本研究的目的是确定室外热基准的遮荫空间在Xi的城市公园（中国）。气象测量在冬季和夏季进行了主观热感觉问卷调查。采用通用热气候指数（UTCI）对Xi地区的热舒适范围进行了定量分析，并比较了Xi与其他气候带室外热基准的变化。结果表明：（1）气温和地球仪温度是影响Xi室外热舒适的主要物理因子。(2)凉亭遮阳有效地降低了热应力，在冬季和夏季将UTCI降低了15.5和10.1 °C。(3)落叶乔木遮荫是最佳的遮阳设计措施，能够满足热舒适环境的要求。(4)Xi的中性UTCI为23.1 °C，可接受的UTCI范围为18.0 ~ 29.1 °C。（5）冬季16：00 h后，“强冷应激”或更强冷应激发生。夏季亭、落叶树荫为“中性热胁迫”24 h。研究结果确定了热基准，可以帮助城市设计师在中国寒冷地区的城市公园创造热舒适的室外空间。
This study aims to identify outdoor thermal benchmarks of shaded spaces in an urban park in Xi'an (China). Meteorological measurements were conducted during winter and summer accompanied by a subjective thermal sensation questionnaire. The Universal Thermal Climate Index (UTCI) was applied to quantitatively analyze the thermal comfort range in Xi'an, and then variations in outdoor thermal benchmarks between Xi'an and other climatic zones were compared. Results demonstrated that: (1) Air temperature and globe temperature were the dominant physical factors affecting outdoor thermal comfort (OTC) in Xi'an. (2) Pavilion shade effectively lowered thermal stress, decreasing UTCI by 15.5 and 10.1 °C during winter and summer. (3) Deciduous tree shade was the optimal shading design measure and could meet demands for thermally comfortable environments. (4) The neutral UTCI in Xi'an was found to be 23.1 °C, and the acceptable UTCI ranged from 18.0 to 29.1 °C, and (5) a thermal comfort calendar for shaded spaces demonstrated that “strong cold stress” or higher occurred after 16:00h in winter. Pavilion and deciduous tree shades were “neutral thermal stress” for 24h in summer. The results identify thermal benchmarks that could help urban designers create thermally comfortable outdoor spaces in urban parks within the cold region of China.
