Analysis of Landscape Plant Diversity: A Case Study in the Yuanbo Garden

Abstract

The diversity of park plants and the application status of landscape plants reflect a region’s species diversity as well as the achievements in urban environmental planning and park construction. This study investigated the landscape plant diversity and plant communities in the Yuanbo Garden of Songming Vocational Education Park in Kunming through field surveys. The results show that the garden contains 31 species from 31 genera and 22 families, including 10 tree species (9 families, 10 genera), 9 shrub species (7 families, 9 genera), and 12 herbaceous species (9 families, 12 genera). Herbaceous plants are the most abundant, followed by trees and shrubs, indicating rich plant diversity. Native Yunnan species account for 30% of the total, maintaining stable ecological niches and providing habitats for local biodiversity; naturalized alien species comprise 17%, posing low threats and often coexisting with native species; controlled introduced species represent 20%. Nevertheless, ecological risks from high-risk alien species require attention.
