| 摘 要： | 基于2018年高铁网络OD数据,运用社会网络分析方法从高铁网络、城市节点等方面探讨中国城市高铁网络结构特征及其地域组织模式,结果表明：①中国高铁网络整体较为松散,东北地区网络密度最高,东部和中部地区作为整体网络的中介作用明显;②重要高铁线路的“廊道效应”突出,中心度呈现出以京广、京沪和沪昆高铁组成的“三角旗状”空间格局并向两侧城市呈不规则递减的态势;③多层级网络识别出紧密关联高铁线路和四横四纵向八横八纵格局的转变;④高铁网络的地域组织形式表现为点-轴串珠模式、双核组团模式和极核模式,高铁网络的完善使组织模式由单核趋向于网络化转变。

| Abstract: | High-speed rail is an important part of modern transport infrastructure. It has an important impact on the flow of production factors, the expansion of urban space, and the reconstruction of regional spatial structure. Based on the O-D data of high-speed rail network in 2018, the social network analysis is used to discuss the structural characteristics of high-speed rail network and other organizational modes from HSR network and urban nodes. The results show that: 1) China's high-speed rail network has experienced four stages of germination, start-up, tortuous development and prosperity. China's high-speed rail network is relatively loose overall, the northeast region has the highest network density and western network density is sparse. High-speed rail links between the western region and the northeastern region are sparse. The intermediary role of the central and eastern regions in the overall network is obvious; 2) The “corridor effect” of the important high-speed rail channel is remarkable. The area along the Beijing-Shanghai high-speed railway and the Beijing-Guangzhou high-speed railway has become hot spot with high central value region. On the whole, it has a “triangular flag” composed of Beijing-Guangzhou, Beijing-Shanghai and Shanghai-Kunming high-speed railways. Spatial pattern and the trend of decreasing toward the cities on both sides. The centrality of the intermediary shows that the random distribution of the central hub city can better play a cohesive role; 3) The first-level high-speed rail network shows the high-speed rail corridors closely related to Shanghai-Nanjing Intercity, Beijing-Tianjin Intercity and Wuhan-Guangzhou High-speed Railway. The second-level network basically reveals the road network planning of China's high-speed railways and the provincial cities in the high-speed rail network as a prominent intermediary role; The third level identifies the trend of the high-speed rail network from four horizontal and vertical expand to eight horizontal and eight vertical. The fourth level of China's high-speed rail network shows overall spatial network details; 4) The territorial organization models of high-speed railway network is characterized by point-axis beading mode, dual-core grouping mode and polar core model, the perfection of the high-speed railway networkhas transformed the organizational model from a single core to a network. |
