【摘要】：从可达性的视角采用平均旅行时间、经济潜力、日常可达性等指标对河南"米"字形高速铁路网构建对各地市省内和省际可达性及城市空间格局的影响进行分析发现,(1)"米"字形高速铁路网有助于各地市省内和省际可达性水平提升,郑州的极化与集聚效应进一步增强,边界城市的交通边缘化状况明显改善,"米"字形城镇发展轴带正在形成;(2)各地市省内和省际经济潜力大幅度提升,位置居中的高铁沿线城市省内区位优势显著,边界高铁沿线城市在省际联系中的门户区位优势显现;(3)以郑州中心的0.5 h核心圈、1 h紧密圈正在形成,"同城效应"显现,各地市省际2 h交流圈大幅度拓展,以郑州为中心的1.5 h省际合作圈即将形成。高铁网的构建将成为河南城市空间格局演变的重要推动因素和空间结构优化的基础支撑条件。
[Abstract]:From the perspective of accessibility, using the average travel time, economic potential,By analyzing the influence of daily accessibility and other indexes on the accessibility and urban spatial pattern of Henan "m" zigzag high-speed railway network, it is found that the "meter" zigzag high-speed railway network is helpful to the provincial and urban spatial patterns.Promotion of interprovincial accessibility,The polarization and agglomeration effect in Zhengzhou has been further strengthened, the traffic marginalization in border cities has been improved markedly, and the "meter" zigzag urban development axis is forming in the area of "Guanzao 2".) the economic potential of various prefectures and cities has been greatly enhanced both within and between provinces.The central city along the high-speed rail line has significant location advantage in the province, and the portal location advantage of the borderline high-speed railway city in the inter-provincial connection is obvious. (3) the close circle of 0.5 h core circle in the center of Zhengzhou is formed, and the "same city effect" appears.The inter-provincial communication circle of each prefecture and city has been greatly expanded in 2 hours, and the 1.5 h inter-provincial cooperation circle with Zhengzhou as the center is coming into being.The construction of high-speed rail network will become an important driving factor for the evolution of urban spatial pattern in Henan Province and the basic supporting condition for the optimization of spatial structure.
