通过选择6种具有代表性的道路常绿植物，应用接触角测定仪测定了不同树种叶片的接触角，通过扫描电镜观察比较了6种常绿植物的叶表面形态结构，分析其对滞尘能力的影响。试验结果表明常绿植物叶片正面接触角越大，滞尘能力越小；表面叶孔越多，粗糙度越大，滞尘能力越强。研究成果可为城市绿化树种的选择提供基础依据。
通過選擇6種具有代錶性的道路常綠植物，應用接觸角測定儀測定瞭不同樹種葉片的接觸角，通過掃描電鏡觀察比較瞭6種常綠植物的葉錶麵形態結構，分析其對滯塵能力的影響。試驗結果錶明常綠植物葉片正麵接觸角越大，滯塵能力越小；錶麵葉孔越多，粗糙度越大，滯塵能力越彊。研究成果可為城市綠化樹種的選擇提供基礎依據。

Six highway evergreen plants were selected to investigate the effects of leaf surface characteristics on dust-retaining capability. Contact angle of water droplet on leaf surface was measured by goniometer and scanning electron microscopy was used to compare their surface morphology. Results showed that dust-retaining capabilities increased with the decrease of contact angle of the leaf surface. It also indicated that higher stomata density and roughness would result in higher dust-retaining capabilities. The result will provide scientific data for choosing evergreen tree species for urban greening.
