Abstract

From August 2014 to July 2015,taking road monitoring plot in the Tieshanping Forest Park in Chongqing as the contrast,characteristics of atmospheric PM_2.5 and PM₁₀ under the regulation of different tree species,forest stands and structural characteristics were monitored by the High Precision Hand Held PM_2.5 (CW-HAT200).The results showed that variations of atmospheric PM_2.5 and PM₁₀ in the park road and under canopies of seven tree species were larger.Compared with concentrations of atmospheric PM_2.5 and PM₁₀ in the park road,each monitored tree species had different degrees of ability to reduce atmospheric particulate matter,and Liquidambar formosana had a stronger ability to reduce atmospheric particulate matter,but the ability of Phyllostachys heterocycla was weaker.The concentration of atmospheric PM_2.5 and PM₁₀ under the regulation of different forest stands was in the order of conifer-broadleaf forest > broadleaved forest > coniferous forest.The concentrations of atmospheric PM_2.5 and PM₁₀ of different vertical structures from forest stands all were in the order of tree layer > tree and shrub layer > tree,shrub and herb layer.On the contrary,the ability to reduce atmospheric particle matter all was in the order of tree,shrub and herb layer > tree and shrub layer > tree layer.Therefore,forest stand with a complete spatial structure (tree,shrub and herb layer) would have a stronger ability to reduce atmospheric particulate matter.
