摘要: 为了研究香蒲中重金属的分布规律,选取皂河人工湿地和皂河人工湿地示范基地作为研究场地,以两个人工湿地中的香蒲为研究对象,通过测定香蒲不同部位中重金属铜(Cu)和铬(Cr)的含量,分析香蒲中Cu和Cr的空间分布规律。结果表明,香蒲能较好地吸收Cu,重金属在香蒲根中的含量最多,其次是茎,叶中重金属含量最少;重金属Cu在香蒲中的含量最多,香蒲中Cu的转移系数较大,通过季节性的收割从而使植物中重金属得以去除;两个人工湿地的香蒲都能较好地去除重金属Cu。

Abstract: To explore the distribution of heavy metals in the cattails, the Zaohe constructed wetland and the Zaohe river constructed wetland demonstration base were selected as the research site. The cattails in the two artificial wetlands were taken as the research object, and the concentrations of copper and chromium in different parts of cattails were determined. The results showed that the cattail can absorb Cu well, and the content of heavy metals in cattail roots is the most, followed by the stem and leaves; The content of Cu is the highest in cattail, and the transfer coefficient of Cu in cattail is large, so the heavy metal in plants can be removed through seasonal harvesting; The cattails in two constructed wetlands can better remove the heavy metal Cu.

Key words: constructed wetlands, heavy metals, cattail, distribution
