摘要
分析了南昌市2013—2016年大气污染物浓度的时空变化特征。结果表明:2013—2016年南昌市环境空气质量逐年好转;污染物浓度有明显的季节性变化特征;O_3为首要污染物的天数逐年上升,PM_(2.5)和O_3复合污染明显;颗粒物污染状况较重,但呈逐年好转趋势,并正逐步由固定污染源污染为主向移动源污染为主转变;污染物浓度具有区域分布特征,城市近郊、远郊受固定污染源的影响较大,市区交通密集区域受移动源影响较大。
The temporal and spatial characteristics of major air pollutants concentration during2013—2016 in Nanchang were analyzed. The results showed that： the ambient air quality of Nanchang was improved year by year during 2013—2016; the pollutants concentration obviously changed seasonally; the number of days that O3 was the primary pollutant rose year by year, compound pollution of PM（2.5） and O3 was obvious; the pollution status of particulate was heavier, but it tended to improve, and Nanchang was shifting from fixed sources to mobile sources; pollutants concentration had regional distribution characteristics, urban suburbs and suburbs were more affected by fixed sources of pollution, urban traffic-intensive areas were more affected by moving sources.
