贵阳学院主要绿化植物滞尘能力的研究

Study on the Dust Catching Property of the Campus Plants in Guiyang University

对贵阳学院校园内6种常见绿化植物的滞尘能力进行测定,分析不同位置的植物滞尘能力并进行比较。结果表明,不同植物的滞尘能力差异明显,灌木层中小叶女贞、红花檵木和海桐的滞尘能力最强,单位叶面积的滞尘量最大。在一定时间内,乔木的滞尘量随时间的延长而不断增加、灌木的滞尘量随时间的延长而不断减少。同种植物在不同的功能区滞尘量不同。建议在校园绿化建设中,选择适合本地生长的绿化树种,乔、灌、草合理搭配种植,并且优先考虑滞尘能力强的植物。

Dust retention effect of 6 plant species were tested and analyzed inGuiyang University,the tree dust retention abilities were compared in different functional areas. The results showed than there were obvious differences among the plants tested. Ligustrum quihoui,Loropetalum chinense var. rubrumand Pittosporum tobira was proved the most effective for the dust retention as compared with other arbor species,and laid dust strongly. It was most largest dust retention of per unit leaf area. The dust retention capacity of the arbor increased with time during a certain time,and the shrub decrease. The dust retention effects of the same plant in different areas were different significantly. It suggest that was planted in the construction of campus greening with arbor,shrub,grass of reasonable matching,and elected for growth of loca of greening tree species,and the priority of dust catching property strongly.
