济南市常见乔木滞尘能力研究

Dust-retention Ability of Common Arbors in the urban area of Jinan

本研究选择了济南市21种常见乔木,采用差重法进行了滞尘量测定,研究了叶面特性对滞尘能力的影响,并采用综合指数法对其滞尘能力进行了评估。结果表明,不同植物滞尘量差异较大,构树单位叶面积滞尘量最大,达到15.5183g/m2。叶面特性不同,使植物滞尘量存在一定差异,但此影响在统计学上不显著(P>0.05)。构树、白蜡、紫荆、柳树Y值大于0.7,滞尘能力较强。

The study chose 21 common arbors, determining the plant resistance to dust accumulation in 21 common arbors and evaluating the effects of foliage characters and the dust--retention ability. The results showed that differences exist between different plants, and the dust--retention ability of Papermulberry was strongest. Foliar characteristics make plant dust --retention vary, but the effect was not significant in statistics （P 〉 0.05）.
