摘要
开展景观植物对人体热舒适度影响的研究对于优化景观设计和园林绿化植物配置具有一定的理论指导意义。在验证ENVI-met模拟精度的基础上,以南京市寒冷季节为气候背景,选取南京市6个不同规格常绿及落叶乔木、灌木树种进行微气候效应模拟,通过Rayman平台计算其热舒适PET值,分析与空地对照组的差异性及影响规律。结果表明,寒冷季节植物对PET有不同程度提升作用。其中乔木对PET影响白天强于夜间,常绿小乔木强于其他乔木,但乔木对PET的影响整体上不显著。寒冷季节灌木对PET影响强于乔木,整体上白天强于夜间,常绿灌木强于落叶灌木。常绿灌木对PET的影响程度与灌木高度呈负相关,与叶面积密度(LAD)和郁闭度呈正相关。
Conducting research on human thermal comfort by landscape plants is of theoretical guiding significance ce for optimizing landscape design and ornamental plant allocation.On the basis of verifying the accuracy of ENVI-met simulation, the microclimate effects of 6 vegetation types with different sizes including trees and shrubs were simulated.The PET(physiological equivalent temperature) value of the experimental groups were calculated by Rayman platform, and the difference between the experimental groups and the control group was analyzed.The results showed that vegetation could improve PET value with different degrees in cold season.Among them, the influence of arbor tree species on PET value in daytime was stronger than that at night, and evergreen small tree species was stronger than the others, but the effect of arbor tree species on PET value was not significant.The effect of shrub tree species on PET value was stronger than that of arbor tree species, evergreen shrub species was stronger than that of the deciduous shrub species.The effect of evergreen shrub species on PET value was negatively correlated with shrub height, and positively correlated with leaf area density(LAD) and canopy density.
