摘要
为探索夏热冬冷地区大学校园室外热舒适环境的空间优化策略,本文以上海某大学为研究对象,对大学校园典型空间形态条件下的气象参数进行现场实测,同时结合大学生受试者的热舒适问卷,利用Rayman软件计算出受试者的生理等效温度(Physiological Equivalent Temperature,PET)。为获得全校园范围的温湿度分布,本研究进行了温湿度移动测量并对数据进行时间修正与空间插值,之后对通过以上方式获取的校园范围温湿度与地表形态特征参数进行相关性分析。结果显示,该大学校园夏季大学生“热中性”的PET值为30.60℃,PET指标与空气温度、相对湿度之间分别呈现负相关与正相关,且空气温度与PET指标的相关程度更高;天空角系数与透水表面比率对空气温度具有显著的正相关,街道峡谷高宽比、建筑密度、平均建筑高度与空气温度之间则出现显著的负相关。以上结果说明进行校园建筑和景观规划设计时可通过合理设计地表形态特征的方式缓解空气温度的上升,以达到提升学生热舒适的目的。该研究可为夏热冬冷地区大学校园室外空间规划提供优化参考,有助于改善校园热舒适环境。
In order to explore the spatial optimization strategy of outdoor thermal comfort environment of university campus in hot summer and cold winter regions,a university in Shanghai was taken as the research object,and field measurement of meteorological parameters conducted under typical spatial morphology conditions of university campus.At the same time,combined with the thermal comfort questionnaire of college students,the physiological equivalent temperature(PET)of the subjects was calculated by using Rayman software.This study performed temperature and humidity movement measurement,time correction,and spatial interpolation of the data to obtain the temperature and humidity distribution of the entire campus,and then the correlation between the temperature and humidity of the campus and the characteristic parameters of the surface morphology were analyzed.The results showed that the“neutral”PET value of university students in summer was 30.60℃,and PET index was negatively correlated with air temperature and positively correlated with relative humidity,and air temperature was more correlated with PET index.The sky view factor and pervious surface fraction have a significant positive correlation with air temperature,and there is a significant negative correlation between aspect ratio,building surface fraction,height of roughness elements and air temperature.In the planning and design of campus building and landscape,the rise of air temperature can be alleviated by reasonably designing the surface morphological characteristics,with the goal of enhancing students'thermal comfort.This study can provide an optimized reference for the outdoor space planning of university campus in hot summer and cold winter regions,which is helpful to improve the thermal comfort environment of campus.
