摘要
生活性街道作为衔接室内外环境的关键过渡空间,其热环境质量直接影响人体热舒适水平。以天津市和平区为例,综合运用主观问卷调查和客观生理实验方法,结合气象参数及生理等效温度(Physiological Equivalent Temperature,PET),探究街道热环境对人体热舒适的影响机制。结果表明,PET能有效预测热感觉、热舒适、皮肤温度、体核温度、血压及脉搏等生理参数,且热环境会显著影响人体主观感受及客观生理参数。基于此,提出调整绿化环境、改善通风条件等的具体措施,旨在改善高密度城区生活性街道的热环境,提升居民热舒适水平和生活质量。
Living street is a key transitional space between indoor and outdoor,whose thermal environment quality directly affects the level of human thermal comfort.Based on the methods of subjective questionnaire survey and objective physiological experiment,taking the Heping District of Tianjin as an example,the paper investigates the influencing mechanism of street thermal environment on human thermal comfort by meteorological parameters and the Physiological Equivalent Temperature(PET).The results show that PET could effectively predict physiological parameters such as thermal sensation,thermal comfort,skin temperature,body core temperature,blood pressure and pulse,and the thermal environment would significantly affect the subjective sensation and objective physiological parameters of the human body.Based on the results,the paper proposes specific measures on adjusting green environment and improving ventilation conditions,to improve the thermal environment in high-density urban living streets and the residents’thermal comfort level and life quality.
