【摘要】：基于AQI数据,从空气质量状况、日历效应、首要污染物特征等视角对滇中、黔中和北部湾城市群空气污染统计规律进行了比较分析,重点挖掘了城市群间空气污染的差异性,并对差异原因进行了深层分析。三城市群间空气污染统计规律的差异性主要表现在:(1)虽与全国平均相比,滇中、黔中和北部湾城市群空气污染程度相对较轻,但三城市群间空气污染状况呈现明显的差异性,滇中城市群空气质量最好,黔中城市群空气质量最差,北部湾城市群居中;(2)滇中、黔中和北部湾城市群空气污染存在明显的"节日效应"及"季节效应",且季节效应异质性明显;(3)三城市群出现频率最高的首要污染物的种类明显不同,其中黔中城市群首要污染物为PM2.5的天数占比高达50%左右,与《大气污染防治行动实施情况考核办法》存异,该办法需进一步细化和完善。
[Abstract]:Based on the data from AQI, the air quality status, calendar effect, the primary pollutant characteristics and so on Yunnan, Guizhou and North Bay city group of air pollution statistics are analyzed, and focuses on the differences between the air pollution of the city group, and the reason for the difference of the deep analysis. The difference between the three groups of city air pollution statistical law is mainly manifested in: (1) although compared with the national average, Yunnan, Guizhou and North Bay city group of air pollution is relatively light, but the air pollution situation of three city groups showed significant differences, Yunnan city group the best air quality, air quality in the city of Guizhou group is the worst. The North Bay City Group Center; (2) in Yunnan, Guizhou and North Bay city group of air pollution has obvious "holiday effect" and "seasonal effect", and the seasonal effect obvious heterogeneity; (3) the three city group appeared the highest frequency of primary pollutant The species is obviously different, which in Guizhou city group the primary pollutant PM2.5 days accounted for up to about 50%, and "the air pollution prevention action to implement different measures for assessment of the way >, need to be further refined and improved.
