Abstract:
We have evaluated the characteristics of how the green open spaces are arranged in the entire coastal zone in terms of the conservation and rehabilitation of natural environment. In this paper we categorized the green open spaces into three types (park, unused lands, and forestland/agricultural lands) from the perspective of sustainability and conservation and rehabilitation of natural environments. We also examined the characteristics of how the green open spaces are arranged in terms of the occupancy rate of the green open spaces and the green open space access distance. The following account results from this study: 1-the rate of the parks in the green open spaces becomes higher as the population density becomes higher. The parks access distance in the seaside areas is longer than in the inland areas. In the areas of the higher population density, the situations in the seaside areas are similar to the inland areas. 2-in the seaside areas, the rate of the green open spaces is mostly the unused lands. 3-in the areas of the lower population density and the inland areas, the forestland and agricultural lands as the remaining natural environment are 10 minutes walk from residential areas. With the analysis of this evaluation we propose that there need to be plans that embrace the significance of the arrangement of the green open spaces in both inland areas and seaside areas, and that support an organic integration of the green open spaces and other areas.
