【摘要】 本文研究了2005年至2006年广州市不同功能区大气TSP浓度变化及其与气象因予的关系。结果表明,工业区大气TSP月平均浓度(0.273 mg/m~3)最高,显著高于交通繁忙区(0.207 mg/m~3);极显著高于商业区(0.180 mg/m~3)、社区(0.155 mg/m~3)和对照郊区(0.142 mg/m~3)。广州市大气TSP浓度与降雨呈现出显著的负相关性(r=0.685,p<0.05),与温度呈极显著的负相关性(r=0.248,p<0.01),与热岛强度呈显著的负相关性(r=0.176,p<0.05),与相对湿度呈显著的负相关性(r=0.151,p<0.05),与风速的相关性不显著,各功能区大气TSP浓度与气象因子也存在类似的规律。研究表明,广州市大气TSP浓度不仅依赖于大尺度天气背景,而且与本地的气象条件密切相关。更多还原

【Abstract】 Variations of total suspended particulate (TSP) levels and its relationships with the meteorological factors in typical functional regions of Guangzhou during 2005 and 2006 were studied in this paper.The results showed that monthly mean TSP levels of 0.273 mg/m~3 in industrial region is higher than 0.207 mg/m~3 in heavily traffic region,is significantly higher than 0.180 mg/m~3 in commercial region,0.155 mg/m~3 in residential region and 0.142 mg/m~3 in suburb region. Variations of TSP are significantly negatively correlated to rainfall (r=0.685,p<0.05), temperatures (r=0.248,p<0.01),UHI intensity (r=0.176,p<0.05),and relative humidity (r= 0.151,p<0.05),and have no obvious correlation with wind speed in Guangzhou.In different functional regions of Guangzhou,there are some similar rules between TSP levels and the local meteorological factors.TSP levies in atmospheric environment of guangzhou,therefore,are not only depending on the effect of large scale weather background and monsoon circulation,but also on the local meteorological factors such as rainfall,temperature,and humidity.更多还原
