Study on Dust-Retention Ability of Major Afforestation Tree Species in New Industrial Zone

Abstract:

Dust pollution has become one of the major problems that impact unban environment. While urban vegetation plays an important role in improving the urban atmospheric environment. This study conducted a preliminary research on the dust-retention ability of 20 greening tree species, by field sampling investigating and laboratory analyzing. The 20 greening tree species in Tianjin Airport Economic Area, a new industrial zone of Tianjin, were taken as research object. The results of the study show that: (1) the dust-retention ability of shrubs is bigger than arbors; (2) the dust-retention ability per unit area of different tree species varies; (3) Among Arbors, the order of the dust-retention ability is Populus tomentosa> Sophora japonica> Paulownia tomentosa> Firmiana simplex> Platanus orientalis> Robinia pseudoacacia> Koelreuteria paniculata> Salix matsudana > Fraxinus chinensis; (4) Among shrubs, the order is Syzygium aromaticum> Kerria japonica> Sorbaria sorbifolia> Ligustrum obtusifolium> Malus micromalus> Prunus cistena> Hibiscus syriacus> Prunus cerasifera var. pissardi> Prunus cistena> Lonicera maackii (Rupr.)Maxim.> Sambucus racemosa> Cercis chinensis. The research provides a theoretical basis for choosing the tree species in reducing the atmospheric particulate matter in Tianjin Airport Economic Area and the new industrial zone of northern China. In addition, the greening activity will be in favor of improving the ecological environment of the region.
