The relationship between visible green ratio of streets and surrounding land uses in the central Tokyo

Abstract

Visible green ratio is widely used in planning for promoting greening in the urban area. Zoning and other urban planning measures can influence visible green ratio through defining land use patterns. Previous studies, however, have not clearly considered the relationships between visible green ratio and surrounding land uses. By surveying visual green ratio in various land uses in central Tokyo, this research has analyzed the relationship between the visible green ratio and surrounding land use. Results showed that vegetation coverage ratio, road width and variety of planting type have a significant effect on visible green ratio. We also found that it may be not effective to significantly increase the vegetation coverage ratio to improve the visible green ratio.
