摘要:
 为研究灌木滞留颗粒物效应与叶片性状的关系，采用水洗-滤膜法结合比例换算法对福州市19种道路常用绿化灌木在自然和人工模拟饱和状态下单位叶面积的总滞尘、滞留粒径<10 μm（Dp＜10 μm）和粒径<2.5 μm（Dp＜2.5 μm）颗粒的能力进行研究，并分析叶片性状（叶片特征和叶表显微结构）。结果表明，不同树种叶片自然状态滞留颗粒物的量差异显著，黄金榕最大；饱和状态下，各树种滞留颗粒物的量均显著增加，能力排序明显变化，锦绣杜鹃的饱和滞留量最大，福建茶最小。但总体而言，灌木自然和饱和状态滞留颗粒物的能力强弱均与其叶片性状有关。叶表粗糙，具轮生、丛生和簇生叶序及一些色叶植物的滞留能力强；叶缘有缺刻，具狭长形叶的种类易形成湍流，滞留粒径<2.5 μm颗粒的能力强；叶表微结构密被绒毛如锦绣杜鹃，气孔密度大且具有厚蜡质层如黄金榕、琴叶珊瑚等，具网状脉和深沟壑如琴叶珊瑚、花叶假连翘等及有条状凸起或沟壑如朱蕉等种类的滞留能力较强。
Abstract:
 In order to study the relationship between the effects of particles retained by shrubs and leaf traits,washing-membrane filtration combined with proportion conversion methods were adopted to investigated 19 kinds of greening shrubs widely used on roadsides in Fuzhou on their retaining capability to the dust with diameters of Dp<10 μm and Dp<2.5 μm in natural and saturation conditions.Leaf traits,including leaf characteristics and leaf microstructure were analyzed.The results showed that there were significant differences in the amount of particles retained among different shrub species in natural condition,Ficus microcarpa ‘Golden Leaves’ retained the most amount of dust.Compared with natural condition,the amount of particles retained significantly increased and the ability changed obviously in saturation condition,Rhododendron pulchrum was the most and Carmona microphylla was the least.The ability in both natural and saturation conditions were all related to their leaf traits.The shrubs with the leaves of rough leaf surface,rotated phyllotaxis,clumps,clusters,colored leaves demonstrated strong capability to retain dust particles.The leaves with margin and narrow shape which were easy to form turbulence were in favor of particles with the size less than 2.5 μm.Shrubs which leaf surface microstructure were full of fluffy (such as Rhododendron pulchrum),high density stomata and thick epicuticular (such as Ficus microcarpa ‘Golden Leaves’ and Jatropa pandurifolia),net and deep ravines (such as Jatropa pandurifolia and Duranta repens Variegata),stripes or ravines (such as Cordyline fruticosa) were in favor of retaining particles.
