中国铁路客运流的网络格局与空间特征研究

Network Pattern and Spatial Characteristics of Railway Passenger Flow in China

铁路客运流是我国交通体系的关键领域,研究综合多种方法对我国铁路客运流的网络格局进行探析,通过细化铁路列车的类型,展现不同铁路类型下的城市网络格局与空间特征。研究表明,北京、广州、上海、武汉和西安等是多个类型铁路客运网络的中心城市,网络化联系的重心呈现从北向南扩展的态势;普速网的分布集中于东北地区,高铁网和动车网集中于胡焕庸线以东,快速网和特快网覆盖范围最广;长三角城市群与长江中游城市群的首位联系规模最大,网络化联系的空间指向性明显以及中介枢纽的作用显著;铁路客运流网络呈现出空间跳跃、等级体系、多中心发展,以及空间选择性的特征。最后在上述研究的基础上为我国的空间发展提出建议。

Railway passenger flow is a key area in China's transportation system.A comprehensive study of various methods is applied to analyze the network pattern of China's railway passenger flow.By dividing the differenttypes of passenger trains,the study showsthe urban network pattern and spatial characteristics of passenger trains.Firstly,Beijing,Guangzhou,Shanghai,Wuhan,and Xi'an are the central cities of many types of passenger train networks.The multi-center of network connection presents a trend of expanding from north to south.Secondly,the ordinary train network is distributed in the northeast region,the high-speed railway network in the east of the Hu Line,and the rapid and express networks have the widest coverage.Thirdly,the Yangtze River Delta urban agglomerations andthe urban agglomeration in the middle reaches of the Yangtze River have the largest scale contact.The space centripetal force of network connection and the role as an intermediary hub are significant.Fourthly,the railway passenger network presents the characteristics of space leaping,hierarchical system,multi-center development and spatial selectivity.Finally,based on the above research,suggestions are made for our country's spatial development of railway passenger flow.
