| 摘 要： | A study of soils and four flourish plants in the heavy metal polluted area by lead/zinc mine in northwestem Guizhou Province. In this study four plants were collected, the species were： Sambucus Chinensis Linn, lxeris gracilis （DC.） stebb, Buddlej daxidii Franch.ex.sinarum lmp. and Senecio scandens. The fractions of heavy metals in the soil were distinguished by the short sequential extraction procedure （I. Maiz, 1997）, the available fractions and residual fractions of heavy metals in the soil could be separated. The plant digestion was effected by means of the microwave digest system （Durali Mendil, 2004）. In each step Pb, Zn and Cd were analyzed by FAAS. This study analyzed the heavy metals （Pb, Zn, Cd） contents of the soil and plant. It is found that the contents in the plant increased linearly with heavy metal concentrations in soil. The concentrations of Pb, Zn, Cd in the four plants follow the order of Zn〉Pb〉Cd. Sambucus Chinensis Linn and lxeris gracilis （DC.） stebb were proved to have good metal-enrichment and transport ability for heavy metals in the soil.
