山东省城市经济影响区的格局变化

Evolution of urban economic effect regions in Shandong Province

基于城市地理学相关理论,运用M ann-Kendall方法对改革开发以来山东省经济发展阶段进行了划分,寻找出城市经济发展的突变年份,并通过计算综合得分确定了各发展阶段中心城市等级;依据势能模型,采用ArcG IS的栅格法判明各栅格归属的中心城市,并确定了不同发展阶段各等级中心城市经济影响区的地域格局及其变化趋势。结果表明:全省经济重心向东部沿海地区转移,半岛城市等级提升与影响增强,城市经济影响区差异显著,进而从城市经济发展水平、交通通达率、人文社会及自然与区位条件等方面探讨了影响山东省城市经济影响区变化的机制。

This paper conducts the principles of economic geography science and urban geography science. Firstly, Shandong Province economic development has been divided into different stages through the method of Mann-Kendall. Then, the sudden-change years of urban economic development are obtained, and the key city rank is determined through synthesis scores. And then potential model is established, the ownership key cities of various grids are obtained using the grid law of Arc-GIS, The results show that the economic center of gravity migrates to the east coast area, the level of the influence area of peninsula city promotes gradually and its influence strengthens and the difference of various urban areas is enlarged. Finally, the main effect factors of urban economic area changing in Shan-dong Province are discussed including the level of urban economic development, traffic understanding rate, social culture and the conditions of nature and location.
