摘　　要：中小城市是我国推进新型城镇化建设的主战场,基于县级单元尺度定量计算城际客运联系,研究城际客运联系网络空间结构特征,从而加强交通基础设施建设并提供高效旅客运输服务十分必要。利用高速公路联网收费系统客车通行OD数据,计算并构建基于县级单元的城际客运联系网络。围绕城际客运主要联系方向、联系规模、联系密切程度及空间联系模式,建立城际客运联系中心等级结构、客运联系强度结构、首位客运联系紧密度、客运联系紧密度结构、客运联系组团分区结构等分析维度,刻画城际客运联系网络状态特征。以辽宁省高速公路客车联系网络为例进行实证分析,可以发现城际客运联系主要受到市级行政区划边界约束,组团分区格局基本契合全省三大经济区域范围。城际客运联系网络空间分析对于优化全省城际客运服务网络,明确辽中南城市群范围,促进全省三大经济区域协调发展等具有重要意义。Small and medium-sized cities will become the main battlefield in new urbanization con-struction in China. It is necessary to quantitatively calculate intercity passenger linkage and research in-tercity passenger linkage network feature based on county units in order to strengthen transportation in-frastructure construction and provide effective passenger transport services. With the bus traffic OD datain the expressway toll system, intercity passenger transport network was established based on the countyunits. Focusing on the main direction, scale, intensity and spatial linkage patterns of the intercity passen-ger transport linkage, the analysis dimensions such as the grade structure of intercity passenger transportlinkage centers, the linkage strength structure of passenger transport, the first close passenger transportlinkage, the closeness structure of passenger transport linkage, the passenger transport linkage district and so on were established to describe the state features of intercity passenger transport linkage network.Taking the intercity passenger transport linkage network on the expressway in Liaoning Province as anexample, it can be found that intercity passenger linkage is mainly affected by the constraints of munici-pal administrative boundary, district pattern basically fits three economic areas in Liaoning Province.The analysis of passenger transport linkage network has vital significance to optimize the intercity pas-senger transport service network, define boundaries of central-southern Liaoning and promote coordinat-ed development of the three economic areas in Liaoning Province.
