ABSTRACT

摘要

Spatial rationality revealed by mathematical analyses seems less important in Japanese urban planning.In the case of Japanese provincial cities, the urban area of them has been expanded rapidly in this 50 year; therefore, the area around railway station is not the centre of efficiency anymore after the urban expansion. However, conventional residents still believe that the centre locates in front of the station. Such image of centrality might have already been forgotten by young people who have no experience of those days when the area was crowded. Nevertheless, this partiality seems to have been penetrating deeper to Japanese society, and not overcome yet.

数学分析揭示的空间理性在日本的城市规划中似乎不那么重要。以日本省级城市为例，其城市面积在这50年里迅速扩大;因此，在城市扩张后，火车站周边地区已不再是效率中心。然而，传统的居民仍然认为中心位于车站前面。这样的中心形象可能已经被那些没有经历过该区域拥挤时期的年轻人所遗忘了。然而，这种偏爱似乎已经深入到日本社会，而且还没有被克服。

Now, this research attempts to address this problem from different angle rather than relegating it to a mere irrational concept. We have called this persisting residents’ perception the 'urban kernel'.The purpose of this study is to investigate the urban kernel by means of new concept and find spatial rationality from them. We will reveal the spatial structure which cannot be explained solely by the conventional concept of Global and Local, but by combining a new indicator. An index called D-Local is a measure that is based on the idea of clusters indicated by Local.By using D-Local, we will be able to find a clue for solving ‘boundary problem’ in Global. This new approach enables us to investigate Japanese port towns of which the configuration has been influenced by multiple conditions such as waterfront geographic context, immigrants, navy bases and so on, contributing to the understanding of the complexity in Japanese modern cities.

现在，这项研究试图从不同的角度来解决这个问题，而不是仅仅把它归结为一个非理性的概念。我们将这种持续的居民感知称为“城市内核”。本研究的目的是通过新的概念来探究城市内核，从中寻找空间合理性。我们将揭示空间结构，这不能仅仅用传统的全球和局部概念来解释，而要通过结合一个新的指标。一个称为D-Local的指标是一种基于Local所表示的集群概念的度量方法。通过使用D-Local，我们将能够在全局中找到解决“边界问题”的线索。这种新方法使我们能够研究形态受到多种条件，如滨水地理环境、移民、海军基地等影响的日本港口城镇，有助于理解日本现代城市的复杂性。

Well done！
