| 摘 要： | 为了确定最优线路方案，综合地形、地物和环境影响等8个因素，包括:坡度、坡向、土地利用、道路、建筑用地、水域和湿地、植物群落和文物古迹等，作为区间铁路线路方案评价指标，建立了基于地理信息系统（GIS）的层次分析法（AHP）线路方案比选模型。以辽宁省康平站—法库站区间铁路线路方案比选为例，进行了基于 GIS 的 AHP 线路方案比选评价分析。该线路方案比选模型对于铁路线路生态环境保护、降低工程造价、避免工程灾害具有重要作用。

| Abstract: | In order to determine the optimal line scheme, terrain, features and environment (slope, slope direction, land use, road, construction land, waters and wetlands, plant communities and cultural relics) were used as the evaluation indexes of railway lines. Based on GIS, an evaluation model of AHP route schemes was established. Taking the railway line scheme between Kangping Station and Faku Station in Liaoning Province as an example, the comparison, selection and analysis of AHP line based on GIS were carried out. The comparison model plays an important role in protecting the ecological environment of railway lines, reducing the project cost and avoiding engineering disasters. |
