高速公路对城市群空间相互作用的影响研究——以山东半岛城市群为例

高速公路的出现和发展,深刻影响着城市群内空间的相互作用,研究这种作用则有助于把握城市群空间结构发展演化的规律和机制.以山东半岛城市群为例,运用引力模型、边界模型、高速公路空间袭夺效应模型和城市群空间紧凑度模型进行计算和分析.结果发现,城市群内空间引力的变化与高速公路密度水平紧密相关,高速公路建设和运营影响着区域城市群内各城市之间对空间的争夺,并产生不同的袭夺效应,城市群空间紧凑度也提高.同时,提出了"高速公路空间袭夺效应"的概念及公式,以定量分析高速公路在某时间段内对两城市之间空间袭夺所发挥的作用.

IMPACT OF HIGHWAY ON URBAN AGGLOMERATION SPATIAL INTERACTION: A CASE OF SHANDONG PENINSULA URBAN AGGLOMERATION

The appearance and development of highway affected Urban Agglomeration Spatial Interaction deeply. The research about it can help to grasp the development evolution and the mechanism of the spatial structure of urban agglomeration. Took Shandong peninsula urban agglomerations for example; make use of gravity model, the boundary model, capture effect of space of highway model and urban agglomeration spatial compactness model to calculate and analysis. The results showed that the changes of space gravity inside urban agglomeration were closely connected with the density of highway; the operation and construction of highway impacted on the competition for space between cities, different capture effects turned up at same time; urban agglomeration spatial compactness was also raised. Besides, capture effect of space of highway was proposed, in order to qualitative analysis the effect of which the highway impacted on the compaction for space between cities in a certain period of time.
