中文摘要:
      选择京石客运专线的7个站点城市作为研究对象,按照其城市规模将研究区域分为3个层次,利用有利平均旅行时间模型和潜能模型来计算京石客专沿线站点城市的可达性值。通过建成前和建成后的可达性变化,分析京石客运专线的修建对沿线站点城市可达性的影响。研究表明:京石客运专线修建后对7个站点城市的可达性均有提升,沿线“廊道效应”有所增强;两个模型指标因考虑因素不同,城市可达性的提升程度略有差异;京石客运专线开通后,经济要素沿线路集散,使得3个层次城市之间的梯度差不断减小,区域一体化趋势更加明显。
英文摘要:
      Altogether seven cities along the Beijing Shijiazhuang Passenger Dedicated Railway are selected as the objects of our research in the present paper, which are divided into three levels according to the size of them, upon the basis of which both the favorable average travel time model and the potential capability model are used to calculate the accessibility values of the cities along the Beijing Shijiazhuang Passenger Dedicated Railway. Through comparing the changes in the accessibility values before and after the completion of the high speed railway, the impact of the Beijing Shijiazhuang Passenger Dedicated Railway on the accessibility of the cities along the railway are analyzed. The research shows that after the construction of the Beijing Shijiazhuang Passenger Dedicated Railway, the accessibility of all the seven station cities is improved, with the "corridor effect" along the railway enhanced to some extent. Because of different considerations for the two models, the degree of the improvement of urban accessibility is slightly different. After the Beijing Shijiazhuang Passenger Dedicated Railway is put into operation, the economic factors are distributed along the railway, which makes the gradient difference among the three levels of cities decrease continuously, with the trend of the regional integration more and more obvious.
