摘要: 基于河北省夏季1991—2020年143个国家级地面气象观测站逐日资料以及2014—2020年8个辐射站日数据,以通用热气候指数(UTCI)为评价指标,利用趋势分析法、克里金插值方法揭示了夏季人体舒适度时空分布规律。结果表明:近30 a河北省夏季舒适级占比总体呈减少趋势,趋势值为-0.9%·(10 a)-1,存在空间差异,随着海拔高度降低,舒适级占比趋势倾向率由正转负;平原、丘陵、低山舒适级占比呈单谷形态,高海拔地区则呈单峰形态,四类地形夏季舒适日数分别为24、81、92、92 d,低山、高海拔地区全季均为舒适日数;空间分布总体呈由西北向东南递减趋势,高海拔地区舒适占比最高,达到95.6%,平原舒适占比最低,为33.8%;7月和8月高海拔地区舒适级占比最高,而6月则由于高海拔地区气温仍较低,低山舒适等级占比最高。因此,河北省低山和高海拔区域夏季体感舒适,皆适合出游,平原地区6月上、中旬适宜出游,丘陵地区除7月下旬外适宜出游。

关键词: 通用热气候指数(UTCI), 人体舒适度, 舒适级占比

Abstract: Based on the daily data from 143 national-level surface meteorological observation stations in Hebei Province during the summer months from 1991 to 2020,as well as the daily data from 8 radiation stations from 2014 to 2020,this study takes the Universal Thermal Climate Index (UTCI) as the evaluation indicator.It reveals the spatiotemporal distribution pattern of summer human thermal comfort using trend analysis and Kriging interpolation methods.The results show that over the past 30 years,the proportion of comfortable days in Hebei Province during summer has generally shown a decreasing trend,with a trend value of -0.9% per decade.There are spatial differences: as the altitude decreases,the tendency rate of the proportion of comfortable days shifts from positive to negative.The proportion of comfortable days in plains,hills,and low mountainous areas presents a single-valley pattern,while high-altitude areas show a single-peak pattern.The number of summer comfortable days in these four types of terrain is 24,81,92,and 92 days respectively,with low mountainous and high-altitude areas having comfortable days throughout the entire summer season.In terms of spatial distribution,there is an overall decreasing trend from northwest to southeast.High-altitude areas have the highest proportion of comfortable days,reaching 95.6%,while plains have the lowest proportion at 33.8%.High-altitude areas have the highest proportion of comfortable days in July and August.However,in June,due to the still relatively low temperatures in high-altitude areas,low mountainous areas have the highest proportion of comfortable days.Therefore,low mountainous and high-altitude areas in Hebei Province have a comfortable summer thermal sensation and are suitable for traveling.The plains are suitable for traveling in the first and middle ten days of June,and the hills are suitable for traveling except in the last ten days of July.

Key words: Universal Thermal Climate Index (UTCI), Human Comfort, Comfort Level Percentage
