摘　　要：热舒适指标作为表征室外空间舒适程度的主要依据,其在不同气候区的适用性是影响室外热环境评价结果的关键因素,为了分析不同热舒适指标在中国严寒地区城市室外空间的适用性,以哈尔滨市大学校园室外空间为例,通过气象参数实测和问卷调查的方式,获得了校园典型空间中受访者的主观热感觉投票和微气候参数,并选取3个统计指标和2个定性指标作为室外热舒适指标的适用性量化指标,对比分析了标准有效温度SET^(*)、生理等效温度PET、通用热气候指标UTCI对寒地大学校园室外空间热舒适的预测性能。PET的预测力和表现力较好,其总体预测和分类预测准确度均较高且Spearman相关分析表明PET的预测值与受访者真实热感觉值相关性较强。在冬季寒地校园热环境评价时应优选PET作为预测指标,SET^(*)和UTCI可作为参考评价指标。The thermal comfort index is the main basis to express the comfort degree of outdoor space,and its applicability in different climate areas is the key factor to affect the results of outdoor thermal environment evaluation.In order to analyze the applicability of thermal comfort indices on campus in winter in severely cold area,this paper takes the outdoor space of Harbin University as an example,through the measurement of meteorological parameters and questionnaire survey.The subjective heat feeling voting and microclimate parameters of the interviewees in the typical campus space were obtained.Three statistical indexes and two qualitative indexes are selected as the applicable quantitative standards of outdoor thermal comfort index.The prediction performance of physiological equivalent temperature(PET),standard effective temperature(SET^(*)) and universal thermal climate index (UTCI) for outdoor thermal comfort of cold university campus is analyzed.The prediction and performance of PET are better than others,and its overall prediction and classification prediction accuracy are the highest and the Spearman correlation coefficient is also the highest.PET should be the first choice evaluation index of outdoor thermal environment in severely cold area,SET^(*) and UTCI can be used as reference evaluation indexes.
