摘　　要：采用人工模拟熏气法,研究了36种广州市园林绿化植物对SO2和NO2气体吸收净化能力,以系统聚类分析方法为依据,将参试植物的吸收净化能力划分为强性、较强、中等、较弱及弱5个等级。结果显示,在不同SO2质量浓度(0.259和0.448 mg.m-3)环境下,黄槐、鸡冠刺桐、红花银桦、木棉、红千层、大花紫薇、复羽叶栾树吸收SO2能力具有强或较强的能力,而罗汉松、竹柏、深山含笑、乐昌含笑、观光木、樟树、阴香、双翼豆、印度紫檀、大花五桠果、长芒杜英、五月茶、海南蒲桃、芒果、海南红豆、糖胶树和幌伞枫吸收SO2能力表现为较弱或弱;在NO2质量浓度(0.149和0.428 mg.m-3)环境下,黄槐、黄葛榕、红花银桦、红千层、麻楝、复羽叶栾树、大花紫薇和小叶榄仁吸收净化NO2能力为较强或强,而深山含笑、五月茶、芒果、海南红豆、糖胶树和桂花叶片对NO2吸收能力表现为较弱或弱。在不同SO2和NO2浓度环境下,黄槐、红花银桦、红千层、复羽叶栾树和大花紫薇叶片对SO2和NO2吸收净化能力表现为强或较强,而深山含笑、五月茶、芒果、海南红豆、糖胶树叶片对SO2和NO2吸收净化能力为较弱或弱。研究结果为珠三角城市功能型园林植物选择和广东生态景观林带建设提供科学依据。To compare the ability of landscaping plants to decontaminate toxic gases,We studied the decontamination ability of Sulfur dioxide and Nitrogen dioxide of 38 young landscaping plants,which widely used in landscaping in Guangzhou city with artificial simulated fumigation method.According to the results of system cluster analysis by SPSS software,resistances and absorbencies of the participants can be graded five levels： strong,moderately strong,mid-level,moderately weak,and weak.Results showed that the decontamination ability of Sulfur dioxide for Cassia surattensisBurm,Erythrina crista-galli,Grevilleabanksii,Gossampinusmalabarica,Callistemon rigidus,Lagerstroemia speciosa,Koelreuteriabipinnata was strong capacity,while Podocarpusmacrophyllus,Podocarpusnagi,Micheliamaudiae,Micheliachapensis,Tsoongiodendronodorum,Cinnamomumcamphora,Cinnamomumburmannii,Peltophorumtonkinense,Pterocarpusindicus,Dillenia turbinate,Elaeocarpusapiculatus,Antidesmabunius,Syzygiumhainanense,Mangiferaindica,Ormosiapinnata,Alstoniascholaris,Osmanthusfragrans was weak levelin Environment of the different concentration of SO2（0.259 and 0.448 mg.m-3）.The decontamination ability of Nitrogen dioxide forCassia surattensisBurm,Ficusvirens var.virens,Grevilleabanksii,Callistemon rigidus,Chukrasiatabularis,Koelreuteriabipinnata,Lagerstroemia speciosa,Terminaliamantaly was strong capacity,while Micheliamaudiae,Antidesmabunius,Mangiferaindica,Ormosiapinnata,Alstoniascholaris,Osmanthusfragrans was weak level in Environment of the different concentration of NO2（0.149 and 0.428 mg.m-3）.The decontamination ability of Sulfur dioxide and Nitrogen dioxide for Cassia surattensisBurm,Grevilleabanksii,Callistemon rigidus,Koelreuteriabipinnata,Lagerstroemia speciosawas strong capacity,while Micheliamaudiae,Antidesmabunius,Mangiferaindica,Ormosiapinnata,Alstoniascholaris was weak level in Environment of the different concentration of SO2 and NO2.These studies may be provide a scientific basis for functional garden plant selection in the Pearl River Delta
