To explore the restorative eff ects of plant landscapes on university campuses on the physical and mental health of college students, the study quantitatively analyzes the relationship between the spatial characteristics of plant landscape units and the restoration of students’ physical and mental well-being. The aim is to provide a scientifi c basis for campus plant landscape design and off er optimization recommendations. This study selected 18 plant landscape units with diff erent spatial characteristics on the campus of Shandong Jianzhu University. By measuring physiological indicators (blood pressure, heart rate, blood oxygen saturation, etc.) and psychological indicators (Perceived Restorativeness Scale, Positive and Negative Aff ect Schedule), the restorative eff ects of plant landscapes on college students’ physical and mental health were evaluated. The study found that plant landscape units signifi cantly outperformed classroom and built environments in lowering blood pressure, stabilizing heart rate, and improving blood oxygen saturation. Particularly, spatial features such as herbaceous layer coverage, trunk and branch visibility, canopy coverage, and heightto- crown ratio demonstrated notable restorative eff ects. Based on the fi ndings, this paper proposes recommendations for optimizing campus plant landscape design, including enhancing visual appeal, interspersing restorative plant landscape units, connecting continuous plant spaces, and adding rest facilities to maximize the therapeutic eff ects of plant landscapes on college students’ physical and mental well-being. This study provides a scientifi c basis for plant landscape design in university campuses and holds signifi cant practical implications.
