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。
Based on the demographic data and toad network structure of each town in Panzhihua City,a comprehensive study is carried out regarding the features of population distribution and spatial layout of roads and the spatial correlation between them through the utilization of spatial analysis technology.The study indicates that：both population distribution and road layout possess spatial correlation,with positive correlation for both,which means that the population distribution and road layout of this city are not completely random,instead are following the spatial clustering between the spatial similarity values.In order to further discuss the spatial correlation between population distribution and road layout,analysis on them is carried out through spatial bivariate correlation,and the result indicates that thrre is a relatively strong positive corrrelation between population distribution and road layout.Meanwhile,the local spatial coorelation dendrogram indicates that there are ＂high-high＂ and ＂low-low＂ clusters of population distribution and road layout,which means that the degree of population density is fairly influenced by the road density,and further proves their correlation with the mutual influence on each other.The conclusion of this study provides the new study approaches and theoretical support for the urban planning of Panzhihua.
