Study on synergistic change strategies of leaf functional traits of common garden plants along the urban–rural gradient—Suzhou, China
摘要
The study of changes in landscape plant responses along the urban–rural gradient can better inform plant allocation strategies to mitigate the ecological risks associated with rapid urban development. This study focused on the trait changes of 10 common garden plants along the urban–rural gradient in Suzhou, selecting 12 leaf functional traits for the investigation to provide a quantitative basis for decision-making and landscape plant management practices. The results showed that: (1) six leaf functional traits, including specific leaf area (SLA), stomatal conductance (Gs), transpiration rate (Tr), leaf nitrogen content per unit of mass (Nmass), leaf potassium content per unit of mass (Kmass), and stomatal size (SS), differed significantly along the urban–rural gradient; (2) the variability and variance characteristics of leaf functional traits varied along the urban–rural gradient among different plants and growth forms; (3) the synergistic changes in leaf functional traits of different garden plants, driven by the urban–rural, differed, which can be further explored to understand plant adaptive strategies in various environments and guide garden plant selection.
