摘　　要：为了解城市道路不同绿化树种的滞尘能力,筛选具有良好滞尘效应的道路绿化树种。以延安市区三条主干道9种乔、灌木行道树为研究对象,采用质量差值法测定不同树种滞尘能力。结果表明:绿化树种叶片滞尘能力差异较大(p<0.05)。丁香、银杏、大叶黄杨、油松的单叶滞尘能力相对高,而国槐、金叶女贞、紫叶小檗的滞尘能力相对较低,乔木单叶滞尘能力显著高于灌木。紫叶小檗、油松、大叶黄杨、刺槐、丁香的单位叶面积滞尘能力相对高,而银杏、国槐、新疆杨的滞尘能力较低,落叶灌木和常绿乔木的单位叶面积滞尘能力显著高于落叶乔木。在延安市城市绿中可以考虑紫叶小檗、油松、大叶黄杨、刺槐、丁香等滞尘能力强的树种。In order to explore the dust-retention capacity of the greening species along the city road and select those with excellent dust retention effect for those roadside planting.9 plant species were selected as the experimental objects,including deciduous broad-leaved trees and shrubs and evergreen trees along three city ways in Yanan city.The dust-retention capacity of these plants was recorded by weight difference method.The results showed that the dust retention capacity of leaves for different trees was significantly different(p<0.05),and the dust retention capacity of individual leaves from Syringa oblata,Ginkgo biloba,Euonymus japonicus and Pinus tabuliformisis relatively high,while that of Sophora japonica,Ligustrum vicaryi and Berberis thunbergiais relatively low.The dust retention capacity of individual leaves from arbors were significantly higher than those of shrubs.The dust retention capacity of individual leaves from Berberis thunbergia,Pinus tabuliformis,Euonymus japonicus,Robinia pseudoacacia and Robinia pseudoacacia is relatively high,while that of Ginkgo biloba,Sophora japonica and Populus alba is relatively low.The dust retention capacity of deciduous shrubs and evergreen arbors are significantly higher than those of deciduous arbors.Berberis thunbergia,Pinus tabuliformis,Pinus tabuliformis,Pinus tabuliformis and Syringa oblata have excellent dust retention capacity could be considered as greening species in Yanan city.
