| 利用1961-2017年成都市西部邛崃国家气象观测站日平均气温、日最高气温、日平均风速、日平均相对湿度和日最小相对湿度计算逐日人体舒适度指数及白天和夜间舒适度指数,并通过线性倾向估计方法分析近30年邛崃市人体舒适度变化特征。结果表明：近30年邛崃市没有暑热和寒冷天气,人体舒适度日数舒适级别日数最多,其次是冷不舒适级别日数,热不舒适级别日数最少；年平均人体舒适度指数呈现较小的上升趋势；舒适日数集中在春季、夏季、秋季三个季节；热不舒适日数和舒适日数21世纪初期相比20世纪90年代有所增加,冷不舒适日数有所减少；近30年白天人体舒适度指数有着较明显的升高趋势,夜间人体舒适度指数变化不大。 |

| Abstract: |
| Based on the observation data of national meteorological observatory of Qionglai City in Chengdu from 1991 to 2020 to calculate human comfort index ,the meteorological elements include daily average temperature, daily average wind speed and daily average relative humidity. Using the linear trend method to analysis the change characteristics of human comfort in Qionglai City for the past 30 years. The results are as follows:(1) In recent 30 years, the number of days of comfort level is the most, followed by the number of days of cold discomfort level and the number of days of hot discomfort level is the least. There is no extreme hot and cold weather. (2) The number of comfortable days is concentrated in spring, summer and autumn. From the 1990s to the early 2000s, the number of thermal discomfort days and comfortable days increased and the number of cold and uncomfortable days decreased. (3) The human comfort index increased obviously in the daytime, but changed little at night. |
