On the characteristics of open spaces in the urban area concerning the transition and continuation

Abstract

In order to conserve valuable open spaces in the urban area, it is necessary to explicate the process of their transition and continuation, and the factors afffecting them.
It is possible to grasp the open spaces' transitions in relation to the land use's transition of the surrounding area and it is assumed that there are two different kinds of transition. One is a large transition which changes even the land use category of the area and the other is a small one which varies within one land use category. Hence, this study attempts to investigate and analyze the open spaces' transitions in views of both cases-large and small transitions-to explicate the process.
In conclusion, through these investigations and analysis in Minato-ku which is located at the center of Tokyo, this paper maintains that urban open spaces should be conserved by means below, 1) Creation of public open spaces by enlargement of public spaces, 2) Preservation of non-public open spaces by restraint of the housing lot subdivision and 3) Promotion of public and common use.
