摘　　要： 以交通部"西部高速公路生态型声屏障技术应用研究"课题为依托,开展高速公路生态型声屏障评价指标体系研究。基于AHP层次分析法,提出了由功能性、环保性、景观性以及经济性4个准则层指标和23个具体评价指标构成的一套高速公路生态型声屏障评价指标体系。工程应用结果表明,该体系能客观地反映高速公路生态型声屏障特征,评价结果更趋合理,可作为高速公路生态型声屏障建设方案选取的重要依据。 To conduct the research subject of ＂Application of Ecological Sound Barrier Technology for Western Expressways＂ sponsored by the Ministry of Transport,the evaluation index system of ecological sound barrier was studied.Based on analytic hierarchy process（AHP）,the evaluation index system consisted of 23 indexes from four principal respects,i.e.,function,environmental protection,landscape and economy.Engineering application results showed that the index system objectively reflected the characteristics of ecological sound barrier of expressway and the evaluation conclusion was more reasonable as important basis for the construction of expressway sound barrier.
