摘 要：
以潼关县黄金生产区及附近不同地区生长的6种蒿类植物:叉枝蒿(Artemisia divari-cata(Pamp.)Pamp)、青蒿(Artemisia annua L.)、水蒿(Artemisia selengensis)、茵陈蒿(Artemisiacapillaries)、莳萝蒿(Artemisia anethoides Mattf.)、艾蒿(Artemisia argyi)为试材,测定并分析蒿类植物中的铜含量,以便确定建立人工生态系统的植物种类。结果表明:同种植物对铜的吸收能力会随着根际土壤中铜含量的增加而增加;9个样地中青蒿-XI对铜的吸收效果最好,富集系数为0.92,铜主要储存在叶片中;艾蒿①对铜的富集能力也相对较高,富集系数为0.87;2个样地中的水蒿叶片中富集铜的能力均较强,水蒿-13为78.32mg/kg和水蒿①为69.21mg/kg。

摘 要：
The author choosed six kinds of Artemisia plants as subject investigated around the golden mineral at tongguan county,including Artemisia divaricata(Pamp.) Pamp,Artemisia annua L.,Artemisia selengensis,Artemisia capillaries,Artemisia anethoides Mattf.and Artemisia argyi.Through determining the content of heavy metal Cu in different plants,the author establishes the plant species of artificial ecosystem.The results showed that the absorbing capacity for the same plant increases with the Cu content increasing.Among six kinds of plants in nine different places,the Artemisia annua L.-XI had the best absorbing capacity to Cu,the concentration coefficients was 0.92,and Cu was mostly stored in plant leaves.Respectively Speaking,Artemisia argyi ① also had higher concentration coefficients and it's 0.87.The concentration capacity of Artemisia selengensis leaves in two places were higher,and it was 78.32 mg/kg for Artemisia selengensis-13 and 69.21 mg/kg for Artemisia selengensis①.
