| 摘 要： | 通过计算石家庄西北郊大气环境监测站2014年的逐时浓度印痕,系统分析影响当地空气质量的潜在污染来源区域.使用实际气象观测资料和CALMET风场诊断模式获得当地区域边界层风场;使用反向拉格朗日粒子扩散模式计算印痕,分析其平均分布和日变化,以及与主要污染物(PM_(10))浓度变化的关系.结果表明,(1)石家庄地区山地-平原局地环流对风场有重要影响.(2)西北郊站监测结果代表的污染源区域有明显的日变化,午后主要为偏南和东南方向的污染来源,夜间至次日上午主要为西北山前和山地区域的来源.(3)PM_(10)浓度与污染来源区域具有同步的日变化关系,午后浓度下降,夜间浓度升高并维持到次日早上和正午.从夜间至次日上午时段西北方向的污染来源决定了该站的空气质量.(4)监测结果代表的主要污染物来源区域远超出其行政属地范围,外部来源的贡献率超过60%,当地影响不足40%.(5)造成西北郊站监测浓度整体偏高的主要原因是地形和位置因素,及测站以西的实际污染排放源.
