摘    要:利用1960—2005年京津冀地区66个地面气象站气候资料日值数据集,基于人体舒适度指数和风寒温度模型,分析京津冀地区人体舒适度时空特征,计算了京津冀地区春、夏、秋、冬季各站逐日人体舒适度指数和冬季风寒温度。通过人体舒适度指数聚类分析得出人体舒适度指数分区,在此基础上探讨各分区具有代表性站点的各级舒适日数比例和冬季人体舒适度的时空特征及空间分布的主导因素。结果表明:京津冀地区人体舒适度空间分布大致可以分成3种类型,即热舒适平原山地区、冷舒适滨海区和冷不舒适高山区;依据风寒温度,京津冀地区冬季人体舒适度分为冀北、冀南两区,整个地区风寒温度增大趋势显著;京津冀地区人体舒适度与高程、纬度变化均存在显著负相关,其空间分型主导因素为高程、纬度的变化。

关 键 词:京津冀地区  人体舒适度指数  风寒温度  聚类分析

Abstract:Based on the daily temperature,relative humidity and wind speed from 66 weather stations from 1960 to 2005 in Beijing-Tianjin-Hebei region,the temporal-spatial characteristics of human comfort were analyzed using a human comfort index and a wind-chill temperature(WCT)model.The daily human comfort index and WCT of winter were calculated.The division of human comfort index was given by a cluster analysis method.The percentage of comfort day numbers in different grades in typical stations of different divisions,the temporal-spatial characteristics of winter human comfort and its controlling factors were investigated.The results indicate that the spatial distributions of human comfort in Beijing-Tianjin-Hebei region could be divided into three types,i.e.a heat comfort plain upland area,a cold comfort coastal area and a cold uncomfortable mountain area.Winter human comfort could be divided into two types based on WCT,i.e.the northern and southern Hebei province.WCT has an increasing trend in the whole region.Human comfort is a negative correlation with the height and latitude,and the height and latitude are the controlling factors of human comfort spatial distribution.
Keywords:Beijing-Tianjin-Hebei region  Human comfort index  Wind-chill temperature(WCT)  Cluster analysis
