Spatial and Temporal Evolution of Consumption Space in Airport Economic Zone Based on POI Data:An Empirical Study Based on Nanjing Airport Economic Zone
It is an important prerequisite for the construction of near-airport consumption space to grasp the development law of near-airport consumption and summarize the spatio-temporal evolution characteristics of near-airport consumption space.Based on the multi-period consumption space POI data and ArcGIS spatial analysis of Nanjing Airport Economic Zone,this study explores the spatio-temporal evolution path and the causal mechanism of the consumption space in Nanjing Airport Economic Zone under different development stages.The results show that the consumption space in Nanjing Airport Economic Zone exhibits a large-scale,diversified and networked development trend,and it has strong path dependence:(1)The number of consumption spaces shows a trend of first growth and then decline,and the attractiveness of near-airport areas gradually increases.(2)High-level consumption spaces gradually increase,and the degree of mixing spatial functions is greatly improved.(3)The distribution pattern presents the characteristics of"more in the northwest and less in the southeast",and a"cross-shaped"pattern is gradually formed.(4)The future development trend is in the direction of"northwest-southeast".
