摘 要:为了给大气污染防治预警预报提供参考,利用时间序列模型对大气臭氧浓度进行预测;以2020年1月1日至2020年12月31日期间366个烟台市区大气臭氧日均质量浓度作为研究数据,建立自回归移动平均模型,引入广义自回归条件异方差模型消除时间序列自回归条件异方差效应,最终构建自回归移动平均-广义自回归条件异方差时间序列模型,并对2021年1月烟台市区的大气臭氧日均浓度进行预测。结果表明,所构建的时间序列模型对大气臭氧浓度的短期预测值与实测值基本一致,但随着预测期数的增加,预测值与实测值的相对误差逐渐增大。To provide reference for early warning and forecasting of air pollution prevention and control, atmospheric ozone concentrations were predicted by using time series model. Taking daily average ozone concentrations of 366 Yantai urban areas from January 1, 2020 to December 31, 2020 as research data, autoregressive moving average model was established. Generalized autoregressive conditional heteroskedasticity model was introduced to eliminate autoregressive conditional heteroscedasticity effect of time series. Autoregressive moving average-generalized autoregressive conditional heteroskedasticity model was finally built, which was used to predict daily average concentrations of atmospheric ozone in Yantai urban areas in January, 2021. The results show that the short-term predicted values of atmospheric ozone concentrations by using the built time series model are basically consistent with the measured values, but relative errors between the predicted values and the measured values gradually increase with the increase of prediction period number.
关 键 词:臭氧浓度预测 时间序列模型 自回归移动平均模型 广义自回归条件异方差模型
