| Abstract: |
| 【Objective】In order to provide scientific references for the construction of vertical greening landscape in urban parks of Nanning City and other urban green spaces, the vertical greening plant resources in the city parks were investigated.【Method】By means of sample plot investigation, species, life form and other information of plants in 15 urban park vertical greening landscape sample plots of Nanning City were obtained. Combined with professional literature, a list of vertical greening plants in urban parks of Nanning City was compiled, and the characteristics of vertical green plant resources were analyzed.【Result】There are 306 species of vertical greening plants in urban parks of Nanning City, which belong to 95 families and 193 genera. There are five dominant families including Orchidaceae, Leguminosae, Liliaceae, Gramineae and Araceae. There are 35 species, 46 species, 90 species and 135 species of arbor, shrub, liana and herbaceous plants, respectively. The ratio of woody plants to herbaceous plants is about 1∶1.2. The ratio of evergreen woody plants to deciduous woody plants is about 4.75∶1. Flowering plants and color-leafed plants account for 57.19% and 12.75%, respectively. There are 90 species of epiphytes, accounting for 29.41%, and 143 species of native plants, accounting for 46.73%.【Conclusion】The vertical greening plant resources in urban parks of Nanning City is rich, and they are mainly evergreen plants. There are many species of lianas, and the epiphytic landscape is unique. The plant configuration is reasonable and coordinated with the appendages. In view of the problems existing in the application of vertical greening plants in parks, the following suggestions are put forward: vigorously applying native plants to highlight the regional characteristics of the city, enriching the species of coleus plants and increasing the change of landscape colors, and excavating the cultural connotation of plants to reflect the beauty of landscape artistic conception. |
