基于局域空间自相关的城市ATM空间布局分析——以武汉市武昌区为例

Analysis of Spatial Distribution of ATM Machine in Urban Area Based on the Local Spatial Autocorrelation——A Case Study of Wuchang District in Wuhan City

以武汉市武昌区为例,运用加权Voronoi图,定性、定量地分析了武昌区ATM整体空间和各街区的空间布局结构及集聚分布。对ATM与人口密度、道路可达性、商业设施、金融设施以及公共服务设施密度等多个要素之间进行局域空间自相关分析,研究各因子对ATM空间布局的影响程度,为进一步解决ATM布局的问题提供有效的思路和手段。结果表明:人口密度、道路密度、金融密度等因子在全局及局部上影响着ATM的空间布局,而人口密度的影响最明显;ATM的集聚核区域及均匀分布区域落在空间正相关的热点区域,表现为高密度城市化发展水平越高,各影响因子对ATM的密度与集聚程度影响越显著。

Taking Wuchang District in Wuhan City as a case,using weighted Voronoi diagram,the spatial distribution of ATM was qualitatively and quantitatively analyzed.Then local spatial autocorrelation analysis was conducted on ATM and population density,road accessibility,commercial facilities,financial facilities and public service facilities density.The impact of each factor on the spatial distribution of ATM was studied,which can provide an effective means for the further ideas of solving ATM layout problems.The results showed that population density,commercial facilities density and road density affect the spatial distribution of ATM obviously with two variable regional spatial autocorrelation analysis,which population density perform more significantly.Higher the development level of the high density city,more obvious the effect of various factors on density and the degree of agglomeration of ATM.
