This study investigates the dust contents retained on the leaves of 13 greening tree species in cement works (polluted site) and shelterbelt (control site) in Aksu. The difference of leave dust-retention was determined by One-way ANOVA (LSD multiple comparisons). Average linkage cluster analysis was then applied to select the species with strong dust and wind resistance. The result shows that these 13 greening tree species can be classified into three categories based on the amount of dust-retention. The first category including Platanus orientalis has the highest dust contents from 5.537 g·m-2 to 7.598 g·m-2 and it can be as a key greening tree species in polluted areas. The second category including Morus alba and Ulmus densa has relatively high dust-retention amount from 3.427 g·m-2 to 5.174 g·m-2 and 4.671 g·m-2 to 6.153 g·m-2 , respectively. The third category has the least dust-retention and includes Salix babylonica, Fraxinus rhynchophylla, Pyrus sinkiangensis, Elaeagnus angustifolia, Vitis vinifera, Malus pumila, Cerasus pseudocerasus, Arminiaca vulgars, Punica granatum. The dust content was ranged from 0.736 to 3.483 g·m-2. The dust-retention contents from the polluted site was obviously higher than that of the control site, differences are significant (p<0.05).
Key words: Aksu; dust-retention contents; greening tree species
