摘要
以空气质量指数(AQI)为研究对象,对宁夏回族自治区吴忠市、固原市、石嘴山市、中卫市及银川市空气质量进行分析,结果表明:空气良好率最好的是固原,其后依次为中卫、吴忠、银川、石嘴山;从季节分布来看,污染集中在冬季,12月、1月污染物达到最高值;2015~2017年严重污染时后向轨迹主要来源于西北地区,其次是西南地区。
Taking the air quality index (AQI) as the research object, the air quality of Wuzhong City, Guyuan City, Shizuishan City, Zhongwei City and Yinchuan City in Ningxia Hui Autonomous Region was an-alyzed. The results showed that Guyuan had the best air quality rate, followed by Zhongwei City, Wuzhong City, Yinchuan City and Shizuishan City. According to the seasonal distribution, the pol-lution was concentrated in winter and reached the highest value in December and January in 2015~2017;the backward trajectory of serious pollution mainly came from the northwest, followed by the southwest.
