感知控制对湿热地区户外庭园空间热舒适性的影响——以华侨大学“世外·花缘”生活实验室为例

户外热舒适对城市景观空间的使用具有显著影响。目前对户外热舒适的研究较少考虑感知控制(Perceived Control)的影响作用。通过在选定实验区域内对志愿者进行问卷调查，分析感知控制对庭园空间热舒适的影响。结果表明：1)感知控制对湿热地区庭园空间的夏季中性温度具有一定影响，但对秋、冬季中性温度影响微弱；2)感知控制受限会导致热感觉的敏感程度增强，热舒适范围变窄；3)在中性温度范围附近，感知控制对热舒适感的影响十分微弱，而在热感觉为“冷”“凉”“暖”“热”的热环境中，感知控制对不适感具有一定缓解作用；4)感知控制在一定程度上扩大了人们对庭园热环境的可接受范围，当感知控制受限时，人们对热环境的接受度会有所下降。

The Influence of Perceived Control on the Garden Thermal Comfort in Hot and Humid Areas: A Case Study of Shiwai Huayuan Living Lab in Huaqiao University

Outdoor thermal comfort has a significant impact on the use of urban landscape space. At present, the research on outdoor thermal comfort seldom considers the influence of perceived control. This paper analyzes the effect of perceived control on garden thermal comfort through the questionnaire survey conducted by volunteers in selected experimental areas. The results show that: 1) Perceived control has a certain influence on the garden neutral temperature in summer in hot and humid regions, but has a weak influence on the neutral temperature in autumn and winter. 2) Restricted perceived control will increase the sensitivity of outdoor thermal sensation and narrow the thermal comfort range. 3) In the vicinity of the neutral temperature range, the perceived control has no significant influence on the outdoor thermal comfort, while in a thermal environment where the outdoor thermal feeling is "cold", "cool", "warm", and "hot", the perceived control has a certain relief effect on the discomfort. 4) Perceived control expands the acceptable range of people''s garden thermal environment to a certain extent. When the perceived control is limited, people''s acceptance of the thermal environment will decrease.
