Frequent snowfall during winter and early spring has led to a substantial increase in the use of deicing agents, causing serious damage to roadside vegetation. Although numerous studies have examined the visible and physiological stress responses of plants to deicing chemicals, limited attention has been given to the relationship between planting cross-sectional drainage structures and plant growth.
Accordingly, this study experimentally investigated the interaction between salinity and drainage layers using three planting cross-section types: a conventional roadside vegetation profile (Case 1), a sand-based section with an additional drainage layer (Case 2), and a crushed-stone drainage section (Case 3). In addition, four groundcover plant species (Hosta longipes, Mukdenia rossii, Hemerocallis fulva, and Allium senescens) were evaluated to identify salt-tolerant species based on their physiological and biochemical responses to varying concentrations of calcium chloride (CaCl₂) using principal component analysis (PCA).
Based on the experimental results, this study proposes an optimal planting cross-section design for roadside green belts, with the aim of reducing trial and error in future projects and providing cost-effective construction guidelines.
