快速城镇化和全球变暖使城市室外环境的热不舒适加剧，热安全风险提高。为了解人体在室外动态热环境中生理量的变化规律，为快速评价室外热环境提供依据，开展了室外环境中人体热反应观测实验，对二节点模型进行了模拟精度分析和吻合度检验，从皮肤温度、体核温度调定点，人体标准输入模型，人体启动体温调节的环境温度值和人体与环境的对流换热系数等四个方面对二节点模型进行了修正，得到了适应于室外人体热反应预测的人体二节点修正模型及修正方法。

Because of rapid urbanization and global warming, urban outdoor thermal discomfort and risk of thermal safety increased. In order to find out the physiological parameters changes of human body in outdoor thermal environment, provide a basis for rapid urban thermal environment evaluation, carried out the human thermal response measurement, then analyzed the simulation accuracy and coincidence degree of the two node model, found out that changes of environment which human in and human activity on human physiological parameters. Based on set-point of skin temperature and core temperature, standard human model, temperature of regulation starting, convective heat transfer coefficient, the two-node model was verified and revised, and a new two-node model for predicting outdoor human thermal response was developed.
