基于引力模型的福建城市空间格局及经济影响范围变化研究

Spatial Patterns of Cities and the Change of Economic Influencing Regions in Fujian Province Based on Gravity Model

根据引力模型的原理,结合断裂点理论,通过对福建省9个城市间引力值和断裂点距离的计算和分析,研究福建省2000—2013年间城市空间格局及其经济影响范围的变化。结果表明:福建省以福州和厦门为双核心的城市格局发展稳定,并已初步形成沿海两大都市圈,西北内陆山区以独立中心城市发展为主,沿海与内陆发展差异显著,13年间城市经济影响范围变化不大。提出应稳定双核心城市发展格局,以沿海带动内陆,注重内陆基础设施建设,扩大内陆城市的经济影响范围,达到内陆与沿海城市的协调发展。

Based on the gravity theory and break-point formula, and through the calculation and analy- sis of the nine cities＇ gravity value and break-point distance in Fujian province, the change of urban spatial patterns and their economic influencing regions were studied from 2000 to 2013. The result showed that with the development of Fuzhou and Xiamen, traditionally as dual core cities, of two coast- al metropolis circles had been initially formed, and northwest inland took a center city-based independ- ent development mode. There were significant differences in the development of coastal area and in- land; while during the 13 years urban economic influence area changed little. Suggestions are made to stabilize the development patterns of the dual core cities, in order to coordinate the development of coastal area and inland, to focus on the inland infrastructure construction and to expand the economic influence regions of the inland.
