摘　　要：为了解“十三五”期间泸州市城市环境空气质量情况,通过对“十三五”期间泸州市环境空气质量监测数据的统计、污染负荷计算和变化趋势分析,结果表明:泸州市SO_(2)、PM_(2.5)和PM_(10)浓度整体呈下降趋势,NO_(2)、CO和O_(3)浓度呈缓慢上升趋势。泸州市环境空气质量呈现出明显的季节差异,颗粒物总体负荷降低,细颗粒物二次贡献增大,大气污染类型以复合型污染为主。上述分析结果对泸州市、川南片区以至成渝地区其他城市进行大气污染治理具有实际指导意义。In order to understand the environmental air quality of Luzhou City during the"13th Five-Year Plan"period,through the"13th Five-Year"period Luzhou environmental air quality monitoring data statistics,pollution load calculation and change trend analysis,the results showed that the concentrations of SO_(2),PM_(2.5)and PM_(10)presented a decreasing trend,while the concentrations of NO_(2),CO and O_(3)presented a slowly increasing trend in Luzhou.The ambient air quality in Luzhou city showed obvious seasonal differences.The overall particle load reduced and the secondary contribution of fine particles increased.Atmospheric pollution type was mainly compound pollution.Above analysis results have practical guiding significance for air pollution control in Luzhou,southern Sichuan region and other cities in Chengdu-Chongqing region.
