Analysing the rules of forests for PM2.5 is important given the serious damage caused by air pollution today. Differently sized particle concentrations were measured in the Poplar shelterbelt. The poplar shelterbelt along the Fifth Ring Road near the South Park of the Beijing Olympic Forest Park was selected as a research object, and six monitoring sites were set from the roadside through to the woodland centre. The particle concentrations were monitored from April to December 2013. A handheld DustMate dust monitor (Turnkey Instruments, UK) was used to measure the concentrations. The differently sized particle concentrations were compared inside and outside the forest. The order of the average concentrations of total suspended particulate (TSP) and PM10 were as follows: outside the forest > within the forest > outside the forest. The average concentrations of PM2.5 and PM1 were as follows: outside the forest > outside the forest > within the forest. The concentrations of TSP and PM10 decreased, then increased, and finally declined all the way from the edge on the side of the road to the edge on the side of the park. The trough of the concentration curve was detected near the monitoring site 3F, and the concentrations of TSP and PM10 declined outside the forest on the park side. The concentrations of PM2.5 and PM1 decreased, then increased, and then further decreased. The trough was first recorded around the monitoring site 18F, and the concentration increased outside the forest on the park side.

Abstract


Analysing the rules of forests for PM2.5 is important given the serious damage caused by air pollution today. Differently sized particle concentrations were measured in the Poplar shelterbelt. The poplar shelterbelt along the Fifth Ring Road near the South Park of the Beijing Olympic Forest Park was selected as a research object, and six monitoring sites were set from the roadside through to the woodland centre. The particle concentrations were monitored from April to December 2013. A handheld DustMate dust monitor (Turnkey Instruments, UK) was used to measure the concentrations. The differently sized particle concentrations were compared inside and outside the forest. The order of the average concentrations of total suspended particulate (TSP) and PM10 were as follows: outside the forest > within the forest > outside the forest. The average concentrations of PM2.5 and PM1 were as follows: outside the forest > outside the forest > within the forest. The concentrations of TSP and PM10 decreased, then increased, and finally declined all the way from the edge on the side of the road to the edge on the side of the park. The trough of the concentration curve was detected near the monitoring site 3F, and the concentrations of TSP and PM10 declined outside the forest on the park side. The concentrations of PM2.5 and PM1 decreased, then increased, and then further decreased. The trough was first recorded around the monitoring site 18F, and the concentration increased outside the forest on the park side.
