【摘要】 对21种园林植物吸滞环境污染物中硫、铅、镉的能力进行了测定,结果表明:园林植物对环境污染物中硫、铅、镉具有一定的吸收净化能力,并依污染物和植物的不同具有明显差异。对二氧化硫吸收量高的植物有:爬行卫矛、红叶臭椿、马褂木;吸铅量高的植物有:七叶树、紫叶矮樱、红叶臭椿、扶芳藤、北海道黄杨、爬墙虎、五叶地锦、爬行卫矛;吸镉量高的植物有:北海道黄杨、爬墙虎、扶芳藤、红叶臭椿、七叶树、五叶地锦、爬行卫矛。更多还原

【Abstract】 The ability of twenty-one ornamental plants to absorb the sulfur,the lead and the cadmium in the environmental pollutants has been measured in this study.The result showed that,ornamental plants were able to absorb and purify the sulfur,the lead and the cadmium in the environmental pollutants,and the ability differed with the pollutants and the plants varied.The plants that had a large amount of absorption of the sulfur include Euonymus fortunei var.radicans,Ailan thus altissima cv ’Hongye’,Liriodendron chinense;The plants that had a large amount of absorption of the lead include Aesculus chinensis,Prunus ×cistena ’pissardii’,Ailan thus altissima cv ’Hongye’,Euonymus fortunei,Euonymus japonicus,Parthenocissus tricuspidata,Parthenocissus quinquefolia,Euonymus fortunei var.radicans;The plants that had a large amount of absorption of the cadmium include Euonymus japonicus,Parthenocissus tricuspidata,Euonymus fortunei,Ailan thus altissima cv ’Hongye’,Aesculus chinensis,Parthenocissus quinquefolia,Euonymus fortunei var.radicans.更多还原
