摘　　要：研究了高山榕(F.altissima)、细叶榕(F.microcarpa)等8个树种对陶瓷工业污染土壤的修复能力。结果表明,8个树种对4种污染元素(S、Zn、Cu、Pb)的相对积累能力大小与单株干物质量的次序较为一致,单株干物质量可以解释89.8%、86.2%、88.8%、20.5%的S、Zn、Cu、Pb单株积累量变化,叶片和枝条的Pb含量分别可以解释67.3%和59.9%的Pb单株积累量变化。其中,银柴具有突出的S富集能力,很大程度上弥补了其生物量不足的缺陷;翻白叶树的S、Cu、Pb的富集系数一般,但转移系数大大高出其他树种。研究发现,不同树种对污染元素的吸附量、单株积累量以及富集系数和转移系数差异很大,这对筛选生物量大且富集污染物能力强的高效污染修复树种来说具有重要意义。The restoration of several afforest trees to the contaminated soil by ceramics industry were investigated. The results showed that total dry mass per plant could explain 89.8%, 86.2%, 88.8% and 20.5% of the S, Zn, Cu and Pb accumulation capacity per plant respectively while leaf Pb content and branch Pb content could explain 67. 30% and 59. 9% of Pb accumulation capacity per plant. Sulphur enrichment of A. dioica was much higher than other species. Enrichment coefficients of S, Cu and Pb of P. heterophyllurn were not high, but the transfer coefficients were much higher than other species.
