景洪市环境空气质量状况及污染特征分析

Analysis of Air Quality and Pollution Characteristics of Jinghong City

利用2015—2017年景洪市国控空气自动监测点的环境空气质量监测数据,分析了景洪市环境空气质量现状、变化趋势以及污染特征。结果表明:景洪市环境空气质量总体较好,污染主要出现时段为每年的春季(2—5月),以细颗粒物和臭氧为主的复合型污染态势初显;颗粒物与SO_2、NO_2日均值均呈正相关,SO_2与NO_2日均浓度呈正相关。此外,根据对景洪市周边环境的分析,针对环境空气质量现状,提出了相关对策建议。

In order to examine the current situation of air quality and explore the characteristics of atmospheric pollution in Jinghong city,the monitoring data of air environmental quality of two national air automatic monitoring stations（ Jinghong Jinangbei,Jinghong Jiangnan） from 2015 to 2017 were adopted. The present situation of air environmental quality,trends,and pollution characteristics were analyzed. The results showed that the air quality was generally good,and the pollution mainly occured in the spring（ February to May） of each year,and the complex pollution situation with fine particulate matter and ozone was first appeared. Particulate matter was positively correlated with the mean of SO2 and NO2,and the average daily concentration of SO2 and NO2 was positively correlated. In addition,based on the analysis of the surrounding environment of Jinghong city,relevant countermeasures and suggestions were put forward.
