摘要
首次涉足中国城市密集区高铁、城际铁路和地铁(合称"三铁")"轴—辐"式交通组织的空间效应问题域。采用网络分析法对武汉城市圈"三铁"交通枢纽服务范围进行分析,其空间布局呈圈层状。分别从整体配置、主要站点和节点城市对三个层次空间效应进行分析,发现高铁促进武汉城市圈与其他城市群之间的联系,催生出新的高铁城,城铁加速卫星城与主城区之间的协作,地铁在整合各个功能区的同时刺激郊区城镇化。"三铁"轴线和枢纽对城市圈人口集聚、城镇建设用地扩张和要素流动等产生不同程度的影响,其空间效应主要集中在中心节点城市,沿交通网络分层次渗透衍射到次级节点城市,进而覆盖整个武汉城市圈,并有助于保持极化与扩散兼有的空间经济格局。
The spatial effects problem domain which about the＂axle-spoke＂like transport system made up of high-speed railways, intercity railways and subways in Chinese city compact district is initially discussed in this paper. The rail rapid transit system helps the reconstruction of the spatial structure of Wuhan metropolitan area, its impact on this area lies in three levels, that is, between the urban agglomerations, between the central city and the satellite cities, and the inner side of the central city. The network analyst method is applied to measure the service scopes of the rail rapid transit stations in Wuhan metropolitan area. Then the results are interpreted from the perspective of whole area, different types of stations as well as node cities according to the three levels mentioned above. It shows that the high-speed railways mainly help the connections between the Wuhan metropolitan area and other urban agglomerations, the new cities are also grow around the high-speed railway stations; the intercity railways accelerate the cooperation among the satellite cities and the central city; the subway integrates the different function districts of the central city, and stimulates the urbanization of suburb at the same time. Both the lines and stations of the rapid rail transit exert different degree influence on population agglomeration, urban construction land exploration and factor flow, the spatial effect mostly concentrated in central node cities, then seep through the transportation network according to levels to the next degree node cities and towns, the whole Wuhan metropolitan area is covered at last. And the construction of the rail rapid transit system will be helpful to keep the spatial economic pattern which characterizes both polarization and diffusion in a fairly long time.
