西安市邮政公共服务设施空间布局分析

Spatial layout analysis of Xi an postal public service facilities

为解决邮政公共服务设施发展不均衡、布局不合理问题,剖析邮政公共服务设施空间布局特征,以西安市为研究对象,综合运用Voronoi图法、核密度分析法以及方向分布分析法,探究基于ArcGIS的邮政公共服务设施空间分布测度、密度和趋势。结果表明,空间分布测度呈现“整体随机、局部凝聚、少数均匀型”布局模式,空间分布密度整体相对均衡,局部范围凝聚,空间分布趋势呈现由东北-西南方向延伸。邮政公共服务设施规划应以布局特征为依据,针对性地调整优化,统筹协调各区域间的设施分布。

In order to solve the problems of unbalanced development and unreasonable layout of postal public service facilities,the spatial layout characteristics of postal public service facilities are analyzed.Taking Xi an as the research object,the Voronoi diagram,kernel density estimation and standard deviational ellipse are comprehensively adopted to explore the spatial distribution measurement,the density and trend of postal public service facilities based on ArcGIS.The results show that:the spatial distribution presents‘overall random,local agglomeration,and a few uniform’distribution;The spatial distribution density is relatively balanced as a whole,and the local range is condensed;The spatial distribution trend extends from northeast to southwest.The planning of postal public service facilities should be based on the layout characteristics,targeted adjustment and optimization,and coordinate the distribution of facilities among different regions.
