摘　　要：为了提高高速公路中央分隔带防眩植物类别筛选效率,提出了防眩植物选择方法。首先总结了防眩植物选择原则、配置模式和要点,通过定性和定量相结合的方式,从植物立地条件、功能特性和培育特性等3个方面构建了防眩植物选择体系,并利用层次分析法(AHP)对各指标进行权重计算;进一步建立了“先筛选后排序”和分类评价的防眩植物选择方法,通过乡土植物调查充实植物选择库,并建立各指标的综合评价等级标准,将防眩类植物和搭配类植物分别进行量化评价,依据评价得分顺序选出推荐的植物类别。研究结果表明:各指标重要度排序为中央分隔带条件>防眩功能>乡土适应性>生长特性>地理区位>景观功能>培育成本;对泰东高速公路进行案例分析,得出其中央分隔带植物搭配推荐模式为:圆柏/白杄+沙棘/榆叶梅/金叶女贞+野牛草/结缕草。In order to improve the screening efficiency of antiglare plants species on median strip of expressway,a selection method of antiglare plants is proposed.Firstly,the selection principle,arrangement mode and key points of antiglare plants are summarized.From a combination of qualitative and quantitative methods,the selection system of antiglare plants is constructed from three aspects:site conditions,functional characteristics and growth characteristics,and the weight of each index is calculated by AHP.Furthermore,a method of "screening before sorting" and classification evaluation for antiglare plants selection is established.The plant database is enriched through the investigation of native plants,and the comprehensive evaluation standards of indexes are established.The antiglare plant and the subsidiary plant are evaluated respectively,and the recommended plant species are selected according to the evaluation score sequence.The results show that the importance of indexes is in the order of central partition conditions>antiglare function>local adaptability>growth characteristics>geographical location>landscape function>cultivation cost.Analysis is carried out relying on the Tai’an-Dongping Expressway,and the recommended pattern of plants on median strip is as follows:Sabina chinensis/picea meyeri rehd+hippophae rhamnoides linn/amygdalus triloba/ligustrum vicaryi+buchloe dactyloides/zoysia japonica steud.
