| 摘 要： | 利用四川省156个国家气象站1980~2020年逐日观测资料、2018~2020年逐时观测资料和3DCloudA总云量格点数据，计算逐日和逐时通用热气候指数（Universal Thermal Climate Index，UTCI），以UTCI介于9~26℃为室外热环境舒适状态的判定标准，在统计分析各站点年均UTCI值、年均舒适日数、月均舒适日数及日均舒适小时数的基础上，研究了四川地区舒适度区划。结果表明:盆地大部分地区为夜间舒适和春秋舒适；阿坝州南部、甘孜州西部和凉山州北部为日间舒适和夏季舒适；攀西地区南部总体呈现全天和冬季舒适的特征；甘孜州北部、中部和阿坝州北部均表现为人体不舒适的特征。

| Abstract: | Based on the daily meteorological observation data, the hourly meteorological observation data and the total cloud cover grid data of 3DcloudA of 156 national meteorological stations in Sichuan province from 2018 to 2020, the daily and hourly UTCI are calculated. Taking the UTCI between 9℃ and 26 ℃ as the comfort state of outdoor thermal environment, the comfort zoning of Sichuan area is studied on the basis of statistical analysis of the average annual UTCI value, the average annual comfort days, the average monthly comfort days and the average daily comfort hours of each station. The results show that most parts of the Basin are comfortable at night and in spring and autumn. In southern Aba, western Ganzi and northern Liangshan, daytime and summer are comfortable. The southern part of Panxi area generally presents the characteristics of all-day and winter comfort. The northern part of Ganzi, the central part and the northern part of Aba are characterized by human discomfort. |
