| 摘 要： | 1 引 言土壤重金属污染一直是环境污染问题之一 ,而且土壤中的重金属污染具有严重性、长期性和广泛性的特点[1 ,6] .但常规的一些物理化学方法因费用过高、对土壤性质破坏等一系列问题而难以广泛应用 ,植物修复为重金属污染带来了希望[5,7,9,1 3] .植物修复主要是基于重金属超积累植物 (ｈｙｐｅｒ ａｃｃｕｍｕｌａｔｏｒ)的研究而兴起的 .超积累植物是指地上部分能富集重金属占干重的 1 0 0ｍｇ·ｋｇ-1 (Ｃｕ、Ｐｂ、Ｃｄ)或 1 0 0 0 0ｍｇ·ｋｇ-1 (如Ｚｎ)的一类植物[2～ 4,8] .在过去 2 0年内 ,已报道的超积累植物已有 4 0 0余种 …

| Abstract: | Plant species distributing in three Cu-mining area were investigated, and Cu concentrations in soils and plants were analyzed. The results showed that Cu ore deposit mostly was distributed at the altitude of about 630 m. Elsholtzia splendens and Rumex acetosa were distributed only on the Cu ore deposit or the place with high Cu concentration, and the maximum Cu concentrations in these two plants were 1060 mg.kg-1 DW and 1006 mg.kg-1 DW, which reached the critical of hyperaccumulator. Cu accumulations in Elsholtzia splendens and Rumex acetosa were positively and closely correlated with Cu concentration in soil. |
