摘　　要：本文以宜春学院常见的香樟(Cc)、红花檵木(Lc)、红叶石楠(Ps)、金边黄杨(Ej)、杜英(Es)、木樨(Of)、广玉兰(Mg)、海桐(Pt)、小叶女贞(Lq)、山茶(Cj)为研究对象,对这10种常绿植物叶片进行单位叶面积滞尘量的测定,并进行综合指标评价。结果表明,园林植物滞尘能力的指标可分为3个层次,其中红叶石楠滞尘能力最强,香樟和杜英滞尘能力最弱,在粉尘同一来源的情况下,不同园林树种的滞尘能力有显著差异;10种园林植物综合滞尘能力按从大到小排列顺序为:Ps、Lc、Lq、Mg、Pt、Ej、Of、Cj、Es、Cc;通过叶面微结构观察,叶面气孔开度、叶面绒毛及叶面粗糙度等叶面特征是影响滞尘效果的重要因素。In this paper,10 common evergreen species on Campus of Yichun University were the study objects including Cinnamomum camphora(Cc),Loropetalum chinense var.rubrum(Lc),Photinia×fraseri(Ps),Euonymus japonicus'Aurea-marginatus'(Ej),Elaeocarpus decipiens(Es),Osmanthus fragrans(Of),Magnolia grandiflora(Mg),Pittosporum tobira(Pt),Ligustrum quihoui(Lq)and Camellia japonica(Cj)to measure the dust-retention volume per unit leaf area and carry out comprehensive index evaluation.The results showed that the dust-retention capacity indexes of the landscaping plants could be divided into 3 levels in which Photinia×fraseri had the highest dust-retention capacity while C.camphora and E.sylvestris had the lowest capacity.The dust-retention capacities of different landscaping species were significantly different for the same sourced dust.The ranking for the comprehensive dust-retention capacity of the 10 landscaping species was:Ps>Lc>Lq>Mg>Pt>Ej>Of>CJ>Es>Cc.Observation of the leaf microstructure showed that the leaf surface features including stomatal aperture,surface pubescence and roughness were key dustretention factors.
