Abstract

Abstract

Spatial vitality is an important factor influencing urban development. Based on POI data, relying on the ArcGIS platform, the distribution of urban vitality spaces in the main urban areas of Chengdu was studied from the perspectives of mathematical spaces and phenomenon data by using the analytic hierarchy process, coefficients of variation, nearest neighbor coefficients, kernel density analysis, spatial autocorrelation analysis and other methods. The distribution characteristics of urban vitality spaces were summarized, and the influencing factors on urban vitality were discussed. The conclusions were as follows:1) the spatial distribution of facilities of interest points in the main urban area of Chengdu was of obvious centripetallity; 2) there were some differences in spatial distribution patterns and agglomeration centers of various facilities; 3) the distribution of Chengdu's spatial vitality was of "three-circle mode"; 4) the vitality space had a strong spatial positive correlation with the population distribution and road-network density.
