As the urban population continues to increase, cities grow through the expansion of high-rise and high-density residential areas, which demand good living environments to improve citizens’ quality of life. This study is based on the apartment type proposed by Moon Soo-young(2011) in accordance with the layout pattern of green spaces in three apartment complexes located in Dalseo-gu, Daegu Metropolitan City. The purpose of this research is to discover the causes of the high nutritional rate and successful planting method, as well as to suggest a plan to improve the planting structure(general complex, built apartment). According to the study results, the green area ratio of the study was the highest with 44.7% of the total area, followed by Wolbahil state(center type) with 30.3%, and the Bible Jeongnam Town(type of arrangement around buildings) with 27.3%. Shared facility centers were placed outside the apartment buildings in common with the type of arrangement around the buildings and the type of centering arrangement, and the coverage rate in the apartment complexes increased. There are many underground parking lots in the vicinity of the buildings; the center type of the buildings and the parking lots for the disabled are located underground. In general, residents use the underground parking lot, and the ground greenery ratio is higher than other types. Through the analysis of the facilities in the complex according to the type, we found the cause of high green ratio and good planting method and suggested an improvement plan for the general and constructed apartments. In the general apartment complex improvement plan, it is possible to increase the green area by minimizing the single-story buildings such as the shared facilities center and arranging these facilities in the apartments. The number of entrances is reduced due to the connectivity between underground parking lots. Reducing the area of the road within the complex can reduce the number of green spaces. It is important that water pipes are laid mainly under broad-leaved trees and that the plant structure is multi-layered. In order to estimate the construction of the apartment, we propose a method to construct the green space in three dimensions by using methods such as wall greening and rooftop greening. It is possible to utilize enough spaces to waste through the plant materials. In the plant structure, a cluster planting was arranged and the shrubs and plants were placed in the complex.

본 연구는 공동주택단지 용적률변화에 따른 녹지면적 및 녹지구조의 변화파악을 목적으로 수행하였다. 대상지는 용적률 100%이하, 용적률 250%이하, 용적률 250%이상의 세 유형으로 구분하여 각 유형별로 2개소씩 선정하였다. 1970～1980년에 조성한 용적률 99%인 화곡제2주공아파트와 용적률 73%인 개포주공아파트는 녹지면적 비율 40.23～44.23%, 녹지 폭 3～ 15m 녹지 량 1.06～1.71㎥／m2, 교목층 식재밀도 0.04～0.06주／m2 관목층 식재밀도 0.06 ～0.20주／m2이었다. 1990년대에 조성한 용적률 226%인 등촌주공아파트와 용적률 240%인 개화 아파트는 녹지면적비율 24 16～26.16%, 녹지폭3～7m, 녹지량 0.84～l.54㎥／m2, 교목층 식재밀도 0.18～0.31주／m2, 관목층 식재밀도0.15～0.35주／m2이었다. 1990년대말에 조성한 용적률 269%인 한보구암아파트와 용적률 376%인 동아3차아파트는 녹지면적비율 23.47～25.53%, 녹지폭 2～6m, 녹지량1.06～2.12㎥／m2, 교목층 식재밀도 0.25주／m2, 관목층 식재밀도 0.22～0.37주／m2이었다. 용적률변화에 따른 녹지구조 분석결과 녹지면적은 용적률이 높을수록 넓었으나, 녹지량과 식재밀도는 용적률의 변화와 상관없이 전체적으로 낮은 상태이었고 식재구조는 외래종위주의 단층구조이었다.
