| 摘 要： | 本文利用贵阳市8区县国家级地面观测站1987-2016年的逐日地面观测资料,运用统计分析、相关分析、通径分析等方法来分析了贵阳地区的气温、相对湿度、风速等气象要素的气候特征,并对人体舒适度指数的时空分布特征进行了分析,探讨了各气象要素与人体舒适度指数之间的相关关系。结果表明：(1)贵阳地区的气温分布存在南北差异,南部最高,中部次之,北部最低；贵阳各地每月的平均相对湿度都很大,均在75%以上；月平均风速在1.5-2.5m/s之间,空间分布差异不大。(2)4月到10月,来贵阳各地旅游都较为舒适,尤其是在夏季(6-9月),最为舒适。从空间分布来看,人体舒适度指数分布为南部＞中部＞北部。(3)人体舒适度指数和气温为明显的正相关关系,与相对湿度、风速为负相关关系。其中气温对人体舒适度指数的影响最为显著。

| Abstract: | Based on the surface observation data of 8 stations in Guiyang from 1987 to 2016, the article analyzed the climatic characteristics of meteorological factors such as temperature, relative humidity and wind speed in Guiyang by using statistical analysis, correlation analysis and path analysis.The patial and temporal distribution of comfort index of human characteristics were analyzed, and discussed the relationship between the various meteorological elements and comfort index of human. The results show that: (1) There is a north-south difference in temperature distribution in Guiyang, with the highest in the south, the second in the middle and the lowest in the north; the average monthly relative humidity in Guiyang is over 75%, and the average monthly wind speed is between 1.5 and 2.5 meter per second, little difference in spatial distribution. (2) From April to October, it is more comfortable to travel around Guiyang, especially in summer (from June to September). The spatial distribution of comfort index of human in a descending as southern,central and northern. (3) There is a obviously positive correlation between comfort index of human and temperature, and there is a negative correlation between relative humidity and wind speed. Among them, temperature has the greatest impact on comfort index of human. |
