以海南热带海洋学院(三亚校区)校园行道树优势树种高山榕、大叶相思、印度胶树、菩提树、非洲楝、火焰木、马占相思、香樟、鸭脚木、小叶榄仁、垂叶榕、隆缘桉为研究对象,比较了乔木绿化树种的降温增湿和滞尘能力。结果表明:在相同环境生长的种龄相当的树种,降温增湿效应不同,高山榕、大叶相思、印度胶树的降温增湿能力最好;降温增湿效应比较差的是隆缘桉、小叶榄仁和垂叶榕。不同树种的滞尘能力也有差异,其中滞尘能力较强的乔木树种是火焰木、菩提树、高山榕和印度胶树。该研究结果对校园绿化和城市行道树的规划选择都具有一定的参考价值。 To Hainan Tropical Marine College (Sanya Campus) campus tree trees dominant tree species alpine Ficus, Greater Acacia, Indian gum tree, linden, African melia, flame wood, Acacia mangium, camphor, duck feet wood, , Long Yuan eucalyptus as the research object, compared the trees green tree species to cool and humid and dust retention capacity. The results showed that the cool-humidifying effect was different between trees of the same age and in the same environment. The alpine fig, Lobular leaves and leaves Ficus. Dust retention capacity of different species is also different, among which the tree species with stronger ability of dedusting are Flamewood, Linden, Alpine Ficus and Indian gum. The results of this study have certain reference value for the planning of campus greening and urban roadside tree.
