| 摘 要： | 从地球化学特征探讨土壤重金属及其与植物中重金属污染的相互关系。通过生物地球化学的方法,测定土壤与植物重金属含量。野马川和妈姑镇废弃地均受到重金属严重污染,Zn、Cd和Pb的污染相对严重,含量特征表现为ZnPbCuAsCd。植物体内重金属离散程度顺序为ZnPbCuAsCd,与土壤重金属含量顺序一致。植物中重金属元素与土壤中重金属元素的含量呈正相关关系(P0.05)(元素As除外)。土壤受重金属污染,优势植物节节草(Hippochaete hiemale)和大叶醉鱼草(Buddleja davidii)中重金属含量最高,在重金属污染区生态恢复过程中可作为重点推荐植物。

Correlation Analysis on Heavy Metal Pollution and Advantages of Plant from Wasteland of Artisanal Lead-zinc Melter by Indigenous Method |

| Abstract: | The relationship between soil and plant heavy metal pollution were discussed from the geochemical characteristics. By the method of biogeochemistry,determination of heavy metal content in soil and plants. The results showed that waste land of lead-zinc smelting were serious heavy metals pollution in mine spoils of Yemachuan and Maguzhen town, every mine about the pollution of Zn,Cd and Pb were the most serious, and the content characteristic of heavy metals in the order: Zn>Pb>Cu>As>Cd. The order of discrete degree of heavy metals in plant was Zn>Pb>Cu>As>Cd, and in accordance with soil heavy metal content in order. Heavy metals content in plants were positively correlated with the content of heavy metals in soil (P<0.05) (in addition to the As elements). Soil polluted by heavy metals. The advantages plants of Hippochaete hiemale and Buddleja davidii had the highest heavy metal content. In the area of heavy metals polluted could be run as the key recom-mendation plants in the process of ecological restoration. |
