区际联系是区域地理学重要的研究内容之一.通过城市间经济联系的测算可以明确城市的主要联系方向.这将有利于城市和区域经济的空间组织、城市实体的空间发展方向确定、交通运输的合理组织.文章引入区域间相互作用的引力模型,以福建省作为研究对象,测算出城市间的经济联系强度,并用对应的航空、公路和铁路客运联系资料进行验证,得出福建省内部的主要联系方向以及省际的主要联系方向,为福建省内部的空间整合和外部的空间扩展提供重要的决策参考.
Interregional contact constitutes one of the important research objects of regional geography research on the main direction by calculating intercity economic contact is vital to interregional spatial forming, to understanding urban sprawl and rational transportation. By use of gravity model, this article calculates the economic contact intensity among cities in Fujian Province and the other core metropolises all over the country, validates them with the referential data of aviation, highway and railway passenger traffics. Then,it puts forward the internal and external main direction of Fujian Province.
