【摘要】：目前,京津冀协同发展已经上升为国家战略,而交通一体化、生态环境保护、产业对接协作成为京津冀协同发展的三个突破口,其中交通一体化作为基础条件应当先行启动,率先突破,特别是区域铁路网络一体化是非常重要的一环。文章基于非线性分形模型,测算京津冀铁路网络均匀度和复杂度,考察铁路规模与经济增长之间的协调关系。结果发现,尽管与长江三角洲和珠江三角洲相比,京津冀铁路拥有较高的网络密度,但存在过度集中于北京枢纽的结构性问题,加之近十年来京津冀铁路规模扩张速度低于经济增长速度,已经出现了较为明显的门限作用。为更好地实现京津冀优势互补,促进并带动环渤海经济区以及北方腹地的发展,未来京津冀铁路网络建设必须以协调发展为前提,建设并调整铁路网络布局,将以北京为核心的放射型铁路网络转换为环放结合的网络形态,打造京津双核铁路枢纽,打破区域内铁路网络分布不均衡的现状,缓解首都过境交通压力,促进京津冀铁路网络布局转型升级。
[Abstract]:At present, the coordinated development of Beijing-Tianjin-Hebei has become a national strategy, and transportation integration, ecological environment protection and industrial docking and coordination have become the three breakthrough points of Beijing-Tianjin-Hebei coordinated development, among which transportation integration should be started as a basic condition. The first breakthrough, especially the integration of regional railway network is a very important link. Based on nonlinear fractal model, this paper calculates the uniformity and complexity of Beijing-Tianjin-Hebei railway network, and investigates the coordination relationship between railway scale and economic growth. The results show that although the Beijing-Tianjin-Hebei railway has a high network density compared with the Yangtze River Delta and the Pearl River Delta, there is a structural problem of excessive concentration in the Beijing hub. In addition, the expansion speed of Beijing-Tianjin-Hebei railway is lower than that of economic growth in recent ten years. In order to better realize the complementary advantages of Beijing-Tianjin-Hebei, and to promote and promote the development of the economic zone around the Bohai Sea and the hinterland of the north, the future construction of the Beijing-Tianjin-Hebei railway network must take the coordinated development as the premise to construct and adjust the layout of the railway network. The radiation-type railway network with Beijing as the core will be transformed into the network form of the combination of ring and release, to build the Beijing-Tianjin dual-core railway hub, to break the unbalanced distribution of the railway network in the region, and to ease the pressure of transit traffic in the capital. Promote the Beijing-Tianjin-Hebei railway network layout transformation and upgrading.
