摘要 |
This study focuses on the three courtyards located in the eastern, central, and western sections of the Tongzhou Campus of Renmin University of China. Adopting a functional differentiation perspective, the research systematically analyzes the patterns of plant diversity within courtyards characterized by distinct functional orientations. This analysis employs various plant species diversity indices, including the Patrick richness index, Simpson dominance index, Shannon-Wiener diversity index, and Pielou evenness index, alongside a classification of functional plant types, namely ornamental, ecological regulation, spatial shaping, and recreational assistance. The results indicate that the east courtyard presents the highest Patrick species richness (S=42), predominantly comprising spatial shaping and recreational assistance plants, which are well-suited for recreational and passage functions. Conversely, the central courtyard exhibits the lowest Patrick species richness (S=19), characterized by a balanced distribution of functional types, with an emphasis on public display and traffic guidance. The west courtyard demonstrates the greatest stability in the tree layer (D=0.87), featuring a combination of shade-tolerant and ornamental plants that fulfill the requirements for a tranquil and naturalistic environment. One-way analysis of variance reveals that only Patrick species richness differs significantly among the courtyards (P=0.007), whereas the diversity index does not show a significant difference. This finding suggests that functional requirements precisely regulate diversity through microhabitat heterogeneity and plant configuration strategies. This study offers both a theoretical foundation and practical guidance for the plant configuration and functional optimization of small-scale courtyards on campus. |
