An Analysis of the Proportion of Conserved Original Landforms and the Transformation of Their Distribution Patterns During Different Development Phases of Tama Newtown, Near Tokyo

Abstract

This study examines proportion of conserved original land forms and transformation of their distribution pattern in each development phase within the areas between B-1 (1971) and B-6 (1999) districts (1, 356ha in total) at Tama Newtown. The result indicates that I. 114.3ha of original land forms (51 locations), approximately 8 percent of the total area within B-1 to B-6 districts, has been remained so far, including 108.1 ha of areas (45 locations) where original land forms have been conserved and protected as integrated part of public parks or green conservation areas. This study also clarifies that there are significant changes during 1990s development phases from the initial development stages (1970s) such as II. overall conservation of original land forms with clusters of different topographic features III. increasing rate of conserved original land forms within the total development area Therefore, development methods at the latter stages at Tama Newtown are characterized by growing tendency to utilize potentiality of original land forms and conserve them as integrated part of public parks with respect to characteristics of undulating topography of Tama hills.
