Evaluation of Supply Adequacy of Park Service in Suwon-si by Urban Park Catchment Area Analysis

In the city, the urban park contributes to the quality of citizen life in many ways, and the importance of the urban park as an urban planning facility is growing each day. In this study, evaluation of park service supply adequacy in Suwon-si, the difference in analysis methods, and the type of land use at urban park catchment area analysis were analyzed. As a result, there were remarkable differences between the two analysis methods. In Suwon-si, the catchment area by network analysis was only about 41% of catchment area by buffer analysis. However, when basic local authorities establish planning of parks and green areas, they use buffer analysis to calculate the park service area. It means that such calculations of urban park service areas may be wider than actually used. Also, because there were differences between urban park catchment areas by land use types, guidelines of planning parks and green areas will be adjusted. Although quantitative expansion of the park area is also important for the realization of green welfare, it is necessary to consider city characteristics such as the population size, population density, land use types, and so on.
