摘要
本文应用温湿指数（THI）指标对上海市夏季7、8月份高温期的热环境及其对人体舒适度的影响进行了初步的研究评价。温湿指数综合考虑了温度和湿度两个因子对人体热感的影响，比单纯的温度指标更为合理。根据上海市的1987～1991年夏季的观测资料，7、8月份以湿热为特征，较高的相对湿度促使THI增大，增加了热不舒适感。以THI≥29．5作为酷热的标准是合理的，上海市夏季的酷热日数比按日Tmax≥35°的高温日数显著增加，这说明了相对湿度对人体舒度有强烈影响。酷热日发生时日最高温度下限为33℃。
The thermal comfort of Humans is the result of the synergistic of several components of the environment, such as temperture, humidity, wind, solar radiation and some orther weather elements. So,it is not suitable using the temperature only to indicate the hot degree in summer. In this paper, THI index is applied to study the reation of human comfort with temperature and humidity in Shanghai summer. By the index, it is find that Shanghai Summer is characterisaticed with moisture thermal feature, which contribute mainly to the high temperature and humidity. The high THI, which causes the extremely discomfort time lasting longer in shanghai summer.
