flows sphere around Matsumoto city the regionality initially associated with traditional features has been obviously replaced by new currency of urbanization, industrialization, and motorization as the definition factors.(3) In Obanazawa city of Yamagata prefecture and Hazaki-machi of Ibaraki prefecture, micro-scale regions, the greate expansion of commodity flows sphere and areal extent of living are given by motorization, which further become to stimulate the innovation of housing pattern.
