【摘要】：高铁时代,铁路网的完善与高速铁路建设对沿线中心城市可达性变化产生重要影响。选取2008年、2015年及2025年作为时间断面,以甘肃省14个地级市及全国交通数据为基础,应用可达性技术分析方法对高铁通车前后沿线中心城市的交通可达性演变进行研究。研究结果表明:2025年高铁时代,中心城市之间的交通可达性水平显著提高;沿线中心城市对周围地区辐射影响增强;宝兰客运专线建成使得天水至西安段交通可达性增幅超两倍;兰渝高铁的建成缩短甘肃省至中部及南方大部分省份时间,实现地理时空有效收敛。"一带一路"背景下,研究可达性演变有利于廓清各地市空间发展导向,明晰省内各地区和省际地区间的联系,为区域空间发展战略的制定提供参考。
[Abstract]:In the era of high-speed railway, the improvement of railway network and the construction of high-speed railway have an important influence on the change of accessibility of central cities along the route. Taking 2008, 2015 and 2025 as the time section, based on the traffic data of 14 prefectural cities and the whole country in Gansu Province, the traffic accessibility evolution of the central cities along the route before and after the opening of high-speed railway was studied by using the reachability analysis method. The results show that in 2025, the level of traffic accessibility between central cities was significantly improved, the radiation effect of central cities on the surrounding areas was enhanced, and the traffic accessibility of Tianshui to Xi'an section was increased by more than twice as much as the completion of Baolan passenger dedicated line. The completion of the Lanyu High Speed Railway shortens the time between Gansu Province and most of the provinces in the central and southern parts of the country, and realizes the effective convergence of geographical time and space. " Under the background of Belt and Road, studying the evolution of reachability is helpful to clarify the spatial development orientation of different cities, to clarify the relationship between different regions and interprovincial regions, and to provide a reference for the formulation of regional spatial development strategy.
