以紫茎泽兰（EupatoriumadenophorumSpreng）、青蒿（HerbaArtemisiaeAnnuae）、三叶鬼针草（Bidenspilosa）、野牡丹（MelastomaAfffine D．Don）、光叶蕨（Knuiwatsukiacuspidata）为例，分别在河边、路边、山上和污水灌溉的旱地4个采样点采取5种植物的根部和茎叶，测量重金属元素Pb、Cd的含量、富集系数和转移系数并分析数据。结果表明，各种植物不同器官在不同环境中对重金属元素Pb、Cd的富集和转移水平各不相同，就平均水平来说三叶鬼针草对重金属Pb、Cd的富集系数较大，转移系数也高，但其对Pb的转移量明显高于Cd的转移量；紫茎泽兰对重金属元素Cd的富集和转移速度相对高于其它4种植物，说明紫茎泽兰对Cd的吸收和转移比较快，可作为受镉污染土壤进行改良的备选植物种。

This paper takes Eupatorium adenophorum , Herba artemisiae , Bidens pilosa , Melastoma Affine and Knui- watsukia cuspidate as examples. The roots, stems and leaves of these five plant species were collected from four sample plots nearby the river, along the road, on the mountain, in the sewage irrigated dry lands. The contents of the heavy metals like Pb and Cd in these plant organs were measured. Their enrichment coefficient and transfer co- efficient were calculated. The data analysis shows that different organs of various plants performed differently in Pb and Cd enrichment and transfer. Averagely said, Bidens pilosa had a higher enrichment and a higher transfer coeffi- cients. But it transferred more Pb than Cd. Eupatorium adenophorum had a higher speed to enrich and transfer Cd than the other four plants, indicating this plant enriches and transfers Cd faster. Therefore, it can be optionally used to rehabilitate the land polluted by Cd.
