[Objective] Dust catching property was a factor which should be considered in the choice of the green tree species when the environmental pollution of the city was becoming serious.[Method] Dust catching properties of ten plant species were studied and analyzed in Northern China.[Result] There were obvious differences among the plants tested.Magnolia denudate,Sophora japonica,Contoneaster multiflorus,Lonicera maackii and Berberis thunbergii var.atropurpurea were proved effectively in dust catching whereas Populus tomentosa,Fraxinus chinensis,Forsythia suspense and Ligustrum lucidum were not adaptive.[Conclusion] Magnolia denudate,Sophora japonica,Contoneaster multiflorus,Lonicera maackii and Berberis thunbergii var.atropurpurea should be given prior consideration in the choice of the green tree species in Northern China.
