摘　　要：高速铁路作为新兴的交通运输方式,对沿线城市及区域的可达性格局和经济联系空间结构有重要影响。在京津冀协同发展大背景下,基于2022年北京与张家口将携手举办冬奥会这一机遇,北京至张家口交通运输方式正发生着革命性的变革。以京张高铁为例,从微观尺度出发,以加权平均旅行时间分析沿线各区县的可达性水平变化,运用引力模型探寻各区县经济联系空间结构的演化,结果表明:京张高铁的开通将在很大程度上优化沿线区县的可达性水平;沿线区县之间的经济联系将进一步加大,经济格局呈现“多中心化”趋势,空间格局则呈现“一轴多极”模式;区域的主要经济联系方向趋向于“地域临近指向性”,空间紧邻效应明显。As a new way of transportation,high-speed railway has a great influence on the accessibility and the spatial structure of economic relations of cities and regions along the railway.Under the background of coordinated development of the Beijing-Tianjin-Hebei region,the transportation mode from Beijing to Zhangjiakou is undergoing a revolutionary change on account of the opportunity that Beijing and Zhangjiakou will jointly host the Olympic in 2022.Taking the Beijing-Zhangjiakou high-speed railway as an example,this paper analyzes the change of accessibility of each district and county along the Beijing-Zhangjiakou high-speed railway from the micro scale with the weighted average travel time,and explores the evolution of the spatial structure of economic connection of each district and county by employing the gravity model.The results show that the opening of Beijing-Zhangjiakou high-speed railway will optimize the accessibility level of the counties along the route to a large degree.At the same time,the economic relations among the regions and counties along the route will be further enlarged;the economic pattern will show a“multi-centralization”trend;the spatial pattern will reveal a mode of“one-axis multi-pole”;the main economic connection of this region tends to be“regional proximity directivity”,and the spatial proximity effect is obvious.
