The Allocation Pattern of Open Spaces in Consideration of population at Tokyo Bay Coastal Zone

Abstract

To gain suggestions on how open spaces should be allocated in coastal regions where urbanization has progressed in recent years, this study sought to understand the Tokyo Bay coastal zone in terms of the percentage of open spaces and access distance to open spaces for the land use conditions according to the population density and distance from the coastline, and from this, a comparison and assessment was made of the allocation characteristics of open spaces in the coastal and inland areas. These results revealed the allocation characteristics showed that for open spaces in the coastal area, (1) the access distance was larger in areas with low population densities; and, (2) for high population density areas, the percentage of open spaces was lower than inland areas at a population density of 250 to 300 people/ha, and the same trends as inland areas(high percentage of open spaces and small open space access distance) were observed at population densities of 300 or more people/ha. It was pointed out that when studying the allocation of comprehensive open spaces for the entire coastal area, a plan is needed for utilizing and supplementing the strong and weak points between each other in the open space allocation characteristics of coastal and inland areas.
