Abstract:: Based on the investigation of the lines and 30 typical quadrats,the situation of the plant species diversity on the road green space in Guangzhou was systematically analyzed.The results showed that 485 kinds of plants were recorded,which belonged to 111 families and 322 genera.The recorded plants accounted for 23.3% of the total ornamental plants of Guangzhou,in which the ratio of trees,shrubs and herbs was 1.0∶1.0∶1.5,and the shrubs was limited.Furthermore,the native plants had 286 species (59% of the total number of species),which were more than the species of the exotic plants(199 species),but less widely used than the exotic species.Another important observation was that invasive plants had 28 species and some invasive herbaceous plants had a high importance,which leaded to some harmful impaction for the ecosystem.The floristic geographical elements study showed that the plants had clear tropical and subtropical characteristics.Finally,based on the observations concluded from this study,some suggestions were presented to improve plants landscape for road greening in Guangzhou.
