	1	Air Pollution Characteristics and Cause Analysis of Main Urban Area of Western Guizhou in the Ghost Festival显示文摘According to the air quality monitoring and meteorological observation data from 2015 to 2020,the air pollution characteristics and causes were analyzed in the Ghost Festival(on the 15 th of the 7 th lunar month)for the main urban area of Liupanshui City in western Guizhou Province.The results showed that air pollution to different extent occurred in the Ghost Festival every year,reaching the level of heavy pollution in half of the year.The pollution time is generally from 21:00 on the day to 01:00 on the next day.The pollutants mainly come from the smoke dust generated by people burning sacrificial offerings and industrial pollution of iron and steel manufacturing under adverse weather conditions.The primary pollutant is PM 2.5,and the annual variation of pollution shows a downward trend.Precipitation weather is in the majority,which is favorable for reducing the pollution degree;the relationship between wind direction,wind speed and pollution degree is closed;the atmospheric inversion is weak,which has no obvious influence on the change of air pollution;the relative humidity is high,which is conducive to the formation and maintenance of pollution;there is a very significant negative correlation between the degree of air pollution and wind energy,and significantly negative correlation between the degree of air pollution and atmospheric turbulence intensity.Advocating civilized sacrifice and strengthening management is beneficial to reducing the degree of pollution.This paper can be used as a reference for air quality forecasts and taking the appropriate measures to reduce pollution.
