Abstract: The particlecapturing capacities of common greening tree species in typical garden areas in Beijing were measured in autumn by aerosol regenerator (QRJZFSQ-I), and the adsorption amount of particulate matter per hectare of woodland was calculated. The results showed that the coniferous species had stronger ability of absorbing particles (PM₁₀, PM_2.5 and PM_1.0) than broadleaf species. The abilities to adsorb different sized particles were not significantly different among coniferous species, but were significantly different among broadleaf trees at Nanhaizi Park, in which Populus spp. (1.256 kg·hm^-2·a^-1) and Salix babylonica (1.153 kg·hm^-2·a^-1) had the strongest adsorption capacity for PM₁₀, and Fraxinus chinensis had the strongest adsorption capacity for PM2.5 (0.367 kg·hm^-2·a^-1) and PM_1.0 (0.107 kg·hm^-2·a^-1). The same species at different sites showed the same adsorption capacity for total suspended particulates (TSP) and PM₁₀, but not for PM_2.5 and PM_1.0. The maximum adsorption (11.043 kg·hm^-2·a^-1) of S. chinensis for PM_2.5 and PM_1.0 was observed at Nanhaizi Park, which was 15 times as much as that at Beijing Botanic Garden. PM₁₀ accounted for a high percentage of the adsorbed particles, and gradually declined along the urbansuburbouter suburban gradient.
