| 摘 要： | 对贵阳市西郊一贵州大学蔡家关校区的PM10进行了系统采样，分析了PM10的污染水平及在时间上的污染特征，并探讨了PM10与主要气象因素（如相对湿度、风速、气压、温度等）的关系。结果表明：贵阳市西郊PM10出现轻度污染，且春、夏、秋季PM10超标率分别是24％，25％，14％，超标倍数范围分别是0．04～0．49，0．02～0．35，0．09～0．48；春、夏、秋季的PM10／TSP比值平均值分别为62％，72％，69％，与北京、西安等城市的PM10／TSP比值结果相当，略高于安阳市；春、夏、秋季PM10浓度变化不大，夏季略高、秋季次高，春季略低。春季和秋末白天易出现高浓度污染，而夏季夜间易出现高浓度污染；PM10浓度与相对湿度、风速呈负相关关系，与气压呈正相关关系，与温度的相关性不大。

| Abstract: | The samples of PM10 and TSP were systematically collected by month in Cai Jia-guan Campus of Guizhou University in western urban part of Guiyang City in 2008,and the concentration levels,the characteristics of the spacial variations and the relationships between meteorological factors(such as relative humidity,wind speed,pressure and temperature) of PM10 were analyzed in this article.The results show that there were slightly pollutions by PM10 in western urban of Guiyang City.The rate of PM10 which exceeded... |
