基于引力模型的山西省城市空间相互作用研究

Research on Urban Spatial Interaction in Shanxi Province Based on Gravity Model

研究城市间的相互作用水平,有助于优化全省空间资源配置和城乡空间布局,促进全省城市转型和城镇化健康发展。本研究引入引力模型来计算山西省11个市的空间引力值,并根据断裂点公式计算的结果分析山西省城市空间相互作用的水平和空间格局。研究结果表明:太原市核心地位显著,高首位度特征突出;以省会太原市为核心的山西省中部城市群形成高度关联区域;山西省城市发展偏心化。最后,以提高城市综合实力、优化交通网络和区域对接关联水平为出发点,提出加强山西省城市间相互作用水平的对策建议,以期提高山西省城镇化水平和质量,优化山西省城镇化空间布局,增强各级城镇活力和竞争力。

Studying the interaction level between cities will help to optimize the allocation of spatial resources and urban-rural spatial layout in the province, and to promote the healthy development of urban transformation and urbanization in the province. In this paper, the gravity model is introduced to calculate the spatial gravity value of 11 cities in Shanxi Province, and the level and spatial pattern of spatial interaction between cities in Shanxi Province are studied according to the results calculated by the fracture point formula. The results show that Taiyuan has a significant core position and a prominent feature of high primacy. The central Shanxi urban agglomeration forms a highly related region, with Taiyuan, the provincial capital, as the core. The urban development of Shanxi Province is eccentric. Finally, from the starting point of improving the comprehensive strength of the city, and optimizing the traffic network and regional connection level, the paper puts forward countermeasures and suggestions to strengthen the level of interaction between cities in Shanxi Province, in order to improve the level and quality of urbanization in Shanxi Province, to optimize the spatial layout of urbanization in Shanxi Province, and to enhance the vitality and competitiveness of the cities at all levels.
