Abstract: By integrating afforestation project from 2010 to 2012 and precipitation data in Central Shaanxi Plain, the saturated amount of different sizes of atmospheric particles captured by the foliages of main afforestation tree species was investigated using an Aeolian Aerosol Recurrence Analyzer (QRJZFSQ-I). The results showed that the saturated amounts of TSP, PM₁₀, PM_2.5, and PM_1.0 captured by per unit foliage area of main afforestation species were around 4.02-36.46, 1.22-27.70, 0.11-3.71, 0.04-0.83 μg·cm^-2, respectively. In general, the saturated amount of different sizes of particles captured by coniferous species was higher than that by deciduous species. Specifically, the saturated amount of particles captured by cypress was higher than that by pine, while the evergreen broadleaved species captured a higher saturated amount of particles than deciduous broadleaved species. Based on the field data and precipitation data of 14 meteorological stations in Central Shanxi Plain, the saturated amounts of TSP, PM₁₀, PM_2.5, and PM_1.0 captured by the afforestation project from 2010 to 2012 were 455.99×10⁴, 368.70×10⁴, 70.09×10⁴ and 18.59×10⁴ kg·a^-1, respectively.
