摘 要: 以无棣县为例,运用分形理论,在对该县城镇体系基本概况研究和认识的基础上,采用数学模型,运用城镇体系的3种分形维数:聚集维数、关联维数和网格维数,对无棣县城镇体系的空间结构进行深入研究。得出结论:无棣县城镇体系随即聚集特征较明显;城镇体系空间关联程度一般,城镇之间的通达性与理想状态差距较大;城镇体系总体空间分布均衡性适中。基于此,为该县城镇体系的优化提出了合理性建议。
关 键 词: 城市地理;分形理论;空间地域结构;分形维数;县域城镇体系;无棣县

Abstract: This paper takes Wudi county for example, using the fractal theory, under the premise that researching and understanding the general situation of urban system in Wudi county, using the three fractal dimensions which are Aggregation dimension, Correlation dimension and Gridding dimension, to deeply research the spatial structure of Wudi county. The results show that the feature of aggregation is relatively obvious, the degree of spatial association is ordinary, comparing to ideal state, the accessibility of the towns has larger gap and the balance of spatial distribution is moderate. On this basis, rational suggestions for optimization of spatial structure of this county’ urban system are proposed.
Key words: urban geography; fractal theory; spatial structure; fractal dimension; urban system of county; Wudi county
