| 摘 要： | 运用分形理论,对县域层面上的无棣县城镇体系的随机聚集度进行了研究.通过聚集维数的计算,得出了无棣县城镇体系的随机聚集特征.结果表明,无棣县城镇体系聚集特征明显,以无棣镇为中心,呈扇形分布,而无棣镇并不位于县域中心,只是位于西南一隅;县域内各乡镇按照距离县城的远近,分为3个不同的层.在此基础上,提出了大力发展中心城镇无棣镇的同时积极培育次级中心城镇柳堡镇,形成无棣—柳堡发展轴线;重点加强周边城镇之间的道路交通、通讯等基础设施建设;发展特色产业,打造黄河三角洲县域海洋开发基地等建议.

| Abstract: | This paper uses fractal theory and mathematical model,from the view of county territory level,to research the random aggregation of urban system in Wudi County.By calculating aggregation dimension,the characteristics of urban system of Wudi County are shown as follow:the aggregation characteristics are apparent,taking Wudi Town as the center,showing fan-shaped distribution,however,Wudi Town is not at the center of the county,but at the southwest corner;in accordance with the different distance from the mark... |
