摘　　要：利用汾河流域1991-2021年的逐日气象观测资料,采用人体舒适度指数(IBC)、Mann-Kendall突变检验、线性趋势等方法计算分析流域内气候舒适度时空分异特征.结果表明:从时间变化情况看:1)1991-2021年汾河流域年气候舒适度以清凉为主,并逐渐向偏凉发展.一年中,6、7、8月份的舒适等级为5级,最为舒适.2)汾河流域年均冷日数(1~3级)为183 d,呈降低趋势;年均舒适日数(4~5级)为180 d,呈增加趋势;年均热日数(7~8级)为2 d.一年中5月到9月舒适日数最多,11月到3月冷日数最多,仅7、8月出现热日数.从空间变化情况看:3)1991-2021汾河流域气候舒适指数及年舒适日数均表现为流域下游>中游>上游;一年中,冬夏两季流域内整体舒适度差异不大,春秋两季气候舒适日数均表现为自北向南舒适日数逐渐增加.Using daily meteorological observation data from the Fenhe River Basin for the years 1991-2021,and employing methods such as the Human Comfort Index(IBC),the Mann-Kendall abrupt change test,and linear trend analysis,this study calculates and analyzes the spatiotemporal differentiation characteristics of climate comfort in the basin.The results indicate the following:In terms of temporal changes:1)From 1991 to 2021,the annual climate comfort in the Fenhe River Basin was mainly cool,gradually shifting towards a cooler state.Within a year,June,July,and August have a comfort level of 5,being the most comfortable.2)The basin's annual average cold days(levels 1~3)are 183 d,showing a decreasing trend;the annual average comfortable days(levels 4~5)are 180 d,showing an increasing trend;and the number of hot days(levels 7~8)per year is 2 d.From May to September,there are the most comfortable days in a year,with the most cold days from November to March,and only July and August experiencing hot days.Regarding spatial variations:3)From 1991 to 2021,both the climate comfort index and the annual number of comfortable days in the Fenhe River Basin show the downstream area>midstream area>upstream area.Throughout the year,there is little overall comfort difference within the basin in winter and summer,while in spring and autumn,the comfort level increases gradually from north to south.
