鲁南经济带空间结构的分形研究

Fractal Study on Spatial Structure in Lunan Economic Belt

为了定量分析鲁南经济带空间结构的分形特征,文章分别计算了其城镇体系空间分布的关联维数与聚集维数.结果显示,鲁南经济带城镇的空间布局较为分散,城镇空间关联程度一般;城镇空间向心性集聚分布特征比较显著.为此,提出加强交通基础设施建设,重点打造"一圈一区",增强区域"双核动力",构建"济临日"三角结构等促进措施.

In order to quantitatively analyze the fratal features of spatial structure in Lunan Economic Belt,the article calculates the correlation dimension and agglomeration dimension of spatial distibution of urban system.The results show the spatial lagout of the aties and towns in lunan Economic Bell is more dispersed,and the correlation degree between the cities and towns is general,the centripetal distribution of urban space is more obvious.There fore,the author proposes to strengthen the construction of transport infrastructures,to build＂a Metropolitan and a District＂,to enhance the ＂dual-core power＂ and establish the ＂J-L-R＂ triangular structure.
