摘　　要：铁路交通是一条带状建筑物,它对沿线自然环境的影响很复杂,根据这个特点,在对铁路环境影响进行评价时,采用"目标—指标层次结构"模式,利用层次分析法(AHP),把定性和定量的指标结合起来,先筛选出部分重要的单项指标并确定其权重,然后利用消去与选择转换法(ELECTREⅡ),建立优先度、低劣度、理想度和劣指标比例度4个矩阵,最后根据所确定的门槛值和所绘制的优先图,对方案进行比选和排序,直到选择出最优方案.在文末给出实例进行验证.The railway traffic is a strip construction which has a complicated impact on the entironment along the railway line.Based on this,the "object-index hierarchy structure" mode was adopted and AHP was made use of in order to integrate the qualitative indexes with the quantitative indexes in the process of railway environment influence assessment.Firstly,part of important indexes were chosen and their weights were confirmed.Then ELECTREⅡ was used to establish priority matrix、low intensity matrix、ideal degree m...
