| 摘 要： | 利用2006-2010年上海市青浦区PM10和同期地面气象要素的监测资料,定量分析PM10的季节变化规律以及PM10与降雨量、大气湿度和风速之间的关系。分析结果表明:PM10浓度在夏季处于低值,冬季处于高值;5mm/d以上的降雨对PM10有显著的清除作用,且春夏季降雨的清除作用大于秋冬季节。PM10浓度与大气湿度基本呈负相关关系。风速在一定范围内有利于PM10的扩散但不至造成扬尘,春夏季节的适宜风速是1.5～3.5m/s,冬季的适宜风速是1.5～2.5m/s。

| Abstract: | Based on the monitored data of PM10 and surface meteorological elements, the thesis analyzes the seasonal variety of PM10 mass concentration and its relationship between rainfall, air humidity and wind speed in fixed quantity in Qingpu district of Shanghai city. The results show that: The PM10 mass concentration is lower in summer and higher in winter; Rainfall which is more than 5 millimetre per day has marked effects on eliminationg the pollution of PM10. And the effect is better in spring and summer. There is a negative correlation betteen PM10 mass concentration and air humidity. Wind speed in certain range is helpful for pollutant diffusing but will not raise the dust. The appropriate wind speed is 1.5～3.5 m/s in spring and summer, and 1.5～2.5 m/s in winter. |
