Study on Landscape Plant Investigation and Application in Nanning Parks

Methods of on-site investigation and data collection were used to study landscape plants in 19 parks of Nanning. The characteristics of application and improvement suggestions for landscape plants in each place were analyzed from the aspects of plant species, living form, being native or foreign, ornamental features, rare or endangered and toxic type and so on. The results indicated that there were plentiful species in Nanning parks which belonged to 115 families, 359 genera and 549 species. Among them, the native and evergreen plants were used widely. The tropical plants landscape was obvious. There were many flowers and fruits throughout the year and the flowering plants were everywhere. But some types of plants were used fewer and concentrated in a certain place such as vines, aquatic plants and rare and endangered trees and so on. The toxic landscape plants were used commonly and the old and famous trees were deficient. So some suggestions were proposed such as increasing applications of vines, aquatic plants and the rare and endangered plants, adding signs for the toxic plants and increasing human activities regarding to plants.
