区域一体化视角下长三角高铁网络结构特征研究
Study on the structural characteristics of the Yangtze River Delta high-speed rail network from the perspective of regional integration
摘要
Abstract
Taking the 40 prefecture-level cities in the Yangtze River Delta region as the research unit,a 40×40 matrix of daily high-speed rail operation frequency between O-D cities is constructed from the perspective of high-speed rail flow.Using the method of social network,the spatial structure characteristics of high-speed rail net-work in the Yangtze River Delta region are analyzed.The results show that the high-speed rail network flow in the Yangtze River Delta region is characterized by the directionality of regional core cities and provincial capitals,and the overall network function is more complete.One city,Shanghai,and two provinces,Jiangsu and Zhe-jiang,forming the core gathering area of high-speed rail flow.Shanghai,Hangzhou and Nanjing play important roles in the regional high-speed rail network,with the functions of agglomeration,radiation and bridge,and the core node city status is prominent.Wuxi,Suzhou,Changzhou,Hefei and Zhenjiang,with strong accessibility to other nodes,also have certain intermediary functions,and are important nodes of the regional high-speed rail network.Xuzhou,Ningbo,Jiaxing,Wenzhou,Wuhu and Yangzhou,which have certain agglomeration or radia-tion function in the regional HSR flow network,are the sub-important nodes of the regional HSR network.Over-all,the spatial structure of the Yangtze River Delta regional high-speed rail network presents the characteristics of polycentricity,prominent status of core cities,and obvious differences in the hierarchical structure of node cit-ies.关键词
