摘要:

利用全国736 个站点1981 ~ 2010 年的逐日气象资料,对人体舒适度指数( ICHB) 时空演变、各影响因子的权重以及夏季6、7、8 月的偏热天数进行了统计分析。研究表明: ( 1) 近30 a 来,我国年均ICHB呈上升趋势,且达到极显著水平,各区的ICHB年际变化与全国的演变趋势总体保持一致; ( 2) 通过对4 季ICHB比较,春、秋、冬3 个季节的ICH上升趋势均比夏季明显,冬季最为明显,春季次之; ( 3) 温度( 湿度和风速) 与ICHB存在着极显著的正( 负) 相关关系,其中温度对ICHB的正影响最大,而湿度和风速对ICHB的负影响主要是通过温度的间接作用来体现; ( 4) 近30 a 来,我国夏季6 月份偏热天数较少,7、8 月份平均偏热天数相当,华南地区偏热天数最多,西北地区最为舒适。

Abstract:

Based on the daily meteorological data from 736 stations in China during 1981 - 2010,the spatio - temporal evolution characteristics of comfort index of human body( ICHB ) were analyzed,at the same time,the weight of every influencing factor and the hotter days from June to August were analyzed statistically. The results are as follows: ( 1) The annual average ICHB in China and each partition presented ascendant trend in the past 30 years,which reached an extremely significant level and the linear increasing trend of ICHB in China is 0. 08 each year; ( 2) The ICHB in spring,autumn and winter presented obvious increasing trend,especially in winter,but the trend wasn’t obvious in summer; ( 3) There were significant positive( negative) correlation between temperature ( humidity and wind speed) and ICHB ,furthermor temperature had the biggest impact on ICHB while the influence of humidity and wind speed on ICHB was mainly indirect effect through temperature; ( 4) Over the past 30 years,the hotter days was more in July and August but less in June, and hotter days were most in Southern China,but the northwest China was the most comfortable one.

Key words: comfort index of human body( ICHB) , path coefficient, spatio - temporal evolution, hotter days
