火车站、机场和港口视角下各节点城市的空间联系强度地域差异性和两极化现象

Under the railway station, the airport and the port city of perspective space of each node link regional differences strength and polarization of obvious, basically showing ≥ airport railway station> serial port. Yangtze River Economic Belt under three perspectives intensity spatial connection between nodes in the city showed a contiguous distribution of multi-core and a combination of momentum, and the whole eastern region of space to contact the strongest, strong central region, the western region of the weakest, east, , the integrated development of the western traffic imbalance.

The regional differences and polarization of spatial contact intensity of each node city under the perspective of railway station, airport and port are obvious, and the sequence of railway stations and airports is basically presented. Under the three perspectives, the spatial contact intensity between the node cities of the Yangtze River Economic Belt shows the combined situation of multi-core and continuous distribution, and the overall spatial link in the eastern region is the strongest, the central region is stronger, the western region is the weakest, and the comprehensive traffic development of the east, middle and west is unbalanced.

From the perspective of railway station, airport and port, the spatial connection intensity of each node city has obvious regional difference and polarization, basically showing the sequence of railway station ≥ Airport > port. Under the three perspectives, the spatial connection strength of each node city in the Yangtze River economic belt shows the trend of combining multi-core and contiguous distribution, and the overall spatial connection of the eastern region is the strongest, the central region is stronger, the western region is the weakest, and the comprehensive transportation development of the eastern, central and western regions is unbalanced.
