Roem，楝树和Woodfordia floribunda (L.)。选取大小均匀、龄期均匀、分布均匀和公路两侧常见的库尔兹进行研究。在一年的三个主要季节(雨季、冬季和夏季)对选定的植物叶片上的积尘量进行了估算。样本采集于距离道路两侧两个水平距离(0-5 m和5-10 m)。结果表明:叶蝉叶片积尘量从0.0083 g m-2到0.0597 g m-2，积尘量从大到小依次为:叶蝉>，花叶>，苦参>，叶蝉>。 Season wisethe examined plant species followed the descending order winter > summer > rainy season. Plants grown at a distance of 0-5 m accumulated higher dust on their leaves as compared to 5-10 m distance from the road. Due to surface characteristics of twigs, bark and foliage of the plants particulate matters are captured by them and remain there for extended time period. From the results of this study, it could be inferred that the air quality in urban/ arid areas can be improved by planting firstly the species G. optiva and W. floribunda along road sides of similar highways to national highway-22. }, number = {36}, doi = {10.12944/CWE.11.1.10} }
