摘要：比较了南京市20种主要绿化树木的不同时间和不同功能区的滞尘能力，并通过叶片性状、叶表微形态结构和叶面距地高度等因素分析了综合滞尘能力的差异．结果表明，同种绿化树木滞尘能力的季节变化规律为秋季〉春季〉夏季，绝大多数绿化树木的不同功能区滞尘能力差异显著（P〈0．05），不同类型的树木滞尘能力表现为阔叶灌木〉常绿阔叶乔木〉落叶阔叶乔木．根据综合滞尘能力的大小，将20种绿化树木划归为3类：金叶女贞、广玉兰、八角金盘、海桐、小叶黄杨和构树等滞尘能力〉0．4mg·cm^-2，划归为第一类；女贞、悬铃木、香樟、紫叶李、珊瑚树、紫薇、大叶黄杨和银杏等滞尘能力在0．2～0．4mg·cm^-2，划归为第二类；樱花、枫杨、杨树、桃树、刺槐和鸡爪槭等滞尘能力〈0．2mg·cm^-2，划归为第三类．
The dust retention capacities of 20 afforest tree species in different compared. The comprehensive dust retention capacities affected by time and areas in Nanjing are facts of blade character, micromorphology properties and the height of a leaf surface are made a analysis. The results indicated the same tree species showed different dust detaining abilities in different season, Autumn ）Spring Summer. The difference of dust retention capacities of overwhelming majority trees are remarkable in different areas. The dust-retention ability of different tree types is in order of broad-leaved shrub evergreen broad-leaved arbordeciduous broad-leaved arbor. The afforest tree species are made to assort at the basis of comprehensive dust retention capacities, the first category includes Ligustrum quihoui, Magnolia grandi flora , Fatsia japonica, Pittosporum tobira , Buxus sinica and Broussonetia papyrifera, the amount of dust retention by those trees surpass 0.4 mg·cm^-2 Ligustrum lucidum Air, Platanus hispanica , Cinnamomum camphora , Prunus cerasi fera , Viburnum awabuki , Lagerstroemia indica, Buxus megistophylla and Ginkgo biloba belong to the second category and which is between 0.2 0.4 mg·cm^-2 the amount of dust retention by Prunus serrulata, Pterocarya stenoptera, Polulus Canadensis, Prunus persica, Robinia pseudoacacia and Acer palmatum is lesser than 0.2 mg. cm-2 and is in the third category.
