| 摘 要： | 应用改进的层次分析法(AHP)对贵州省铁路路网进行适宜性评价。首先,考虑地方吸引范围、人口密度、地形地貌、沿途岩性条件及地质灾害分布等指标,建立路网适宜性评价指标体系;然后,引入梯形模糊数,综合考虑指标的主观权重,用层次分析法(AHP)对贵州省既有路网进行适宜性评价;最后,在GIS环境下编制贵州省铁路路网适宜程度区划图。

| Abstract: | The purpose of this study was to evaluate the suitability of Guizhou railway network based on improved Analytic Hierarchy Process(AHP).First,local range of railway covering,population density,topography,lithology and distribution of geological hazards were taken as independent factors to form assessment indicator system.Then,the weights of these factors were calculated based on the approach of trapezoidal fuzzy number weighting.Furthermore,Guizhou railway network suitability was evaluated by using Analytic ... |
