“十三五”期间宁夏环境空气质量变化特征

Characteristics of Ambient Air Quality Changes in Ningxia During the "13th Five-Year Plan" Period

依据2016—2020年《宁夏回族自治区生态环境质量报告书》中的环境空气质量监测结果,以优良天数比例变化情况及可吸入颗粒物(PM_(10))、细颗粒物(PM_(2.5))、二氧化硫(SO_(2))、一氧化碳(CO)、臭氧(O_(3))、二氧化氮(NO_(2))六项主要空气污染物浓度值,分析全区银川市、石嘴山市、吴忠市、固原市、中卫市环境空气质量变化趋势,得到环境空气质量变化特征。为“十四五”期间的蓝天保卫战提供参考。

Based on the ambient air quality monitoring results in the"Ningxia Hui Autonomous Region Ecological Environment Quality Report"during 2016-2020,ambient air quality trend was analyzed with six main pollutant concentration values including the changes of good days ratio,particulate matter(PM_(10)),fine particulate matter(PM_(2.5)),sulfur dioxide(SO_(2)),carbon monoxide(CO),ozone(O_(3))and nitrogen dioxide(NO_(2))in local cities of Yinchuan,Shizuishan,Wuzhong,Guyuan and Zhongwei to obtain the ambient air quality change characteristics to serve the blue sky protection campaign during the"14th Five-Year Plan"period as reference.
