Taking Beijing as the study object, this paper based on POI service offered by online maps and the results of the 7th population census, used ArchMap for the visualized analysis of population movement and large-scale business in Chaoyang District. Then it proposed that the construction of rail micro-centers should put human concerns on the top priority, enhance the coordinated development between rail microcenters and urban functions, and strengthen its own facilitation. 展开更多
