基于POI数据的株洲市物流业空间格局研究

Research on Spatial Pattern of Logistics Industry in Zhuzhou Based on POI Data

以株洲市POI兴趣点为研究对象,借助ArcGIS软件从三个方面对株洲市物流业空间格局进行研究:首先,通过核密度分析和平均最邻近分析方法,对株洲市物流业聚集水平进行研究;第二,利用标准差椭圆分析方法,对株洲市物流活动整体空间分布特征进行研究;第三,采用缓冲区分析方法,对株洲市各类物流业POI兴趣点的区位行为进行研究。研究结果表明,株洲市物流活动在中心广场附近区域聚集效应明显。

Taking Zhuzhou's POI interest point as the research object,this paper studies the spatial pattern of Zhuzhou's logistics industry from three aspects by using ArcGIS software:Firstly,the agglomeration level of Zhuzhou's logistics industry is studied by kernel density analysis and average nearest neighbor analysis;second,using standard deviation ellipse analysis method to study the overall spatial distribution characteristics of Zhuzhou logistics activities;thirdly,the buffer analysis method is used to study the location behavior of POI interest points of various logistics industries in Zhuzhou.The results show that the agglomeration effect of logistics activities in Zhuzhou is obvious near the central square.
