| Abstract: | Utilizing the monitoring data of inhalation particle matter (PM10) in 2000 at five stations in Beijing, the temporal and spatial variation features of PM10 concentration, the major air pollutant in Beijing, are studied. The analysis also includes the average concentration, the frequencies of different pollution grades, and the hourly variation during the winter heating period and non heating period. The results show that the regional distribution, the annual and daily variation of PM10 pollution are obvious, and the daily changes of PM10 concentration at each station during heating and non heating periods are different. At the same time, the statistical relation between the PM10 concentration and surface meteorological elements is analyzed. |
