摘要
利用实地监测大气TSP浓度和局地气象数据,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子的关系。结果表明,工业区大气TSP月平均浓度0.273mg/m3最高,显著高于交通繁忙区的0.207mg/m3;极显著高于商业区的0.180mg/m3、社区的0.155mg/m3和对照郊区的0.142mg/m3。研究显示,广州市大气TSP污染仍然比较严重。广州市大气TSP浓度与降雨呈现负相关性,与温度呈极显著的负相关性,与相对湿度呈显著的负相关性,与风速呈负相关性,与风向的相关性不明显。各功能区大气TSP浓度与局地气象因子也存在类似的规律。
Based on the monitored total suspended particulate （TSP） levels and the meteorological observation data of air temperature,rainfall,relative humidity,wind speed and wind direction in the period from 2005 to 2006,variations in total suspended particulate （TSP） levels and their relationships with the meteorological factors in the typical functional regions of Guangzhou were studied in this paper.The results showed that monthly mean TSP levels of 0.273 mg/m^3 in industrial regions was higher than 0.207 mg/m^3 in heavily traffic regions,significantly higher than 0.180 mg/m^3 in commercial regions,0.155 mg/m^3 in residential regions and 0.142 mg/m^3 in suburb regions.It is implied that TSP pollution is still a significant problem for environmental protection in Guangzhou City.TSP concentrations were negatively correlated to rainfall,temperature,relative humidity,and wind speed.No significant correlation was found between TSP concentrations and wind direction,due to the fact that wind direction was instable in Guangzhou City.In the different functional regions of Guangzhou,there are similar rules between TSP levels and local meteorological factors.
