摘　　要： 空间运输联系反映地理单元间的经济联系,与城镇化进程和区域发展格局息息相关。随着经济发展和城镇化水平的提高,省内客运联系增长速度显著快于省际,省域客运联系呈现内聚化态势;从各区域变化幅度看,内聚化态势围绕三大核心城市群由内而外逐步加强,并呈现较大的南北差异。省际客运联系呈现以京津冀、长三角、珠三角为核心的中心—外围结构,从发展态势看,沿海城市群的极化效应进一步凸显,中西部区域区内联系加强态势初步显现。研究显示:现状城镇空间不平衡特征仍较为突出,尤其南北分化问题凸显;未来城镇空间布局需突出沿海城镇空间的再平衡、促进中西部城镇空间的多中心集聚和加强南北区域协作。 Transportation demand are closely related to urbanization process and regional development, which reflects the economic linkages among the geography units. With the economic development and ur-banization, the demand increase for intra-province transportation is significantly faster than the demand for inter-province transportation. The inter-regional passenger transportation demand shows a trend of cohe-sion. By reviewing the changes in different ranges, it is clear that the trend of cohesion, encompassing three core clusters of metropolitan areas, is gradually strengthened from inside to outside with a large dif-ference between the north and south. The inter-provincial passenger transportation demand presents a cen-ter-periphery structure with the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta as the core. From the development trend, the polarization effect of the coastal urban clusters is further highlight-ed, and the connection of central and western regions becomes evidently closer. The results show that the urban spatial imbalance is still prominent, especially between the north and south. Specifically, the rebal-ance on costal urban space should be highlighted, multi-center agglomeration of urban space in central and western regions should be promoted, and north-south regional cooperation should be enhanced in the fu-ture urban and rural land use development.
