Abstract

In this study, I intended to clear the subjects of green environment in the process of urbanization.
The green zone system, instituted in 1946, was intended to prevent the conurbation, to control the magnication of town, and to offer the welfare for town people and the selfsufficiency of vegetables, so that reconstruction of war-damaged city as Tokyo. This law limited the use of permitted building so hard as to restrict the building coverage of general buildings to 10%. In Tokyo, Keeping pace with the organizings of landed farmer, it was applied on wide area on the base of the open space for air force. But afterwards, owing to the increase of infraction of building coverage and construction without notice, to the many petition to repeal the green zone that confined strictly, this system was canceled by degree and was abolished at last. In the process of repeal, they thrached out the conditions of cancel, and considered the wholesome formation of urban area, for example to preserve the wedgeshaped green area to the utmost and to secure the area of park in high ratio being conditioned on the land readjustment.
