| 摘 要： | 在GIS动态分段基本原理的基础上,将铁路车站的里程作为路径系统测量M值的校准参考依据,部分铁路货运量(用装车数表征货运量的大小)作为线事件引入到铁路网的货流径路系统中,实现了铁路货运量的可视化表达,并根据发站和到站自动沿线绘制货运方向箭头,为铁路货运运输分析和研究决策提供技术支持.

| Abstract: | Based on the analysis of the basic principles of GIS dynamic segmentation,it was put the mileage of railway station as calibration reference values of M for path measurement system.Part of the railway freight volume （characterized by the number of loading cargo） was used as the event into the railway path system to implement a visual representation of railway freight volume.According to start station and end station automatically,the direction arrow of freight transport along the railway line was drawn.The paper provided a scientific support to make decision for the railway transportation analysis and research. |
