基于空间分析的铁路危货办理站吸引区域研究

摘要

The division of the attractive region of railway dangerous goods stations is very important to macroscopic planning of railway dangerous goods stations. Combined with the GIS and spatial structure analysis, the paper uses node buffer analysis, cellular automaton model, and the shortest path by using ArcGIS spatial analysis module to study the attractive region of eight railway dangerous goods stations in Sichuan province of China respectively. Meanwhile the paper compares three different methods and offers suggestions on railway dangerous goods stations layout optimization in Sichuan province.%铁路危险货物办理站吸引区域划分是铁路危险货物办理站宏观布局规划的重要依据.结合GIS和空间结构分析,分别利用节点缓冲分析、基于元胞自动机的铁路危货办理站吸引区模型和基于ArcGIS空间分析模块的最短路径方法对四川省境内八个办理站点吸引区域进行了研究,总结比较了三种方法,并对四川省当前铁路危货办理站布局优化提出了建议.
