摘　　要：对福州、厦门市以小叶榕、高山榕、羊蹄甲、樟树、凤凰木、芒果等绿化树种为主的主干道路的总悬浮颗粒物(TSP)浓度、小气候、车流量等进行同步观测,并分析城市绿化树种对TSP浓度的影响。结果表明:城市绿化树种对降低大气中TSP浓度有明显效果;道路中央的TSP浓度明显高于树下;TSP浓度与环境湿度表现为负相关。城市绿化树种降低颗粒物的能力有差异,福州市行道树绿化树种净化能力为小叶榕>芒果>樟树>羊蹄甲;厦门市行道树净化能力为高山榕>芒果>凤凰木>羊蹄甲。The consistency of total suspended particulate （TSP） , microclimate and the volume of the traffics at the same time, survey and analysis on Ficus microcarpa, F. altissima, Bauhinia purpurea, Cinnamomum camphora, Delouix regia, Maugifera indic in Fuzhou and Xiamen have been made where used them as the street trees. The results were as follows ：the different species have significant impact on the consistency of TSP in the air; the consistency of TSP on the road higher than that under the trees; the order of the efficacy of four species in Fuzhou to reduce TSP concentration from high to low was ： F. microcarpa 〉 M. indic 〉 C. camphora 〉 B. purpurea ; the order of the efficacy of four species in Xiamen to reduce TSP concentration from high to low was ： F. altissima 〉 M. indic 〉 D. regia 〉 B. purpurea.
