中文摘要：

本文针对岭南庭园夏季热舒适状况进行研究。首先,使用现场实测及问卷调研的方法,获得各气象要素（空气温度、相对湿度、黑球温度、风速）的逐时数据及庭园室外热舒适状况;然后,借助Ray Man模型,计算生理等效温度,综合评析庭园不同景观要素组合空间的热环境情况;最后,采用回归分析法建立岭南庭园室外空间人体热感觉与热环境指标之间的关联并获得PET热中性温度及阈值上限,初步建立岭南庭园室外热舒适评价模型。

英文摘要：

The thermal comfort of Lingnan Garden in summer was analyzed. First of all, the field measurement and questionnaire survey were used to obtain the hourly data of meteorological elements （air temperature, relative humidity, black globe temperature, wind speed）and the state of the garden outdoor thermal comfort. Then, the physiological equivalent temperature （PET） was calculated by means of RayMan model to synthetically evaluate the thermal environment of garden spaces composed of different landscape elements. Finally, the regression analysis method was used to establish the connection between human thermal feeling and thermal environment index in the Lingnan Garden outdoor space and obtain the thermal neutral temperature and maximum temperature of PET and preliminarily establish the outdoor thermal comfort evaluation model.
