摘要
目的 分析昌吉市2018-2022年大气质量,为环境保护、公共健康、城市规划和国际合作等方面提供重要的数据支持和决策依据.方法 收集2018-2022年昌吉市大气污染物数据,分析该地区大气环境状况并采用季节性差分自回归滑动平均模型预测2023年大气主要污染物浓度趋势.结果 2018-2022年昌吉市大气主要污染物均以可吸入颗粒物(par-ticulate matter 10,PM10)和细颗粒物(particulate matter 2.5,PM2.5)为主,其他污染物污染情况不明显.6种常规污染物存在季节性,PM10、PM2.5、二氧化硫(sulfur dioxide,SO2)、二氧化氮(nitrogen dioxide,NO2)、一氧化碳(carbon monoxide,CO)浓度值均在冬季达到最高,臭氧(ozone,O3)则相反,在夏季浓度最高.2022年空气质量指数(air quality index,AQI)值最高,2018年最低,预测数据显示2023年PM10、PM2.5浓度将持续降低.结论 昌吉市空气质量在逐渐好转,预测的数据显示2023年昌吉市PM10、PM2.5浓度相比2022年有所下降,但污染情况在冬季比较明显,需采取持续的防治措施.
Abstract
Objective To analyze the air quality in Changji City from 2018 to 2022,and provide important data support and decision-making basis for environmental protection,public health,urban planning and international cooperation.Methods The data of atmospheric pollutants in Changji City from 2018 to 2022 were collected,the atmospheric environment in the region was analyzed,and the seasonal differential auto-regressive integrated moving average model was used to predict the concentration trend of major atmospheric pollutants in 2023.Results PM10 and PM2.5 were the main air pollutants in Changji City from 2018 to 2022,and the pollution of other pollutants was not obvious.The six conventional pollutants had seasonality,with PM10,PM2.5,SO2,NO2,and CO concentrations reaching their highest in winter,while O3 had the opposite trend,with the highest concentration in summer.The air quality index(AQI)had the highest value in 2022 and the lowest value in 2018,and predicted data showed that PM10 and PM2.5 concentrations would continue to decrease in 2023.Conclusions The air quality in Changji City is gradually improving.The predicted data shows that,compared to 2022,the concentrations of PM10 and PM2.5 in Changji City will decrease in 2023.However,the pollution situation is more pronounced in winter and continuous prevention and control measures need to be taken.
