The waterlogging tolerance in landscape plants serves as a critical selection criterion for optimized species screening in riparian landscaping.In the summer of 2023,a systematic field survey was conducted to assess the flood damage to 105 species(including cultivars)of landscape plants in the downstream flood storage areas,representing 39 families and 74 genera,following the controlled reservoir discharge from Shisanling Reservoir in Changping District,Beijing.The survey involved photographic documentation and written records of the growth vigor of the landscape plants.The waterlogging tolerance of the common landscape plant species in North China was stratified through comparative and inductive analysis.The results showed that:1)12 plants,such as Salix babylonica and Fraxinus chinensis,were most tolerant to waterlogging;2)13 plants,such as Diospyros kaki and Acer rubrum,were more tolerant to waterlogging;3)15 plants,such as Hibiscus grandiflorus and Iris lactea,were intermediately tolerant to waterlogging;4)15 plants,such as Pinus tabuliformis and Juniperus sabina,were less tolerant to waterlogging;5)50 plants,such as Helianthus annuus,Muhlenbergia capillaris,and Rhus typhina,were found to be least tolerant to waterlogging.Distinguishing the differences in waterlogging tolerance among plant species can provide a scientific basis and practical reference for the construction of waterfront parks and the selection of plant species in North China,as well as for landscape greening management.
