Blue-green spaces are integral components of landscape architecture and play a vital role in the ecological sustainability of urban environments.The scientific planning and design of landscape tree species are critical to optimizing the multifunctional benefits of blue-green spaces.This study selected 17 tree species suitable for blue-green spaces in Chongqing and evaluated their flood tolerance through a controlled flooding stress experiment.Fourteen growth and physiological indices were measured,encompassing comprehensive growth,water physiology,gas exchange,and chlorophyll fluorescence parameters.Principal component analysis and cluster analysis were employed to comprehensively assess the submergence tolerance of each species.Based on the results,the 17 species were ranked by their submergence tolerance and categorized into four groups:the strongest,relatively strong,relatively weak,and the weakest.These findings provide a scientific basis for the selection and optimization of tree species in urban wetland ecosystems.
