摘要
受恶劣的自然条件和落后的社会经济状况制约,山区县的城镇建设存在很多制约因素,其独特的城镇体系结构具有重要的研究意义。运用分形理论,以贵州乌蒙山区为例,对其规模结构、空间分布进行研究,结果表明该区域城镇体系具有分形特征。其等级规模分布具有典型的"双核心"结构特征,城镇体系呈明显的沿线分布,主要城镇均分布在几条地理要素上,各城镇之间联系不紧密。在上述分析的基础上,对城镇体系结构优化提出几点建议。
Due to poor natural conditions and socio-economic backwardness,city construction of the mountainous area exists many restriction factors.Its unique urban structure has important research significance.Taking Guizhou＇s Wumeng Mountainous Area as an example,the size distribution and space distribution of cities has been studied with the fractal method.The conclusion shows that the distributions take on fractal structure.The size-scale structure has characteristics of typical ＂dual-core＂ structure;the space distribution is linear,and most small towns lie on a geographic area;the capacity of spatial interaction is weak.Finally some advice is put forward for advancing structure of the urban system based on the study results.
