Spatial Comparison Analysis of Old and New Urban Areas based on Spatial Syntax and POI Data Correlation:Taking Old Urban Area and Honggutan New District of Nanchang City as Examples
With the help of POI data,the urban space of Nanchang Old Town and Honggutan New District is studied using Depthmap and ArcGIS kernel density estimation method and buffer zone analysis to analyse and compare the POI clustering of daily service facilities and its correlation with the road space structure of the two cities.The results found that in the urban space of the old city,the local integration degree of road space structure is significantly correlated with the POI concentration of daily service facilities,the core locations of the POI concentration of six types of daily service facilities are diverse,and"food and entertainment"is not correlated with the road space structure;in the urban space of Honggutan New District,the global integration degree of road space structure is significantly correlated with the POI concentration of daily service facilities.In Honggutan New District,the global integration of road space structure is significantly correlated with the clustering of POI,the core location of POI clustering of six types of daily service facilities is single,and"service and accommodation"is not correlated with road structure.
