物流中心地规模与空间结构分形研究:丝绸之路经济带西北五省区数据分析

Fractal Research on Scale and Spatial Structure of Logistics Central Place: Data Analysis of Five Northwest Provinces & Regions along Silk Road Economic Belt

运用分形理论,选取西北五省区物流中心地体系作为研究对象,对其规模与空间结构进行分析,研究结果表明:第一,西北五省区物流中心地体系中一级物流中心地首位度较为理想,首位物流中心地乌鲁木齐市的垄断性不强,各中心地分布相对均衡有序,物流中心地位序规模结构良好;第二,物流中心地空间作用较强,在关联性和空间分布方面都具有较好的均衡性;第三,分别以乌鲁木齐市、西安市、兰州市为核极,呈现向其他15个物流中心地密度衰减的态势,说明物流中心地体系为高紧致度的结构体。

In this paper, using the fractal theory, we analyzed the scale and spatial structure of the logistics central place system of the five Chinese northwestern provinces and regions. The results show that: first, the tier-one points in the logistics central place system of the five had ideal primacy ratio, while Urumqi as the primary logistics center is not a strongly dominant one, and the distribution of other centers was relatively balanced and in good order, contributing to the good order and sound structure of the central place system;second, the logistics central place has a strong spatial role to play and is well balanced in terms of correlation and spatial distribution;third, with Urumqi, Xi’an and Lanzhou as the nuclei, the system shows the trend of density decline toward the other 15 logistics central places, indicating that the logistics central place system is a highly compact structure.
