The stable development of transportation network helps to enhance system resilience and reliability.Based on complex network theory,a weighted network model of Xi'an Metro morning and evening peak passenger flow is constructed using Space L network modeling method,and the temporal and spatial evolution characteristics of structural attributes and node center attributes of Xi'an Metro network are evaluated by combining the improved local indexes and global system with the evolution characteristics of the complex network.The results are found:1)The connectivity and resilience of the Xi'an Metro network has improved significantly over time.2)The network density increases,which improves the accessibility is improved,however,the importance of individual stations is polarized,and a few stations have high node centrality,and it is expected that the opening of the new line loop can further improve the network resilience and service capacity,and better relieve congestion.3)As the period and network complexity increase,the overall trend of node median centrality tends to the right long-tailed normal distribution,and the Xi'an Metro network belongs to the benign development.4)With the expansion of the network,Xi'an Metro high closeness station is less and less,on the contrary,low closeness station accounted for a larger and larger proportion of the overall network of the center of gravity to the south of the evolution trend.
