주거밀집공간의 도시 어메니티 간 공간적 연관성 분석 : 서울특별시를 중심으로 = Spatial Association between Residential Density and Urban Amenities : A Case Study of Seoul, South Korea

다국어 초록 (Multilingual Abstract)

This study empirically examines the spatial relationship between densely populated residential areas and urban amenities in Seoul and identifies facility‑type disparities and policy implications across different population‑density tiers. By integrating 100 m × 100 m population‑grid data from Statistics Korea with amenity data from the Seoul Metropolitan Government, and by applying the Intertype L12(r) function, the analysis quantifies spatial correlations for high‑ (≥ 1,000 persons/ha), medium‑ (≥ 500 persons/ha), and low‑density (≥ 250 persons/ha) zones. Results indicate that public‑service facilities— such as evacuation shelters, libraries, community centers, and bus stops—exhibit consistently significant clustering across all density levels, whereas neighborhood‑oriented commercial amenities—such as real‑estate offices, service shops, and sports facilities—tend to be more closely located to residential areas as density decreases. Conversely, metropolitan‑scale facilities, including museums, art galleries, and subway stations, generally show weak correlations with population density. These findings suggest that locational strategies vary by facility type: overall accessibility tends to be secured in high‑density zones, whereas low‑density areas experience amenity‑specific gaps. By quantifying interactions at a micro‑spatial scale, this study offers an empirical basis for promoting spatial equity and improving facility allocation, emphasizing the need for finely tuned siting strategies that account for both population density and the functional characteristics of amenities in future urban planning and public‑service policy.
