| 摘 要： | 东北已成为我国又一个霾污染多发和重发区域.采用2013～2017年东北区域大气污染物地面监测数据、卫星数据和气象数据等信息,探讨了中国东北地区空气质量时空分布特征与重度污染成因.结果表明,"沈阳-长春-哈尔滨"带状城市群是全年污染最严重的区域,空气质量指数(AQI)的空间分布具有明显的季节性,冬季污染最严重,春季吉林省西部周围为椭圆形污染区,夏季和秋季大部分时间空气质量最佳.3个典型的霾污染时期是10月下旬和11月上旬(即秋末和初冬,时期一),12月下旬和1月(即冬季最冷的时候,时期二),及4月到5月中旬(即春季沙尘和农业耕作期).时期一,季节性作物残茬焚烧和冬季采暖用煤燃烧产生的PM_(2.5)强排放是极端霾事件发生的主要原因(AQI 300);时期二,在最严寒月份里,重度霾污染事件(200 AQI 300),主要由燃煤和汽车燃料消耗的PM_(2.5)排放量高,大气边界层较低,以及大气扩散性差等共同引起;时期三,春季PM_(10)浓度较高,主要是由内蒙古中部退化草原的风沙和吉林省西部裸地的区域性扬尘传输造成的.同时,当地农业耕作本身也释放PM_(10),并提升了裸土的人为源矿物尘的排放强度.
