【摘要】：以攀枝花市各乡镇人口数据和道路路网结构为基础,运用空间分析技术综合研究人口分布和道路空间布局特征以及两者之间的空间关联性。研究表明:人口分布和道路布局均具有空间关联性,且均为正相关,说明该市人口分布和道路布局并非完全随机性,而是遵循空间相似值之间的空间聚集。为进一步探讨人口分布与道路布局之间的空间关联关系,采用双变量空间自相关对两者进行分析,结果表明人口分布与道路布局亦存在较强的正相关关联性。同时,局部空间自相关聚类图显示存在人口分布和道路布局"高-高"聚集和"低-低"聚集片区,说明人口聚集程度受道路密度影响较大,进一步证实了两者间相互影响的关联关系。研究结论为攀枝花市城市规划提供了新的研究思路和理论支持。
[Abstract]:Based on the population data and road network structure of every township in Panzhihua City, the spatial analysis technology is used to study the characteristics of population distribution and road spatial distribution and the spatial correlation between them. The results show that both population distribution and road layout have spatial correlation, and both are positive correlation, which indicates that the population distribution and road layout in this city are not completely random, but follow the spatial aggregation of spatial similarity values. In order to further explore the spatial correlation between population distribution and road layout, bivariate spatial autocorrelation is used to analyze the two. The results show that there is also a strong positive correlation between population distribution and road layout. At the same time, the local spatial autocorrelation clustering diagram shows that there are "high-high" and "low-low" aggregation areas in population distribution and road layout, indicating that the degree of population aggregation is greatly influenced by road density. Furthermore, it is proved that the relationship between them is related to each other. The conclusion provides new research ideas and theoretical support for the urban planning of Panzhihua City.
