摘要:比较了吉林市6种绿篱植物在不同季节和不同时间的滞尘能力。结果表明,树种不同,单位叶面积滞尘量有差异,金山绣线菊和金焰绣线菊滞尘能力较强,同种植物的滞尘能力为夏季>春季;在达到饱和之前,随着时间的延长,单位叶面积滞尘量增加,雨后第10天滞尘量对总滞尘量的贡献最大,雨后14 d达到饱和。

Abstract: The dust retention capacities of 6 hedge plants in different seasons and times in Jilin city were compared. The results showed the dust reduced quantity in different greening tree species with much differences. Spiraea bumalda cv. Gold Mound and Spiraea bumalda cv. Gold Flame had the strongest dust-blocking effect. The dust detaining abilities in different seasons of the same tree species was Summer>Spring. The amount of dust retention of the six tree species increased with time before the foliar dust amount reached the maximum.The contribution of the dust reduce quantity to total dust reduce quantity was the best at the 10th day after raining. It reached the maximum at the

14th day after raining.

Key words: hedge plants; dust retention capacity;Jilin city

近年来随着工业的快速发展,城市空气中粉尘含量远超过世界卫生组织规定的标准[1],

灰霾天气的频频出现,大雾橙色预警的持续拉响,让人们对空气质量的关注程度逐步加大。园林植物由于其叶片分泌黏性的油脂和汁液等使其具有较强的滞尘能力,是公认的户外除尘的有效途径[2]。研究者针对不同城市、不同功能区、不同树种以及同一树种不同时间段滞尘效果

进行了大量的研究[3]。研究选择6种绿篱植物滞尘能力季节性的变迁、累积滞尘量随时间迁移的变化趋势以及最大滞尘量进行多方面分析,以期为吉林市绿篱植物的选择和配置提供一定的参考。
