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构成要素的影响。在此背景下，日本的机动化以更快的步伐在全国范围内全面渗透。它既体现在物质方面，也体现在日常生活方面，如新建许多有限的高速公路系统，以及对停车场进行加固。当然，这与区域各方面的发展密切相关。为了解决上述研究目的，我们采用了明确机动化对区域要素的真实影响，并对每个要素的影响强度进行排序的方法，以日本东部的样本区为研究对象，选取了宏观、中观三个区域尺度。还有微型的。研究结果表明：(1)通过对宏观区域之一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出行长度的相对减少，进而对城市中心的功能和相互之间的独立性起到了重要的作用。(2)根据因子分析和聚类分析的结果，提取了松本盆地这一中尺度区域在松本市周边商品流通领域内的地域性主要因素，原来与传统特征相关的地域性已经明显被城市化、工业化、(3)在山形县小班那泽市和茨城县崎崎町这两个微观区域，机动化极大地扩展了商品流动的范围和面积的居住范围，进而刺激了居住模式的创新。

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.
