基于GIS物流交通网络可达性研究--以宁波建立全球物流分销中心为例

摘要

在宁波建立全球物流分销中心背景下，文章利用ArcGIS的分析功能研究物流交通网络的可达性。首先建立了可达性评价指标体系，并依据此选出较为重要的物流节点；其次利用ArcGIS的分析功能，对三个候选地址的可达性进行计算。由于主要物流园区的权重无法确定，文中设定其权重范围（0，10]，直接利用mathematics获取可达性变化趋势，最终获得较为科学的结论。%In the background of building global logistics distribution center in Ningbo , this paper analyzed the accessibility of logistics transportation network in ArcGIS. First , it set up the accessibility evaluation system to select important logistics nodes; then, this paper evaluated the accessibility of the three candidate addresses in ArcGIS. For the weight of the main logistics area can not be determined , this paper set the range of weight in (0,10], used mathematics to obtain the trends directly, thus reachds a more reasonable conclusion.
