| 摘 要： | 以2010~2014年重庆市江津区两个环境空气自动监测站逐日空气污染指数(API)、主要污染因子和空气质量级别为基础,分析了近5年该区空气质量变化特征.结果表明,重庆市江津区城市空气质量总体上以优、良天数为主,主要污染因子为可吸入颗粒物.API从时间变化上看,冬季空气质量最差,春秋季次之,夏季最好.气象因子、地理条件以及人类活动对城区空气质量影响显著. |

| Abstract: | Based on the daily air pollution index (API), primary pollutant and air quality level of 2 automatic air monitoring stations in Jiangjin during 2010~2014, the characteristics of air quality were analyzed. The results showed that the urban air quality was excellent and good in the majority, and the primary pollutant was PM10. The API of Jiangjin was worst in winter and best in summer. The air quality was impacted by meteorological factors, geographical conditions and human activities. |
