摘　　要：以黑龙江省野生护坡草本植物的筛选为目标,应用层次分析法(AHP法)对选定的16个指标属性进行了分析,得出的重要指标按权重大小依次是:根系密度、生长速度、耐瘠薄性、抗旱性、根长、地上生物量、株型、使用年限。通过大规模野外调查和室内试验分析,对黑龙江省境内7条主要高等级公路边坡常见的21种草本植物进行了综合评价:草地早熟禾(Poa pratensis)、冰草(Agropyron cristatum)、野苜蓿(Medicago falcata)、无芒雀麦(Bro-mus inermis)、旱麦瓶草(Silene jenisseensis)、月见草(Oenothera biennis)、马蔺(Iris lacteavar.chinensis)、紫花地丁(Vi-ola alisoviana)、偃麦草(Elytrigia repens)、飞蓬(Erigeron acer)、蒲公英(Taraxacum mongolicum)、平车前(Plantagodepressa)12种植物各项指标表现优秀,可作为黑龙江省及气候类型相同的寒区主要的公路护坡先锋草本植物。Sixteen appraisal indexes were selected by the analytic hierarchy process aiming at getting the suitable plants for highway side slopes. Some important indexes, including root density, growth rate, barren resistance, drought-resistance, root length, aboveground biomass, plant-type, age of utilization, were used to evaluate 21 herbaceous plants grown on the side slopes of seven highways in Heilongjiang Province. Result shows that Poa pratensis, Agropyron cristatum, Medicago falcate, Bromus inermis, Silene jenisseensis, Oenothera biennis, Iris lactea var. chinensis, Viola alisoviana, Elytrigia repens, Erigeron acer, Taraxacum mongolicum and Plantago depressa are excellent species, which can be used as the suitable pioneer plants for highway side slopes in cold regions.
