摘　　要：由于速度、票价、合理运距等技术经济特征的差异,高速铁路和普通铁路可以反映不同功效层级的空间运输联系,并对国土空间结构重塑产生影响。本文基于铁路列车时刻表数据,采用客流联系强度模型,研究了基于高铁与普铁服务的差异化空间级联系统秩序,比较了两者对功效空间的区域整合效应。研究结论为:相较普铁而言,高铁的空间布局与全国经济社会发展梯度格局更一致,距离衰减效应更显著,在600 km范围内最具优势;高铁与普铁优势城市分别集中在长江以南和以北,考虑旅客运输需求后显示普铁服务更为均衡。进一步分析发现,在技术经济优势、高铁与普铁竞争以及网络布局影响下,高铁功效空间区域整合呈现出显著的两极分化态势,以邻近区域集聚形态为主,普铁则形成了宏观尺度的南北向和东西向跨区域廊道集聚形态,二者对功效空间区域整合亦分别呈现出多中心等级化与多板块均衡化组织模式。There are differences between high-speed rail and conventional rail in technical and economic characteristics such as speed,ticket price and reasonable transport distance.Therefore,they can reflect spatial traffic links at different scales,which have important impact on the reshaping of territorial space.Using train timetable data,this paper analyzes the differential spatial cascading system order of high-speed rail and conventional rail service,and compares the regional integration effect of these two rail modes on the spatial cascading system.The results show that,compared with conventional rail,the spatial layout of high-speed rail is more consistent with the gradient pattern of national economic and social development.The distance decay effect of traffic flows by high-speed rail is more obvious,with an advantage over conventional rail for journeys within 600 km.The advantaged cities of high-speed rail and conventional rail are spatially concentrated to the south and north of the Yangtze River respectively.The conventional rail service presents a more balanced distribution considering the demand of passenger transport.Further analysis shows that,under the influence of technical and economic advantages,competition between high-speed rail and conventional rail,and the network spatial layout,the regional integration effect of high-speed rail on efficiency space shows a significant polarization,with the neighboring regional agglomeration as the main form,while conventional rail has formed cross-regional corridor agglomeration along the north-south direction and east-west direction at the macro level.The regional integration model of highspeed rail and conventional rail also presents the characteristics of multi-center grading and multi-plate equalization respectively.
