基于引力模型的山东省城市空间格局研究

Research on spatial patterns of cities in Shandong Province based on gravity model

以引力理论为基础,选择具有针对性的指标,运用引力模型和断裂点公式,计算山东省17个城市之间的引力值和断裂点位置,以此为依据研究山东省城市空间格局特征及演化过程。结果表明:山东省呈"双核心"的总体格局,区域性的城镇组群逐渐形成,边缘地区城市受屏蔽作用的影响日益明显。最后对山东省城市空间优化提出了有针对性的建议。

Based on the gravitation theory, by choosing some specific targets, the paper uses the gravity formula and the break-point formula to get the gravity value and location of the breaking point among 17 cities in Shandong Province, which are used as a basis to study the characteristics and evolution of the cities＇ spatial patterns in Shandong. The results show that the overall pattern of Shandong Province is ＂dual core＂, that regional urban groups are gradually formed and that the influence of shielding effect becomes more and more obvious in marginal areas. Finally, some recommendations are presented to optimize the layout of urban space in Shandong Province.
