Abstract
This paper aimes to consider'the techniques used on the plotting of residential area and the plotting a block in the post towns, and to make clear what its character has had influence upon the present city area. The main results are as follows. . 1) The urban pattern of the post towns had had the linear town on the Nagasaki Highway, and the site shape (d/f) that had plotted on either side of its street had had the slender shape, and the outside of its town had been divided by the natural fence, such as the seashore, the river, the wood, and the like. 2) The frontage of a lot had shown a tendency to converge into 3 - 5 KEN (6〜10m). The other side, its depth had shown a tendency to scatter a little into 15-30 KEN (30-60 m), under the influnce of the land-form. 3) The principles of its planning had used the module of 35 KEN and the technique of the vista. 4) .Its characters of the plotting had degraded on the ground of the inconsiderate'town planning. 5) The single lot plotting in the block had changed into the double lot plotting, over and above this, it has changed into the plotting the four side. 6) Its variation has produced the back sites and the alleys, in no small numbers. And the strong correlation between the back sites and the alleys was confirmed.
