摘要
以西北干旱区城市酒泉市为例,运用定性和定量两种方法对市域城镇体系空间结构进行分析研究。介绍了分形理论及其在城镇体系研究中的应用,对城镇空间结构进行定性分析;其次,运用分形理论中的网格维数和关联维数模型对城镇空间结构进行定量分析,结果表明该区域城镇体系空间结构具有分形特征,与定性分析结果一致;最后,在上述分析的基础上提出城镇空间结构优化建议。
Taking the Jiuquan city in the arid region of northwest China as an example,this essay analyzes and studies the spatial structure of urban system by means of qualitative and quantitative analysis.In the first place,it introduces the fractal theory and its application to research on the urban system and analyzes qualitatively the urban spatial structure;secondly,it exercises the grid dimension and correlation dimension model to analyze the urban spatial structure quantitatively,proving that the urban spatial structure in this region has fractal characteristics,which are in line with the qualitative analysis;finally,it puts forward some optimization suggestion on the urban spatial structure based on the above-mentioned analysis.
