| 摘 要： | 在贵州冬季相对湿度大、风速小的气候背景下,综合考虑气温和相对湿度对人体舒适度的影响,计算并讨论了9个市州代表站人体舒适度指数IHC及其对温湿环境的响应,发现贵州省冬季低温、高湿对IHC指数具有负贡献,其中气温的高低对IHC指数影响尤为明显,并且在平均相对湿度越高的环境下,IHC指数对平均气温的变化就具有越高的敏感性,因此在贵州省西部和北部地区冬季由于平均气温较低、加之平均相对湿度较大,人体舒适感降低尤为明显。从回归方程出发,讨论贵州省冬季△IHC对△T=1σ或△RH=1σ变化的响应,发现平均气温是影响IHC指数变化的主要指标,而相对湿度作为辅助指标对IHC指数有着增大或减小的调节作用。通过分析IHC指数的稳定持续性,发现其能有效客观的表征出贵州省低温的持续性特征,并且能反映出在平均相对湿度较高的环境下,人体感觉的不舒适持续日数增加,即加大了人体的不舒适感。

| Abstract: | Under the background of high relative humidity and small wind speed in winter of Guizhou, the index of human comfort, IHC, and its response to surrounding temperature and humidity were worked out and discussed in 9 stations by considering the effects of temperature and relative humidity on human comfort. The results show that ： Low temperature and high humidity have negative contributions for IHC index, where in the level of temperature is particularly evident. And the higher average relative humidity of the site there is, the higher sensitivity of IHC index will be brought in by the variation of average temperature. Therefore, due to a lower average temperature, coupled with higher average relative humidity, body＇ s comfort goes down especially in the western and northern regions of Guizhou Province in winter. From the equation, the response of A IHC＇ s variation is discussed at△T=1σ or △RH=1σ, to find that the average temperature is the main indicators to influence IHC index changes, and the relative humidity, as a secondary indicator, has regulation for its increase or decrease. By analyzing the stable continuity of IHC index, to find that its effective is able to objectively characterize sustained characteris- tics of low temperature in Guizhou Province, and to reflect that in a higher average relative humidity environment, the lasting days of uncomfortable feeling increase, which increase the body＇ s discomfort. |
