Abstract

Currently, the eco-harmonization in watersheds has been gathering a lot of attention. To establish environmental management methods of watersheds and cities is a key issue. The watershed is consisting of various sizes of units; watersheds of large rivers, of small rivers, and small watersheds which are divisions of a river's watershed. The purpose of this paper is to analyze transitions of the green space environment based on small watersheds, using GIS, on the scale of the Master Plan for Parks and Open Spaces. Firstly, we prepared basic data; small watersheds, land use and present vegetation, and analyzed relationship between environmental capability and transition tendency of forest area in a small watershed. Secondly, to investigate tendency of urbanization and distribution of green spaces, we classified small watersheds into several groups by the cluster analysis. The analysis of component ratio of vegetations of each group clarified qualities of green spaces of small watersheds.
