摘要： 由于城市群的城镇布局、发展阶段不同，建设的高速铁路技术标准也各异，因此其带来的可 达性变化以及对城市群空间格局的影响也可能存在差异。基于可达性模型和场强模型，分析高速铁 路建设对中国不同城市群产生的影响。结果表明：高速铁路能够有效改善城市群可达性，但其技术 标准和设站模式会影响可达性改善的效果；只有高辐射能级的城市才能依托高速铁路提升对外辐射 作用，低辐射能级城市在高铁开通前后对外辐射强度的提升并不明显。根据上述结果，在高速铁 路网络布局、设站间距等方面提出相应建议，为城市群高速铁路网完善提供参考。

Abstract： Due to the different urban layout and development stages of urban clusters, the technical standards of high-speed railway construction are also different, so the accessibility changes and the impact on the spatial layout of urban clusters may also be different. Based on the accessibility model and spatial field model, this paper discusses the impact of high-speed railway construction on different city clusters in China. The results show that high-speed railway can effectively improve the accessibility of city clusters, but the effect of improvement is closely influenced by technical standards and stations' location within the city and in the city clusters. Only higher-tier cities can rely on high-speed railway to enhance impact area, other than in the lower-tier cities. According to the above results, the paper provides suggestions on how to improve high-speed railway network in city clusters in network layout and station spacing.
