| 摘 要： | 人居舒适度是一种反映气象条件对人体感受影响的指数。本文应用北京地区1974-2004年气象数据计算得出人居舒适度,分析其变化规律及趋势,得出结论:近三十年北京地区的月平均温度有明显的上升趋势,夏季闷热日天数有一定的减少,但是酷热日天数却明显增加,人居舒适度等级为热的天数逐年增加。文中所选择的由城区到郊区分布的四个气象站之间人居舒适度的变化存在差异,一定程度上反映了城市化对城市小气候的影响。

| Abstract: | Habitat comfort index is a reflection of the weather conditions on human feelings.In this paper,the changes of habitat comfort were calculated and analyzed month by month based on the meteorological data from 1974 to 2004.Results showed that the average temperatures of January and July showed a obvious upward trend.The number of muggy days was decreasing while the number of broiling days was increasing on hot summer days.The hot grade of habitat comfort index appeared more frequently.Moreover,the difference... |
