摘　　要：研究32种盆栽于佛山市污染区的城市园林绿化植物对大气二氧化硫(SO2)和氟化物的净化能力及其对大气污染的修复功能。结果显示,竹节树、傅园榕等14种植物对SO2、氟化物等污染气体不但具有较强的抗性,而且具有较高的吸收净化能力,叶片平均含硫量达17442(11754-27658mgkg-1DW),是清洁区(5988mgkg-1DW)的2.9倍;平均含氟量达3725.9(1954.9-5331.7mgkg-1DW),是清洁区(170.3mgkg-1DW)的21倍。表明这些植物对大气SO2、HF复合污染具有很好的净化能力和修复功能,是值得推广的城市园林绿化树种。Seventy-five species of garden plant seedlings were potted under con taminated environment at Dongcun (DC) and Wuxing (WX) near ceramic industry sites in Fosha n City, Guangdong, and at botanical garden (control). The contents of sulphur and fluori ne in the leaves of the thirty-two surviving species were measured after 128 days, among which 14 species including Ficus religiosa, F. microcarpa var. fuyuensis, Lysidice rhodostegia, C arallia brachiata, Ilex rotunda, etc. had great ability to absorb air pollutants SO2 and fluoride. Average sulphur and fluorine contents in leaves of these species pot-grown at contaminated sites wer e 17 442 mg kg-1 DW and 3725.9 mg kg-1 DW, respectively, which were 1.9 times and 20 times higher than t hose at control site, respectively, showing that these species were more tolerant to SO2 and flu oride pollutants.
