摘　　要：选取1967—2016年武汉市气象观测站点逐日气象数据,通过通径分析法和线性趋势法评价并分析了武汉市人体舒适度指数(CIHB)近50年年际变化特征以及温度、风速和湿度三个影响因子之间的权重关系、夏季(6、7、8月)暑热天数动态变化。结果表明:(1)武汉市近50年年均CIHB呈明显的波动上升态势,线性趋势指数达0. 079/年比较不同季节武汉市CIHB变化特征,除夏季外,其余三个季节均表现出明显的上升态势,其中又以春季最为明显,秋冬两季次之;(3)温度、风速和湿度与CIHB之间有着十分显著的相关性,其中以温度对CIHB值的正影响最为明显,而风速和湿度负影响则是通过温度这一指标间接地作用于CIHB;(4)近50年来,武汉市夏季(6、7、8月)暑热天数均在15天以上,整体呈现出先上升后下降再上升的变化态势,7月为武汉市夏季最不舒适的月份,6月份则相对更舒适。This paper selects daily meteorological data of meteorological observation stations in Wuhan from 1967 to 2016,Through the path analysis method and the linear trend method,we has evaluated and analyzed the interannual variation characteristics of the Wuhan City comfort index of human body（CIHB）over the past 50 years and the weight relations among the three influencing factors of temperature,wind speed and humidity,and the changes of heater days in summer（June,July,August）.The results showed that：（1）The annual average CIHB of Wuhan in the past 50 years showed a clear upward trend of fluctuation with a linear trend index of 0.079/year;（2）Comparing the characteristics of CIHB in Wuhan in different seasons,except for summer,the other three seasons showed a clear upward trend,of which the most obvious was in spring and the second in autumn and winter.（3）There is a significant correlation between temperature,wind speed and humidity and CIHB,of which the positive effect of temperature on CIHB is the most obvious,while the negative effect of wind speed and humidity is indirectly on CIHB through the indicator of temperature;（4）In the past 50 years,the number of heater days in Wuhan in summer（June,July and August）all exceeded 15 days,showing a trend of first increasing,then decreasing and then rising.July was the most uncomfortable in Wuhan in summer month,June is relatively more comfortable.
