摘 要:以2000—2004年山东省中西部五城市(济南、济宁、德州、淄博、泰安)的主要大气污染物SO2、NO2、PM10的浓度资料为依据,分析了2000—2004年五城市主要大气污染物的季节变化特征以及年际变化趋势。根据2004年五城市主要大气污染物SO2、NO2、PM10的日均浓度值,分析了2004年五城市的空气质量现状。结果显示:2004年五城市的空气质量,济南市最差,其次是淄博、德州、济宁,泰安市最好。大气污染物浓度呈明显的季节变化特征,冬季污染最严重,夏季空气质量最好;总体来说,2000—2004年大气污染物SO2、PM10浓度呈逐年下降趋势,NO2浓度没有明显的变化趋势,到2004年,PM10污染浓度依然较高,是最主要的大气污染物。同时分析了引起大气污染物浓度变化的原因,表明大气污染物浓度的变化是地形、污染源和气象条件等因素共同作用的结果。Based on the concentrations of SO2, NO2,PM10 of five cities (Jinan, Jining, Dezhou, Zibo, Taian) in Shandong Province during the period of 2000--2004, the seasonal variation and the annual pollution changing trend during 2000--2004 have been analyzed. Based on the daily average concentrations of SO2, NO2, PM10 of five cities in 2004, the air quality in 2004 was analyzed. Results show that the air quality of 2004 in Jinan is the most serious, then it is Zibo, Dezhou, Jining and Taian in the order; the pollutant concentrations showed significant seasonal variations, and the air qualities were best in summer and worst in winter. In general, the concentrations of SO2 and PM10was decreasing during 2000--2004, but the concentrations of PM10 is still in a high level in 2004. However, the variation of NO2 was not obvious. Furthermore, the quality were also analyzed, the cooperation of the terrain, pollution the very important. possibl source e causal factors of the changing of air and meteorological condition should be the very important.
