【摘要】 在调研的基础上,收集5种常见绿化树种叶片在不同城市滞尘数据及6种树种叶片吸滞重金属的数据,探讨常见树种叶片滞尘及吸滞重金属的能力.结果表明:大叶黄杨滞尘能力高于银杏、垂柳、紫叶李和香樟,但紫叶李滞尘潜能最大.树种叶片每周滞尘能力比例,雨后第一周滞尘量占树种叶片总滞尘量比例较大.对Pb、Cd、Cu、Zn吸滞量最大的树种依次为银杏、臭椿、国槐和紫叶李,对Pb、Cd、Cu、Zn具有最大吸滞潜能的树种依次为国槐、圆柏、国槐、国槐.更多还原

【Abstract】 On the basis of literature investigation,the dust retention data of the leaves of five common greening tree species in different cities and the stagnation of heavy metals data of the leaves of six species were collected,and the ability of the dust retention and stagnation of heavy metals of the leaves of common tree species is discussed. The results show: Buxus megistophylla has higher dust retention ability than Ginkgo biloba,Salix babylonica,Prunus cerasifera and Cinnamomum camphora,but Prunus cerasifera has the largest dust retention potential. Among the proportion of the leaves weekly dust retention ability of tree species,the amount of dust retention in the first week accounted for a large proportion of the total dust retention of tree species.The species with the largest stagnation of Pb,Cd,Cu and Zn were Ginkgo biloba,Ailanthus altissima,Sophora japonica and Prunus cerasifera. The species with the largest stagnation potential for Pb,Cd,Cu and Zn were Sophora japonica,Sabina chinensis,Sophora japonica and Sophora japonica.更多还原
