摘　　要：地面绿地空间的短缺使垂直绿化成为改善热环境的有效途径,为探究垂直绿化对老旧小区微气候和热舒适的影响程度,以老旧小区为研究对象,运用ENVI-met数值模拟技术,使用空气温度(Ta)、平均辐射温度(MRT)和生理等效温度(PET)指标量化分析不同垂直绿化率对微气候和热舒适的影响。结果表明,微气候和热舒适改善程度与绿化率成正比,垂直绿化不仅可以改善水平方向的微气候,对垂直方向也有一定的作用,并可有效提升空间的热舒适水平,整体表现出早晚好于中午的特征。该研究弥补了社区尺度上对垂直绿化改善微环境和热舒适研究的不足,可为老旧小区微气候和热舒适度改善以及相关政府部门制定垂直绿化的推进策略提供参考和依据。Due to the shortage of ground green space,vertical greening becomes an effective way to improve thermal environment.In order to explore the impact of vertical greening on the microclimate and thermal comfort of old residential areas,ENVI-met numerical simulation technology and air temperature(Ta),mean radiant temperature(MRT)and physiological equivalent temperature(PET)indicators were used to quantify the impact of different vertical greening rates on the microclimate and thermal comfort of old residential areas.The results show that the improvement degree of microclimate and thermal comfort is proportional to the greening rate.Vertical greening can not only improve the horizontal microclimate,but also has a certain effect on the microclimate of vertical direction.Besides,vertical greening can also effectively improve the thermal comfort level of the space,of which the overall effect in the morning and evening was better than that at noon.This study makes up for the lack of research on the improvement of microenvironment and thermal comfort by vertical greening at community scale,and provides reference and basis for the improvement of microclimate and thermal comfort in old residential areas and the formulation of vertical greening promotion strategies by relevant government departments.
