JiSMART2022—024: A Study of the Spatial Distribution of Aged Gated Residential Communities in Qingdao Using Arcgis

Abstract

In recent years, upgrading aged gated communities have gradually become the focus of national projects, and therefore exploring the spatial distribution of aged gated communities is rather significant for guiding urban renewal and construction. This paper aims to investigate the spatial distribution and historical evolution of the aged gated communities (before the year 2000) of Qingdao from the perspectives of spatial agglomeration, spatial distribution trend, and spatial morphological evolution. By using the standard deviation ellipse and kernel density analysis of ArcGIS, three important findings can be concluded. Firstly, the distribution of aged residential communities in the major urban area of Qingdao generally shows multiple high-density agglomerations. Secondly, the overall spatial distribution presents a trend in the ‘northeast-southwest’ direction, and the most high-density areas have an obvious spatial correlation with the central business area. Finally, the aged gated communities built in different periods of time show increasing dispersion from south to north as time moves towards today. This is also consistent with the gradual development of the city as a whole moving towards the north direction. This study can provide clear data support to the development and evolution of aged gated communities in Qingdao, and possibly inspire more related studies
