摘　　要：下沉广场作为城市居民娱乐休闲以及地上地下过渡的重要空间形式,科学分析其热环境特性以及建立热舒适评价模型,对城市高质量发展具有非常重要的意义。本文以天津市典型下沉广场为研究对象,采用现场实测与问卷调查相结合的研究方法,在掌握了下沉广场冬季热环境现状的基础上,总结地上、地下空间热环境各项参数对人体热感觉的影响规律,并且建立了天津市下沉广场冬季热感觉和热舒适评价模型,明确了冬季的热中性温度及舒适区间,通过生理等效温度对比,揭示了下沉广场形态特征对人体热感觉造成的影响程度,旨在为寒冷地区下沉广场的合理设计及优化改造提供理论参考。The sunken plaza is an important space form for urban residents’entertainment and leisure and above-ground and underground transition,and a scientific analysis of its thermal environment characteristics and the establishment of a thermal comfort evaluation model are of great significance to the high-quality urban development.This paper,with the typical sunken square in Tianjin as the research object,combined on-site measurement and questionnaire survey,and summarized the rules of the influence of various parameters of the thermal environment of the above ground and underground space on the human thermal sensation based on the general understanding of the current situation of the winter thermal environment of the sunken plaza.An evaluation model of the winter thermal sensation and thermal comfort was established for the sunken plaza in Tianjin,defining the thermal neutral temperature and comfort range in winter.Through the comparison of physiological equivalent temperature,this paper revealed the influence of the morphological characteristics of sunken plaza on human thermal sensation,providing theoretical reference for the design and transformation of sunken plaza in cold areas.
