摘　　要：为揭示夏季湿热地区城市室外人行空间行人和骑行者的热舒适特点及热环境需求,通过实验观测及问卷调查相结合的方法,对人行空间的热环境水平,行进中的行人和骑行者的热感觉、热舒适、热环境偏好及热接受度进行了统计和相关性分析。分析结果表明,随着人行空间阴影率的变化,行人的热感觉变化比骑行者更敏感,舒适性水平低于骑行者;行人和骑行者的不舒适因素主要为过大的太阳辐射和过高的温度,SET*值越低,行人和骑行者感觉越舒适。使用者对夏季人行空间的热环境需求,行人为SET*≤30.2℃,对应热感觉TSV≤1.4;骑行者为SET*≤32.9℃,对应热感觉TSV≤1.5,行人和骑行者的热舒适状况和热需求存在一定的差异,遮荫率越小,差异越大,行人对热环境的要求更高。To reveal the thermal comfort characteristics and thermal environment requirements of outdoor pedestrians and cyclists in hot and humid areas in summer,the methods of environmental parameters testing and questionnaire survey was used to investigated the thermal environment status,thermal comfort,thermal environment preference and thermal environment acceptability of pedestrians and riders,then correlation analysis was carried out.The results show that with the change of shading rate,thermal sensation of pedestrians are more sensitive than that of cyclists,and the comfort level is lower than that of cyclists.The main uncomfortable factors are excessive solar radiation and temperature.The lower the SET*value,the more comfortable pedestrians and cyclists feel.The thermal requirement for pedestrians is that SET*≤30.2℃,TSV≤1.4,for cyclists SET*≤32.9℃,TSV≤1.5,Pedestrians have higher requirements for thermal environment.
