摘　　要：筛选适宜高速公路生态声屏障种植的植物种类和基质配方,为高速公路生态声屏障的构建提供参考。首先,通过盆栽试验筛选出适宜南昌高速公路环境生长的植物种类;然后,基于不同配方基质对筛选出的植物进行声屏障种植试验,观测植物的存活率、生长势、覆盖效果、景观效果等指标,评估不同配方基质对供试植物生长的影响;最后,测定基质的理化性质,利用隶属函数法筛选出适合用于生态声屏障的种植基质配方。结果表明:盆栽实验中,藤本月季、爬山虎、垂盆草、花叶络石、扶芳藤5种植物的存活率为100%,铁芒萁、薜荔、乌蕨、地菍、地果均存在一定比例死亡率,乌蕨全部死亡;声屏障种植实验中,爬山虎、花叶络石、扶芳藤在5种基质中存活率为100%,藤本月季存在约20%的死亡率,垂盆草仅在T1(泥炭∶腐熟枝条∶蛭石∶青石∶园土=4∶0∶3∶2∶27)、T3(泥炭∶腐熟枝条∶蛭石∶青石∶园土=4∶4∶0∶1∶27)中有10%的存活率,所有供试植物在T3中的生长势、覆盖效果、景观效果总体呈现最佳,T3的隶属函数综合评价指数最大。花叶络石、藤本月季、扶芳藤、爬山虎更适宜作为南昌高速公路生态声屏障种植材料,T3(泥炭∶腐熟枝条∶青石∶园土=4∶4∶1∶27)为最佳种植基质。This paper screens suitable plant species and substrate formulas for planting ecological sound barriers on highways,which provides a reference for the construction of ecological sound barriers on highways.Firstly,plants suitable for the growth of the expressway environment were preliminarily screened through pot experiments.Then,sound barrier planting experiments were conducted on the selected plants based on different formula matrices.The effects of different matrix formulations on the growth of the tested plants are evaluated by observing the survival rate,growth trend,coverage effect,landscape effect of plants.Finally,based on the determination of the physicochemical properties of the substrates,the membership function method is used to screen suitable planting substrate formulas for ecological sound barriers.The results show that in the potted experiment,the survival rate of five species,including Climbing Roses,Parthenocissus tricuspidata,Sedum sarmentosum,Trachelospermum jasminoides'Flame'and Euonymus fortune,was 100%.Dicranopteris linearis,Ficus pumila,Melastoma dodecandrum,and Ficus tikoua all have a certain proportion of mortality rate in potted experiments with all Stenoloma chusanum dying.In the barrier planting experiment,the survival rate of Parthenocissus tricuspidata,Trachelospermum jasminoides'Flame'and Euonymus fortune was 100%in five substrates.The mortality rate of Climbing Roses was approximately 20%.The survival rate of Sedum sarmentosum was 10%in the T1(peat:decomposed branches:vermiculite:bluestone:garden soil=4:0:3:2:27)and T3(peat:decomposed branches:vermiculite:bluestone:garden soil=4:4:0:1:27).And it died in all other experimental groups.All the tested plants showed the best overall growth potential,coverage effect and landscape effect in the T3 experimental group.So,the comprehensive evaluation index of the membership function of the substrate in the T3 experimental group was the highest.
