Abstract: Objective To fit the optimal prediction model and explore the temporal distribution characteristics and trend changes of inhalable particles(PM10) pollution in Urumqi City,providing reference for promoting atmospheric governance. Methods Based on the monitoring data of PM10 in Urumqi City from 2016 to 2022,the database of PM10 monthly average concentration was constructed, and the autoregressive integrated moving average model(ARIMA) was used to fit the prediction model of PM10 and analyze its distribution characteristics,and forecast the trend change of PM10 concentration from 2023 to 2024. Results There was a statistically significant difference in the monthly average concentration of PM10 in Urumqi City from 2016 to 2022(P<0.01),and the optimal model was ARIMA(0.0,1)(1,1,0)12. The monthly average concentration values of PM10 in Urumqi City had been decreasing year by year,reaching their maximum values in January,February and December. According to the prediction,the monthly average concentration of particulate matter PM10 in Urumqi City from 2023 to 2024 was consistent with that from 2016 to 2022. Conclusion The optimal model is ARIMA(0,0,1)(1,1,0)12. The monthly average concentration of PM10 in Urumqi City shows a trend of increasing in autumn and winter,and decreasing year by year. This model can effectively predict and analyze the monthly average concentration of PM10 in Urumqi City in the short term.
