摘　　要：本文以北京市白塔寺片区为研究对象,通过热舒适度评测研究,从人体感知角度评价分析北京老城区公共空间环境质量,并推导评测结果与公共空间形态的关联性,为老城区环境改善提出建议。评测研究利用ENVI-met软件平台,基于现状监测数据与模型数据的验证拟合,建立白塔寺片区6条胡同的小气候动态模型,主要模型指标包含温度、湿度、太阳辐射、风速风向。基于以上模型,利用RAYMAN软件计算生理等效温度指数(PET),以获得热舒适度评测结果。在此基础上统计分析6条具有典型空间特征的胡同高宽比、绿化覆盖率,并与热舒适度评测结果进行比较,提出老城区公共空间热舒适度的可能影响因素及改善策略。The paper studied the quality of public space in Baita Temple area in Beijing through thermal comfort evaluation from the perspective of human perception evaluation,and analyzed relevance between the evaluation results and public space to put forward suggestions for improving the old city environment.Based on the verification and fitting of present monitoring data and model data,the research established microclimate dynamic model for six alleys in Baita Temple area by using Envi-met software platform.The main model indexes included temperature,humidity,solar radiation,wind speed and wind direction.Then the research calculated PET(physiological equivalent temperature)index by using RAYMAN software to obtain the results of thermal comfort evaluation.On the basis of microclimate analysis,a comprehensive analysis was given in the paper between the thermal comfort evaluation results and high aspect ratio and green coverage rate in six alleys,the paper proposed possible factors to effect the thermal comfort in the old city public space and improvement strategies for microclimate.
