高速铁路对沿线地区城市腹地的影响研究——以皖北地区为例

城市腹地一直是城市区域研究的热点,特别是外部交通环境的改变将对原有的城市腹地范围产生巨大的影响。近年来国内的高铁建设极大地改变了沿线地区城市腹地的格局。基于场强模型研究了京沪、京福高铁对皖北地区城市腹地的影响。首先,利用城市综合规模指数和交通时间成本对传统场强模型中的城市规模和距离因子进行了修正:随后在GIS技术支持下利用修正的场强模型计算了皖北地区在高铁通车前后的城市腹地范围,并分析其格局变化的特征。最后探讨高铁对沿线地区城市腹地影响的一般规律。

A Study on the Influence of High-speed Railways on Urban Hinterland: The Case of North Anhui

Urban hinterland has always been a spotlight in regional researches. Changes in a city’s external traffic conditions,such as the construction of high-speed rail(HSR),usually have a huge impact on urban hinterland.Based on the field-strength model,this paper discusses the influence of Beijing-Shanghai and Beijing-Fuzhou HSR on urban hinterland in North Anhui.It first employs composite indicator index and time cost for transportation,instead of the city scale and the distance factor,used in the traditional field-strength model.It then calculates the changes of urban hinterland with modified field-strength model for the scenarios of both with and without HSR,using GIS technology.Furthermore,the overal impact of HSR on urban hinterland along the HSR line is also analyzed in the paper.
