Abstract:
In this study, plant resources of 2,408 road green spaces and 312 park green spaces in Guangzhou were investigated, and the application status and characteristics of garden plants in Guangzhou were analyzed. The results showed that there were 1,020 species of vascular plants. belonging to 549 genera and 159 families. There were 409 species of trees, 305 species of shrubs, 306 species of herbs and lianas, accounting for 40.10%, 29.90% and 30.00% of the total plant species, respectively. From the floristic composition of plant families and genera, the distribution characteristics of common vascular plants in Guangzhou were obvious in tropical and subtropical regions. There are 441 native plants in common use, accounting for 43.23% of the total plant species, and native plants still have a large potential for exploitation. The species of flowering plants were abundant, accounting for 29.22% of the total plant species. Compared with other cities in South China, there were 169 species of color leaf plants, accounting for 16.57%. There are abundant ancient and famous trees, with 9,940 trees of 100 species in 41 families. There are 29 species of invasive plants, among which Sphagneticola trilobata and Lantana camara are widely used as ground cover plants. This survey provides more comprehensive basic data for the application of garden plants in Guangzhou in recent years, and puts forward suggestions for the future application of garden green plants in Guangzhou.
