| 摘 要： | 摘要：对呼和浩特市4种常绿树种的滞尘能力进行了测定，结果表明，树种间滞尘能力有显著差异，常绿乔木中,云杉和杜松是优良的滞尘树种，而油松、圆柏的滞尘能力较弱，并对滞尘机理进行了研究。同一树种离地面150cm、200cm和250cm高度的叶片平均滞尘量依次减少；同一树种西侧和北侧的叶片平均滞尘量明显低于同株树木东侧和南侧的叶片平均滞尘量；同一树种外侧叶片平均滞尘量总是小于里侧的叶片平均滞尘量，最大的相差4倍以上。

| Abstract: | Abstract： Dust removal measurement was taken for 4 tree species in Huhhot. The result show that: Dust catching ability is different from tree species. The ideal plants for dust removal were Picea asperata Mast. and Juniperus rigida of the conifers .However, the dust-retention abilities of Pinus tabulaeformis and Sabina chinensis were relatively poor. Dust catching mechanisms of several evergreen conifers are studied. |
