Study on Future Image of Urban Area Considering the Condition and Flow of Housing and District Environment at Tokyo Central 6 Ku.

1992年修订的《城市规划法》规定：1.将8个分区划分为12个分区；2.为中高层建筑设立专属居住区；3.推开有义务制定城市总体规划的地方当局。根据这一规定，地方当局审查了分区制度，制定了总体规划。对于东京都地区，本研究旨在明确未来的城市形象，重点关注住房和地区环境，并对以下几点进行分析。1.回顾1919年以来城市形象的处理方式，制定了《城市规划法》和《建筑法规》(第2章)。2.从个别更新成为高密度的观点将主要由23 KU组成的地区划分为8类，并选择东京都政府《住房总体规划》中的15个区。然后，通过分析这些地区1981、1986和1991年3次土地和建筑用途的变化，考虑到《建筑法规》(第3章)的问题(第3章)。3.选择中高层建筑专属居住区的候选区域，作为分区审查时应考虑的重要问题。根据1995年东京土地利用调查数据，对山手线和东侧区域内的面积进行了分析，设置了1240个分区，每个分区包含相同的分区和相同的距离(第4章)。结果发现，现有的创建良好社区的分区体系(Machi-NAMI)有许多需要改进的地方，而且候选区域比东京都政府修订后的计划要大得多，因此，该分区的应用不能仅仅通过物理条件来讨论，必须需要土地所有者的积极参与。

By amendment of City Planning Act in 1992, the Act provides 1.subdividing zoning 8 into 12,2.Establishing Exclusive Residential Zone for Higher Stories of Medium to High-rise Building and 3.Putting local authorities under obligation to make Municipal Master Plan.With this provision, local authorities reviewed zoning system with master plan making.For Tokyo-Ku area, this study aims on claryfying the future image of urban area to focus the housing and district emvironment and analyzes the points shown below.1.Reviewing how the image of urban area had been treated since 1919, City Planning Act and Builiding Code established (Chapter 2).2.Grouping the area mainly consisted of housing at 23 Ku into 8 categories from viewpoint of becoming high-density by individual renewal and selecting 15 districts with Housing Master Plan of Tokyo Metropolitan Government.Then from analysing the change of land and building use among 3 times, 1981,1986 and 1991, for these districts, considering the problems of Building Code(Chapter 3).3.Selecting the candidate areas for the designation of Exclusive Residential Zone for Highr Stories of Medium to High-rise Building which should be considered as important issues at the review of zoning. With Tokyo Land Use Survey Data 1995 we analyze the area within Yamanote-Line and East Side area and set 1240 zones where each zone includes same zoning and same FAR(Chapter 4).As the results, we find that there are many points which should be improved in existing zoning system for creating good community (Machi-nami)and that the candidate areas are rather bigger than a revised plan made by Tokyo Metropolitan Government then the application of the zone can't be discussed not only by phisical ondices but must need the positive participation of land owners.
