摘要
针对我国关于可达性及经济联系格局的高铁研究在省域层面上的空缺,本文选取加权平均旅行时间测算湖北省各地级市的可达性,运用引力模型计算城市经济联系强度,利用ArcGIS系统直观分析了省内区域空间可达格局和经济联系的变化情况,并进行空间自相关分析。研究结果表明,高铁显著地压缩了湖北地区的地理时空,提高了可达性水平,有利于武汉城市圈向西北扩展。高铁的出现加强了空间集聚效应,一定程度上弱化了距离衰退效应对经济联系格局的影响,但集聚效果集中在以武汉市为中心沿高铁方向轴向延伸的地区,边缘地区与中心的差距扩大。
Reviewing domestic studies, we found that most scholars focus on the influence of high-speed railway along the rail. Based on weighted average travel time, economic gravitation model and ArcGIS system, in this paper, we take the date of train timetable in Hubei province as study objects to calculate the rational accessibility and provincial economic linkage. In the end, spatial autocorrelation is being analyzed.Results show that high-speed railways promote spatial agglomeration, weaken the effect of distance and are conducive to the expansion to northwest in Wuhan city circle. But it exacerbates the disparity between the edge cities and the central cities. The study is helpful to clarify the temporal and spatial laws of economic development among provincial cities, and provide a reference for the further development of regional highways.
