摘　　要：以天津空港经济区主要绿化树种为研究对象,通过实地采样调查和实验室分析,对20种绿化树种的滞尘能力进行初步研究。结果表明:灌木树种的单位叶面积滞尘能力整体大于乔木;而9种乔木单位叶面积滞尘能力大小顺序为毛白杨>国槐>泡桐>青桐>悬铃木>刺槐>栾树>旱柳>白蜡;11种灌木中单位叶面积滞尘能力大小顺序为紫丁香>棣棠>珍珠梅>水腊树>西府海棠>木槿>紫叶李>紫叶矮樱>金银木>金叶接骨木>紫荆。乔木单株滞尘能力大于灌木,9种乔木单株滞尘量大小顺序为刺槐>悬铃木>国槐>青桐>毛白杨>旱柳>白蜡>泡桐>栾树,11种灌木单株滞尘量大小依次为:紫叶矮樱>珍珠梅>棣棠>金银木>紫丁香>水腊树>木槿>紫叶李>西府海棠>金叶接骨木>紫荆。This study conducted a preliminary research on the dust detentions and dust efficiency of 20 greening tree species by field sampling investigating and laboratory analyzing. The 20 greening tree species in Tianjin airport economic area,a new industrial zone of Tianjin,was taken as the research object. The results indicated that the dust- retentions unit leaf area of 9 trees were ranked as follows,Populus tomentosa Sophora japonica Paulownia fortunei Firmiana simplex Platanus acerifolia Robinia pseudoacacis Koelreuteria paniculata Salix matsudana Fraxinus chinensis. The descending order of dust- retention ability in 11 shrubs was as follows： Syringa oblata Kerria japonica Sorbaria kirilowi Ligustrum obtusifolium Malus micromalus Hibiscus syriacus Prunus cerasifera Prunus × cistena Lonicera maackii Sambucus canadensis var. aurea Cercis chinensis. Besides,the total dust- retention ability of tree species is different. The above- mentioned results are also useful for the new industrial zone of northern China with similar atmosphere.
