高铁班次统计视角下的城市等级和空间联系格局分析

Analysis of the City Rank and Spatial Contact Pattern Based on High-speed Rail Frequency Statistics

高铁的发展与城市密切相关,为了解中国高铁城市的体系特征,以高铁班次为基础,利用热点分析、聚类分析、相关分析、空间统计等空间分析方法对中国高铁城市进行分析。研究表明,高铁城市空间分布不均衡,集中分布在经济较为发达、人口较为密集的城市群内,城市等级呈明显的金字塔特征。全国性高铁中心城市与其他城市之间的联系具有一定的方向性,联系密度和联系强度差异较大,集聚特征较为明显。

The development of High-speed Rail is closely re- lated to the city. Based on the data of high-speed rail, hot spot analysis, clustering analysis, correlation analysis, spa- tial statistical analysis methods are applied to analyze the system characters of China＇s high-speed rail cities. Results show that the apatial distribution of cities is uneven, they are mainly distributed in a high economic level and more densely populated territories urban cluster. The city rank has an ob- vious pyramid characteristic. The link between central cities and other cities have a certain direction, while the contact density and strength are different and agglomeration features are more obvious.
