Dusts captured by the leaves of 15 urban landscape plants were measured in this study using corresponding indices and assessment methods.Models were set up to evaluate the ecological effects of major landscape plants on the air purification.In addition,factors influencing the capacity of dust capture on the surface of the landscape plants were analyzed to provide some scientific information to improve the ecological environmental quality.Results indicated that there were obviously differences on dust removal in different sampling sites.Trees can capture the largest amount of dust,indicating that the trees were the principle plants that adsorbed dust.The ability of capture dust was closely related to leaf surface characteristics such as crease,coarseness,floss,grease and leaves' wetness.The amount of dust captured was depending on the total area of leaves,angle of branches and shapes of tree crown etc.
