摘　　要：热舒适是影响儿童夏季户外活动的主要方面,树木是改善儿童夏季热舒适的重要影响因素。研究比较了ENVI-met中28个树种对儿童热舒适的调节效应,并分别探索了树木特征因子与SET值降低幅度、对儿童热舒适影响范围的相关性。结果表明:小叶榆、悬铃木、栾树、槐树、云杉、臭椿、合欢、椴树、夏栎对儿童热舒适的改善幅度显著,小叶榆、夏栎、银毛椴等对儿童热舒适的影响范围较大;冠幅和叶面积密度与树下SET值呈线性负相关,树高、冠幅和叶面积密度与树种高温段对儿童热舒适的整体影响范围呈线性正相关。研究进一步揭示了树木与儿童热舒适的内在联系,可为天津市儿童活动场地植物应用提供重要参考。Thermal comfort is the main factor that affects children's outdoor activities in summer,and trees are important factors to improve children's thermal comfort.This study compares the effects of 28 tree species in ENVI-met on children's thermal comfort,and explore the correlation between tree characteristic factors and the reduction of SET as well as the range of influence on children's thermal comfort.The results show that Ulmus parvifolia,Platanus,Koelreuteria paniculata,Styphnolobium japonicum,Picea asperata,Ailanthus altissima,Albizia julibrissin,Tilia tuan,and Quercus robur significantly improve the thermal comfort of children,while Ulmus parvifolia,Quercus robur and Tilia tuan have a large impact on the thermal comfort of children.The canopy width and leaf area density are negatively correlated with the SET value under the tree,and the tree height,canopy width and leaf area density are positively correlated with the overall impact range of the high temperature segment of the tree species on children's thermal comfort.The study further revealed the internal relationship between trees and children's thermal comfort,and provide an important reference for the application of plants in children's playground in Tianjin.
