山西师范大学校园主要绿化植物滞尘能力的研究

本研究对山西师范大学校园23种主要绿化植物的滞尘能力进行了测定,结果表明,不同植物的滞尘能力差异显著,有的可相差2～10倍以上.常绿乔木中,雪松和侧柏是优良的滞尘树种,一周平均滞尘量分别达到17.81g/kg和13.25g/kg;阔叶乔木中,国槐、石榴和碧桃是优良的滞尘树种,一周平均滞尘量分别达到2.23g/m2、2.18 g/m2和1.69g/m2;灌木植物中,小檗和小叶黄杨是优良的滞尘植物,一周平均滞尘量分别达到8.41g/m2和6.85g/m2;草本和藤本植物中,石竹和五叶地锦是优良的滞尘植物,一周平均滞尘量分别达到16.93g/m2和1.39g/m2.不同生活型滞尘能力的顺序为:草本大于灌木大于乔木大于藤本.山西师范大学校园植物的滞尘明显高于哈尔滨、合肥等城市.

Study on the Dust Catching Property of the Campus Plants in Shanxi Normal University

Dust removal properties of 23 plant species were tested and analysed in Shanxi Normal University.The results showed that there were obvious differences among the plants tested.The ideal plants for dust removal were Cedrus deodara(17.81g/kg) and Platycladus orientalis(13.25g/kg) of the conifers,Sorphora japonica(2.23g/m~2),Punica granatum(2.18g/m~2) and Amygdalus persica(1.69 g/m~2)of the deciduous tree species, Berberis thunbergii(8.41 g/m~2)and Buxus sinica(6.85 g/m~2)of the shrubs and Dianthus chinensis(16.93g/m~2) and Parthenocissus quiquefolia(1.39 g/ m~2) of the herbaceous and lianoid species.The dust absorption ability of different life forms was decreased in the order of herb,shrub,tree,liane.The dust catching property of Shanxi normal university was higher than that of Harbin city and Hefei city.
