| 摘 要： | 通过盆栽试验评价3种木本植物紫穗槐、桤木和黄连木修复铅锌矿和铜矿尾矿的潜力。结果表明,150d后3种植物在矿砂中都能生长,其中黄连木在铅锌矿砂中生长受到明显抑制,桤木的叶绿素含量显著降低。3种植物的根系发育在2种矿砂中没有受到显著抑制。重金属在3种植物组织中的含量为17.66 -55.36 mg/kg (铜)、2.67-196.00 mg/kg(铅)、58.93-333.67 (锌,铅锌矿砂)和49.20-199.33(锌,铜矿砂)。3种植物的生物富集系数(BCF)和转移系数(TF)值都小于1。60d后,桤木和黄连木叶片的叶绿素荧光参数与对照相比没有显著变化,PSⅡ的最大量子产量有下降的趋势。重金属胁迫后显著增加Mg、Fe、Cu在功能叶的含量,显著地降低Mn的含量。因此可利用固氮植物紫穗槐在尾矿区造林和修复。 |

| Abstract: | Mine tailings are known to have environmental perniciousness due to their high concentrations of heavy metals.Phytoremediation can provide a cost-effective,long-lasting and aesthetic solution for the reclamation of mine tailings.However,revegetation on mine tailing areas is a difficult practice because of toxicity of heavy metals and low nutrient levels.As a result,most tailings disposal sites are devoid of vegetation.Hence,plant species with barren tolerance and excess metal tolerance are required.To date,... |
| Keywords: | woody plants mine tailing tolerance chlorophyll fluorescence parameters root |
