摘　　要：本研究通过对合肥市瑶海区磨店乡道路绿化灌木的实际调查,在道路环境大致相同的情况下,选择5种常见的常绿灌木:红叶石楠、海桐、红花檵木、法国冬青、金边黄杨,比较分析各灌木在道路绿化中叶片滞尘的能力。结果表明,滞尘能力最强的是法国冬青,单位叶面积滞尘量为2.1366 g/m^2,滞尘能力较强的有红叶石楠和红花檵木,单位叶面积平均滞尘量分别为1.6791 g/m^2,和1.8612 g/m^2,海桐的单位叶面积平均滞尘量为0.8365 g/m^2,金边黄杨的滞尘能力最低,单位叶面积滞尘量平均为0.6583 g/m^2。法国冬青的滞尘能力受环境影响最大,其次是红叶石楠和海桐。The greening shrubs were investigated in Yaohai District,Hefei city.Five common evergreen shrubs were choosen in the roughly the same road environment:Photinia×fraseri Dress,Pittosporum tobira,Loropetalum chinense var.rubrum,Viburnum odoratissimum Ker-Gawl.,Euonymus japonicus Thunb.var.aureo-marginatus Hort.The dust retention capacity of leaves was analyzed and compared.The results showed that the strongest dust-retaining capacity is Viburnum odoratissimum Ker-Gawl,the average dust retention per unit area is 2.1366 g/m^2.Photinia×fraseri Dress and Loropetalum chinense var.rubrum were followed,the average dust retention is 1.6791 g/m^2 and 1.8612 g/m^2,the average dust retention per unit area of Pittosporum tobira is 0.8365 g/m^2.Euonymus japonicus Thunb.var.aureo-marginatus Horts average dust retention was the lowest,0.6583 g/m^2.The average dust retention capacity of Viburnum odoratissimum Ker-Gawl was affected by the environment the most,followed by Photinia×fraseri Dress and Pittosporum tobira.
