摘要
通过对香樟(Cinnamonum campora)、广玉兰(Magnolia grandiflora)、银杏(Ginkgo biloba)、朴树(Celtissinensis)、乌桕(Sapium sebiferum)、桂花(Osmanthus fragrans)、马银花(Rhododendron ovatum)、含笑(Micheliafigo)、杜鹃(Rhododendron spp.)、三角枫(Acer buergerianum)10种亚热带绿化树种对大气中的粉尘、N、S、Cl 4种有害物质的吸收净化能力的初步测定,结果表明:单位面积滞尘量最高的树种是朴树,氮吸收最高的树种是乌桕,硫吸收最高的树种是银杏,氯吸收最高的树种是杜鹃;乔木树种的全氮含量、全硫含量、单位面积滞尘量都比灌木树种的含量高,但是全氯含量比灌木树种的含量低;落叶树种的各净化指标平均值都比常绿树种的高。
Determinations were conducted on air purification capability of ten greening tree species in Hangzhou. The result demonstrated that Celtis sinersis had the strongest capacity of dust retention, Satpium sebiferum had the best effect of absorption of N, and Ginkgo biloba of S, Rhododendron ssp of CI. TN, TS, unit area dust retention of arbor species was larger than that of shrub species, except TCL. The air purification cabilities of deciduous trees were higher than that of evergreen trees.
