中文摘要：
大叶黄杨强滞尘能力是城市近地面层环境中清除颗粒物污染的重要机制。以大气颗粒物污染严重的石家庄市为代表,选取石家庄裕华路北部市区为研究范围,对大叶黄杨叶片的滞尘效应及滞尘颗粒物粒度特征进行了研究。结果表明,在晴朗或多云微风天气条件下,30个取样点的大叶黄杨叶片平均滞尘量为0.356g/(m2.d),颗粒物的平均粒度值为1.91μm。大叶黄杨叶片滞尘量在石家庄市不同地区的差异排序为:北二环地区>体育大街与东二环地区>中华大街与西二环地区>西郊>东郊>火车站附近地区>博物馆周边地区。因此,石家庄市大气环境治理应针对不同地段的污染情况采取不同的治理方法。
英文摘要：
The leaves of Euonymus Japonicus Thumb can play an important role in adsorbing dust around city streets,especially in northern area in China where broad-leaved trees defoliate in winter.The northern urban area of the Shijiazhuang City polluted seriously by the atmosphere particulates was selected to study the adsorbing dust quantity and dust particle size on the leaves of Euonymus Japonicus Thumb.The results showed that the average quantity of the adsorbing dust was 0.356 g/(m2·d) and the average particle s...
