    摘要:为揭示高密度地区广场不同冠层与热环境间、人体热舒适度与行为活动间的关联特征,以上海创智天地广场为研究对象,对小气候要素进行冬夏两季昼夜连续监测。研究冬夏季不同太阳方位角和高度角对场地阴影的影响,解析不同冠层在空间和时间两个维度上的组间差异、冬夏差异,并归纳其作用规律。通过对比行为注记与人体热舒适度数据,分析空间热舒适度对广场单位面积人流量的作用规律,并据此提出小气候适宜性广场的设计策略。

    Abstract:In order to reveal correlation between canopy of square in dense habitat and thermal environment, between human thermal comfort (HTC) and human activities, the micro-climate factors were continuously monitored during summer and winter in Shanghai Knowledge and Innovation Community Square (KIC Square). The variations of shade in the solar elevation angle and solar azimuth in summer and winter were described, and the difference experimental and control groups, difference between summer and winter in a variety of square canopy groups and their diurnal variation were analyzed. The mechanism of how HTC impacts unit area pedestrian volume was obtained on the basis of contrasting behavior mapping data with HTC data, and the influence factors of HTC was revealed. Furthermore, micro-climate adaptive design strategies were proposed for future square planning.
