摘　　要：蓝绿空间是风景园林的核心组成部分,对立地生态可持续发展具有重要意义,而园林树种的科学规划与设计是蓝绿空间功能综合发挥的关键因素。选取重庆市蓝绿空间适生的17种园林树种,通过淹水胁迫试验,测定其综合生长、水分生理、气体交换和叶绿素荧光等共14项生长和生理指标,并采用主成分分析和聚类分析综合评价各树种的耐淹能力。17种树种按照耐淹性强弱可分为最强、较强、较弱、最弱4种类型。研究结果可为城市湿地生态系统树种选择与优化提供依据。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.
