Methods The dust deposition per unit leaf area of each species was quantified by determining the mass difference before and after the treatment of blades. The dust deposition per leaf and plant were further calculated for each species. Based on the dust capturing capacity measured in three different units, cluster analysis on different tree species was carried out from distinct dimensions. Important findings Results showed that the dust capturing capacity differed significantly among tree species, and the ranking changed with measurement units selected in the experiments. For different specific evaluation focuses, choosing a diverse unit combination as clustering factor, the 26 deciduous broad-leaved tree species were broadly divided into different categories representing different dust capturing capacity level. Dust capturing capacity was closely related to the surface characteristics of leaves, the dust capturing method, the plant structure, the leaf amount of whole plant, the dust content of the environment, etc. Therefore, multiple factors should be taken into account in the assessment of dust capturing capacity of different tree species. %U https://www.plant-ecology.com/EN/10.17521/cjpe.2015.0070
