高速铁路网络协同发展对城市群空间重构的分形研究
Fractal Study on Spatial Reconstruction of Urban Agglomerations under the Coordinated Development of High Speed Railway Networks
摘要
Abstract
The construction and development of high speed railways have driven the coordinated development and spatial pattern transformation of urban agglomerations.To explore the impact of the coordinated development of high speed railway networks on the spatial structure of urban agglomerations,based on fractal theory,this paper utilized the box dimension and length-radius dimension to describe the coverage uniformity and complexity of high speed railway networks.The Hausdorff dimension was combined with Zipf's law to analyze the size sequence structure of urban agglomerations.The correlation dimension and aggregation dimension were used to analyze the spatial structure relevance and aggregation of urban agglomerations.Taking five urban agglomerations with well-developed high speed railway networks as examples,this paper compared and analyzed the evolution of their spatial structure before and after the introduction of high speed railways.The results show that the coverage uniformity of the high speed railway network is not high,and some areas have good accessibility.After the completion of the high speed railway,the accessibility of urban agglomerations such as the Liaozhongnan city group has been significantly improved,and the connections between cities have become closer.The economic effects of high speed railways have promoted the coordinated development of urban agglomerations.Urban agglomerations such as the Guanzhong plain city group show a trend towards agglomeration distribution.Therefore,it is necessary to strengthen the construction of a rapid transportation system based on high speed railways and supplemented by intercity railways.关键词
