Characteristics of Planting Structures in Public-Type Private Gardens in Urban Areas of South Korea

This study analyzed the planting characteristics and spatial patterns of public-type private gardens in urban areas. Five gardens in Daejeon and Ulsan were surveyed using quadrats to record tree locations and sizes and were digitized for layout mapping. Planting and analysis units were defined, and spatial patterns were examined using degree centrality. The gardens were classified into one site under mixed artificial–natural management and four sites under artificial management with commercial linkage. The mixed site featured both canopy and shrub layers, with spontaneous vegetation surrounding Pinus thunbergii, Pinus densiflora, and Prunus yedoensis. The commercial sites included either canopy-only or canopy-shrub structures. Lagerstroemia indica, P. densiflora, and Euonymus japonicus. were predominant in the temperate central region, while P. densiflora and Diospyros kaki. dominated in the southern region. This study identified the potential of public-type private gardens as planting models and their capacity to contribute to urban environmental improvement.
