RESEARCH ON THE SPATIAL DISTRIBUTION OF PUBLIC SERVICE FACILITIES IN NANCHANG OLD CITY, CHINA BASED ON POINT OF INTEREST (POI) DATA

Abstract

In recent years, Nanchang City has focused on urban renewal, including the transformation of old residential areas. The spatial layout of various public service facilities in the city has also undergone significant changes. To improve the public service facility system, it is essential to analyse the spatial layout of various service facilities in the old city area. The Geographic Information System (GIS) technology combined with Point of Interest (POI) data was to analyse the spatial distribution characteristics, thereby drawing the following conclusions: Nanchang’s old urban area has less public service facilities in the edge area, and the spatial layout presents an imbalanced trend of “central aggregation - edge dispersion.” The density of various facilities around the subway is good, educational, and cultural facilities is highly correlated with other types of facilities. However, medical facilities and other infrastructure are in a state of obvious differentiation, especially in the edge areas. The above analysis proposed for relevant strategies and recommendations, thus providing a basis for future scientific arrangement of urban facilities.
