東京都心部のランドスケープ変化と樹林地の偏在性に関する研究

Abstract

In the urbanized society, the influence of human activity is reflected greatly, the ecosystem which exists there is peculiar to urban area. In the process of urbanization, green spaces and forests have been decreased. Especially, the influence appears in the center of Tokyo because of extreme urbanization. The purpose of this study is to explore landscape changes from the past to the present along with the land use change, and analyze the relation with landscape and geographical features. The research area was 6400ha in area and 34.5km in circumference which corresponds with JR Yamanote line. The transition for more than 100 years from Edo to the present was compared about six periods. We have exploited lands and made uniform city, although the relation of landscape elements and geographical features become stronger and stronger, it is prove that scarcity and value of green spaces and forests in the location are much precious as the years go by. In the relation with the geographical features of the landscape element, residential lot which contain forest, residential lot and meadow are unevenly distributed among plateau, forest, residential lot which contain forest, field and residential lot which contain meadow are unevenly distributed among slopes, residential lot and residential lot which contain meadow are unevenly distributed among flat lands.
