| 摘 要： | 采用比浊法消解和定容、721型分光光度计测定重庆市主城区3个污染级区域不同种类植物叶片的含硫量,以计算主要绿化树种叶片的吸硫能力,结果表明:落叶阔叶树种叶片的含硫量>常绿阔叶树种>针叶树种;乔木叶片的吸硫能力>灌木吸硫能力。在研究的11种绿化植物中,日本珊瑚(Viburnum awabuki)和广玉兰(Mag-nolia grandflora)吸硫能力较强。

| Abstract: | The sulphur content of leaf blades of various plant species in 3 polluted zones of central downtown of Chongqing city is determined by turbidimetry,constant volume and 721-typed spectrophotometer to calculate sulphur absorbable ability.The result indicates that sulphur content is ordered from large to small as deciduous plants >evergreen plants> coniferous plants;sulphur absorbable ability of arbor is larger than that of shrub.Among 11 green plants studied,the sulphur absorbable ability of Viburnum awabuki and Magnolia grandflora is comparative stronger. |
