摘要

Block restructuring has been strongly emphasized in Japan for renovating cities. However, little is known about the relation between block size and building shape. Moreover, the shape of buildings designed on a block after restructuring is unclear. In this study, the relation between block size and building shape is analyzed quantitatively, and a three-dimensional building shape is estimated by a model using an urban planning GIS data set of Tokyo. Results show the quantitative relation between block size and building shape, and the building shape image on the blocks. Higher buildings and buildings with a basement tend to be built in larger blocks, leading to efficient use of the maximum volume permitted in the block. In addition, the region composed by larger blocks can be spacious, because the range of building setback will be long in larger blocks. Designation of a high floor area ratio may induce integration and enlargement of blocks. Blocks are less likely to be partitioned in zones when a high floor area ratio is designated. 在日本，街区改造一直是城市改造的重点所在。然而，人们对街区大小与建筑形状之间的关系知之甚少。此外，城市改造后建筑物的形状对街区究竟有何影响也不太清楚。本文定量分析了街区大小与建筑物形状的关系，并利用东京城市规划的GIS数据集建立了一个三维的建筑形态模型。结果表明，街区大小与建筑形状，以及街区上的建筑形状图像之间存在定量的关系。较高的建筑物和有地下室的建筑物往往建在较大的街区里，从而使得该街区所允许的容积率得到最大限度的有效利用。此外，由较大的街区组成的区域可以很宽敞，因为在较大的街区中，建筑物的后移范围可以更长。选择较高的楼面面积比可能会引起大楼的集成和扩大。当选择了较高的楼面面积比时，街区不太可能被分割开来。
