基于POI数据的城市易燃易爆场所空间布局研究——以郑州市四环内为例

Research on spatial layout of urban flammable and explosive places based on POI data:taking four rings in Zhengzhou city as an example

文章基于百度地图爬取的易燃易爆场所POI数据,运用ArcGIS空间统计工具,分析郑州市四环以内易燃易爆场所的空间布局特征,研究发现:(1)郑州市四环以内易燃易爆场所呈现出显著的空间集聚分布特征,集聚区域主要分布在管城区、金水区和二七区。(2)易燃易爆场所存在3种空间布局模式,分别是以加油站为代表的外向分布型,以化工厂、加气站和仓库仓储为代表的内向聚合型以及工业园区为代表的稳定聚合型。

Based on the POI data of flammable and explosive places crawled by Baidu map,this paper uses ArcGIS spatial statistical tools to analyze the spatial layout characteristics of inflammable and explosive places within the fourth ring of Zhengzhou.The research shows that the inflammable and explosive places within the fourth ring of Zhengzhou has significant spatial agglomeration distribution characteristics,and the agglomeration areas are mainly distributed in Guancheng District,Jinshui District and Erqi District.There are three kinds of inflammable and explosive places.The spatial layout mode is an outward-distribution type represented by a gas station,an inward polymerization type represented by chemical plant,LPG stations,and warehouse,and stable polymerization type represented by an industrial park.
