| 中文摘要: |
| 在昌化铅锌矿尾矿库区内采集优势自然生植物及其根系周边的土壤，分析土壤样品重
金属含量特征，运用单因子污染指数法、内梅罗综合污染指数法和潜在生态危害指数法对土壤进
行重金属污染评价，并通过富集系数评价自然生植物对重金属的富集能力。研究结果表明：（1）尾
矿库区内四种重金属的污染程度由强到弱依次为：Cd>Pb>Zn>Cu；（2）昌化铅锌矿尾矿库区整体处
于极强生态危害水平；（3）尾矿库区内的不同种自然生植物对同一种重金属的富集能力不同，同一
种植物对不同种重金属的富集能力不同；（4）仙人掌是尾矿库区内富集系数最高、最稳定的自然生
植物。研究结果对昌化铅锌矿尾矿库区土壤重金属污染的治理有参考意义。 |
| 英文摘要: |
| Dominant natural plants and soil around their roots were collected from wasteland soils in Changhua lead-zine
mine in China, and the feature of heavy mental content in soil samples was analyzed, using the single factor pollution index
method, the comprehensive index method and potential ecological harm index method, to evaluate the soil heavy metal pol⁃
lution, and to evaluate the enrichment capacity of heavy metals of plants by calculating the transfer coefficients. The results
showed as follows: (1) the pollution levels of each heavy metal in the study area were Cd>Pb>Zn>Cu; (2)Changhua leadzinc mine tailings reservoir area is in a strong ecological damage level; (3) Different Nature plants have different enrichment
factor to the same heavy mental and the same nature plan has different enrichment factor to different heavy mental in leadzinc mine; (4) Opuntia stricta has the highest enrichment factor and is the most stable palnt in the tailings reservoir area of
lead-zinc mine of Changhua. In a word, the study has significance in dealing with mental pollution of soil in Changhua
lead-zine mine. |
