An Empirical Research on Space Structure of the Commercial Cluster

在这个研究项目中，对秋叶原地区的空间使用情况进行了调查。在2001年至2003年期间，对索托神田地区所有建筑物的所有楼层进行了彻底调查。相应区域属于东京中心区，包含秋叶原电子城。研究的目的是探讨商业区域空间是如何在时间的长河中形成并动态演化的。通过对调查结果的整合，构建了完整的数据库。(1)测量方法：按单个建筑的每层制作一张测量单。通过逐一访问每个场地，根据准备的类别区分零售，批发，服务和住宅等空间用途。(2)数据库建设：通过输入完整的调查数据来构建数据库。(3)变更检查：标记用法的变更，并做简要的数据来澄清空间的变化数据库集成已经进行了必要的修改，使数据库可以用于时间序列分析。由于测量的基本单位是楼层，因此观察到楼层的划分和整合等现象。为避免数据重复或寻址错误，逐年增加修改收集关于索托坎达区的历史和地理数据收集历史和地理数据是为了了解索托坎达区的发展在更长的时间尺度。调查了地图、照片和航空摄影等文件来源，并通过与城市工程专家举行听证会，寻找利用这些经过验证的图形资源的方法。

1 A 3 year survey of all the building floor space usageIn this research project, space usage in Akihabara district was investigated All the floors of all buildings in Sotokanda district are thoroughly investigated from 2001 to 2003 period. Corresponding area belongs to the central Tokyo district and contains Akihabara electronics town. The purpose of the research is to investigate how the commercial area space is structured and it evolves itself dynamically in the passage of time. A complete datebase was constructed by integrating the survey.(1)Survey methods : A survey sheet is made in terms of the each floor of the individual building. By visiting each site one by one, space use such as retail, wholesale, services and residence are distinguished based on the category prepared.(2)Database construction : A database is constructed by inputting the complete survey data(3)Checking the change : Alterations of the usage are marked, and brief data was made to clarify the change in space.2 Data base integrationNecessary modification has been conducted so that the database can be used for time-series analysis. As a basic unit for the survey is a floor, phenomenon such as the division and integration of the floors are observed. In order to avoid the data duplication or misaddressing the modification is added year by year.3 Historical and geographical data collection regarding the Sotokanda districtHistorical and geographical data were collected in order to understand the development of the Sotokanda district in the longer time scale. Documents sources such as maps, photographs and aerial photography were investigated Methods to utilize such verified graphic resources are searched by conducting hearings to the city engineering specialists.
