【摘要】：不同层次和范围的交通圈是经济社会空间组织的重要依据。本文运用网络分析与成本加权距离集成算法,设计了定量界定交通圈的技术路线。在此基础上,以通勤便捷为目标,提出1小时交通圈内部圈层的划分方法和轨道交通服务指数,据此分析了北京1小时交通圈的内部层次和结构特征;以经济分工协调为目标,基于时空距离与交通方式,划分北京一日交通圈的圈层,并提出交通廊道的界定方法,据此探讨了北京一日交通圈内部各廊道地区的空间范围与经济基础。结果显示:北京市等时间交通圈的形态受高速交通影响较大,具有显著的偏向式延伸特点,并在边缘地带形成少量"岛";轨道交通对北京市1小时交通圈的支撑力度较弱,未来应加强重点方向的轨道交通建设;根据各廊道的具体情况,京津廊道、京唐廊道是京津冀协同发展的重要载体,京石廊道宜定位为承接北京地区产业转移的重点地区,京承廊道与京张廊道则适宜发展生态型经济。
[Abstract]:Traffic circle of different levels and ranges is the important basis of economic and social spatial organization. This paper uses network analysis and cost weighted distance integration algorithm to design the technical route of quantificationally defining traffic circle. On this basis, it aims at convenient commuting. This paper puts forward the method of dividing the inner circle of one hour traffic circle and the service index of rail transit, according to which the inner layer and structure characteristics of Beijing 1 hour traffic circle are analyzed, and the coordination of economic division of labor is taken as the goal, based on the space-time distance and the mode of transportation. Divide the traffic circle of Beijing on one day, and put forward the method of defining the traffic corridor, Based on this, the spatial range and economic basis of each corridor area inside the Beijing daily traffic circle are discussed. The results show that the shape of the traffic circle at the same time in Beijing is greatly affected by the high-speed traffic, and has the characteristic of obvious bias extension. A small number of "islands" are formed in the fringe zone; the rail transit has a weak support for the one-hour traffic circle in Beijing, so it is necessary to strengthen the construction of rail transit in key directions in the future; according to the specific conditions of each corridor, the Beijing-Tianjin corridor, The Beijing-Tang corridor is an important carrier for the coordinated development of Beijing-Tianjin-Hebei. The Beijing-stone corridor should be positioned as the key area to undertake the industrial transfer in Beijing, while the Beijing-Cheng-corridor and the Beijing-Zhang-corridor are suitable for the development of ecotypic economy.
