摘　　要：针对福州市、厦门市以小叶榕、高山榕、羊蹄甲、樟树、凤凰木、芒果为行道树的主干道路进行CO浓度、小气候、车流量的同步测定与分析。结果表明,不同树种对大气中CO浓度水平的影响呈极其显著关系;道路中央CO浓度与车流量有较大的相关性,树下CO浓度与车流量的相关性减小;行道树在一定程度上降低了大气中的CO浓度;福州市4种行道树降低CO浓度从大到小顺序为芒果,樟树,小叶榕,羊蹄甲;厦门市4种行道树降低大气中CO浓度从大到小顺序为凤凰木,芒果,高山榕,羊蹄甲。The consistency of carbon monoxide, the microclimate and the volume of traffic in Fuzhou City and Xiamen City, where Ficus microcarpa, F. altissima, Bauhinia purpurea, Cinnamomum camphora, Delonix regia, Mangifera indic have been grown as the street trees, were tested and analyzed. The results showed that： the different species has very significant impact on the consistency of CO in the air; the consistency of CO on the road has greater relevance with the traffic than that under the trees; the efficafy of the four species in Fuzhou City to reduce CO concentration were M. indic 〉 C. camphora 〉 F. pusillifolia 〉 B. purpurea; the four species in Xiamen City to reduce CO concentration were D. regia 〉 M. indic 〉 F. ahissima 〉 B. purpurea.
