以许昌市东城区为例,对比分析了石楠、大叶黄杨、海桐、小叶黄杨、火棘、小叶女贞6种道路绿化植物的滞尘能力.研究结果表明,石楠的滞尘量最大,为6.42 g/m2,小叶黄杨滞尘量最小,仅1.51 g/m2.就绿化带内、外两侧滞尘量而言,内侧的叶片平均滞尘量明显大于外侧;其中,石楠的内外两侧滞尘量差异最大,内侧滞尘量为5.47 g/m2,外侧滞尘量为4.24 g/m2,两者相差达1.23 g/m2;小叶黄杨的滞尘量差异最小,内侧滞尘量为0.86 g/m2,外侧滞尘量为0.79 g/m2,两者相差仅0.07 g/m2.6种树种滞尘量的空间分布均表现为下部>中部>上部.
以許昌市東城區為例,對比分析瞭石楠、大葉黃楊、海桐、小葉黃楊、火棘、小葉女貞6種道路綠化植物的滯塵能力.研究結果錶明,石楠的滯塵量最大,為6.42 g/m2,小葉黃楊滯塵量最小,僅1.51 g/m2.就綠化帶內、外兩側滯塵量而言,內側的葉片平均滯塵量明顯大于外側;其中,石楠的內外兩側滯塵量差異最大,內側滯塵量為5.47 g/m2,外側滯塵量為4.24 g/m2,兩者相差達1.23 g/m2;小葉黃楊的滯塵量差異最小,內側滯塵量為0.86 g/m2,外側滯塵量為0.79 g/m2,兩者相差僅0.07 g/m2.6種樹種滯塵量的空間分佈均錶現為下部>中部>上部.

Taking Xuchang Eastern District as example,the dust-retention of 6 greenbelts,Photinia serrulata, Buxus megistophylla,Pittosporum tobira,Sabina chinensis,Pyracantha fortuneana,Ligustrum quihoui,was examined. The results show that the highest dust-retention capacity of 6.42 g/m2 was recorded in Photinia serrulata,while the lowest 1.51 g/m2 in Sabina chinensis. As for the difference of the greenbelts inside and outside,the dust-retention capacity of 6 species indicated an order of inside>outside. The most difference of 1.23 g/m2 was recorded in Photinia serrulata,contrasted to the smallest difference of 0.07 g/m2 in Sabina chinensis. Moreover,the spatial distribution of dust-retention suggested an order of lower section>middle section>upper section.
