泛长三角地区近60年的人体舒适度时空特征分析

Analysis of the Spatial and Temporal Characteristics of Human Comfort in Pan-Yangtze River Delta Region over the Past 60 Years

利用泛长三角地区14个地面气候资料国际交换站1951 ～2010年近60年的气候统计资料,采用温湿指数（THI）作为因子进行分析,对照分级表得出14站近60年的人体舒适度级别,并以每10年为一个时间段进行人体舒适度区的划分和变迁分析,利用sufer软件绘制每10年的THI克里金插值等值线图.结果表明：泛长三角地区近60年来,极为舒适和极不舒适的月份数量都较少,2级、3级、4级舒适度的月份数量较多,舒适度空间分布不均,东南沿海比西北内陆舒适度较高.

The statistical climate data of 14 ground international exchanged stations in the Pan-Yangtze River Delta region over the past 60 years from 1951 to 2010 is used in this study. Using human comfort index, namely temperature humidity index（THI） as a factor to analysis, the human comfort index of 14 stations over the past 60 years has been calculated, and with each 10 years as a time period to analyze the division and change of human comfort index. Then the Kriging contour map of each 10 years THI has been drawn with the software called sufer. The results show that： in the Pan-Yangtze River Delta region over the past 60 years, the number of the maximum comfort months and the minimum comfort months are small, and the number of comfort index level 2, level 3, and level 4 months are bigger. The spatial distribution of comfort index is uneven, and the comfort index in the southeast coast is higher than that in the northwest inland.
