环渤海港口城市体系发展与布局探讨

选取环渤海地区14座港口城市,从城市规模分布、城市经济发展外向性水平和城市空间结构3方面探讨环渤海港口城市体系的发展与布局。选用1993—2003年年末城市总人口数据,应用位序—规模法则探讨环渤海港口城市的规模分布;采用外贸出口额、外商直接投资额、出口依存度3个指标分析城市经济发展的外向性水平;测算城市体系中各城市间的直线距离,应用分形理论分析环渤海港口城市空间结构。结果显示:1)环渤海港口城市规模分布属于相对均衡型,接近位序—规模分布形式;2)在城市体系中,城市经济发展的外向性水平具有层次性,青岛、天津、大连3市相对突出;3)城市体系空间布局比较均衡。

Discussion on the Development and the Layout of the Cities in the Bohai Rim

This article's aim is to discuss the development and the layout of the 14 cities in the Bohai rim.This article chooses total population of each city from 1993 to 2003.It contains three facets,that is,discussing the cities'layout of scale by using Rand-Size Rule,discussing the export-orientated level of the economic development by using the volume of trade for external trade,the foreign direct investment and the dependence on external trade,and discussing the spatial structure by using the Fractal Theory.In the end,this article presents the consequence: First,the cities' layout of scale nears the Rand-Size layout,and its changes also present as Rand-Size layout.Second,the export-orientated level of the economic development has hierarchy.That is,Qingdao,Tianjin and Dalian are relatively prominent.Third,the spatial layout is inclined to equilibrium.
