高铁流视角下长三角城市网络结构时空演变研究
Research on the Spatio-temporal Evolution of Urban Network Structure in the Yangtze River Delta from the Perspective of High-speed Rail Flow
摘要
Abstract
The growth of high-speed rail has compressed the region's spatio-temporal distances significantly,and altered the spatial pattern of urban network.High-speed rail flow has grown to be a significant perspective for urban network studies.Taking the first year of the 12th,14th Five-Year Plans as the research node,we used social network analysis method to study the spatio-temporal evolution features of urban network structure in the Yangtze River Delta region from the perspective of high-speed rail flow.The results indicate that①the Yangtze River Delta has essentially attained full coverage of high-speed rail cities,the network scale has been steadily increased,the network density has been improved in a systematic manner,and the intra-provincial and inter-provincial links have attained a high level.②The high-speed rail network has gone through three stages of development,such as childhood,adolescence,and adulthood,indicating a multi-center and balanced multi-polar network model with the province capital as its core.The degree of network agglomeration has weakened and tended to remain steady.③In the Yangtze River Delta,there is a clear tendency toward dense urban connectivity in the high-speed rail network.Three stable triangles have been established by the Shanghai-Nanjing,Shanghai-Hangzhou,and Nanjing-Hangzhou intercity rail.The axial connection form has been replaced with the more intricate network structure.关键词
