几种校园绿化植物滞尘能力研究

目的]为校园绿化植物的选择提供理论依据。方法]试验以山西农业大学校园为试验区,于2007年6~8月对校园内栽种面积最大的2种落叶乔木2、种针叶植物、3种灌木2、种草本、3种藤本,进行滞尘能力的比较研究。结果]针叶植物表现出极强的滞尘能力,其滞尘能力与落叶乔木、灌木、草本、藤本均在0.01水平有差异;滞尘能力由大到小排序为针叶>草本>灌木>藤本>落叶乔木。结论]藤本植物虽然滞尘能力低,但可以阻滞不同高度的灰尘,是很好的垂直绿化植物。

Study on Dust-retention Ability of Different Green Plants on Campus

Objective]The research aimed to provide theoretical basis for the choose of green plant on campus.Method] This study was on the campus of Shanxi Agricultural University from June to August in 2007.Comparative tests of dust-retention ability were carried out between widely planted two deciduous trees,two conifers,three shrubs,two herbs,three lianas.Result]The results showed that the conifers demonstrated strong hysteresis dust ability.And its dust-retention ability had significant differences(P<0.01)compared with deciduous trees,shrubs,herbs,lianas.The order of dust-retention ability was conifers>herbs> shrubs>lianas>deciduous trees.Conclusion] Lianas could absorb dust of different heights and it was very good vertical green plant,even though the dust-retention of it was low.
