针对洞庭湖湿地土壤Cd污染严重的现状,对湖区滨岸带8种优势植物的Cd富集特征及其修复效果进行了分析。结果表明,蒌蒿（Artemisia selengensis）对Cd表现出显著的富集特征,对Cd污染的修复效果好,是洞庭湖土壤Cd污染的理想修复材料;南艾蒿（Artemisia verlotorum）对Cd污染具有较好的修复效果,可作为湿地土壤Cd污染修复的备选材料;芦苇（Phragmites australis）和南荻（Miscanthus lutarioriparius）植株的根部对Cd的积累量较高,具有良好的稳定修复效果,且由于二者地上部生物量大、能被连续刈割的特点,对洞庭湖湿地Cd污染治理起到一定的促进作用。

Aiming at the present serious situation of soil Cd pollution in Dongting Lake wetland, this paper analyzed the Cd enrichment characteristics and remediation effects of eight dominant plant species growing in Dongting Lake area. Among the eight dominant plants, Artemisia selengensis presented a notable capacity to absorb Cd from lake soil, and had good effect in the remediation of Cd pollution, being an ideal plant for the bioremediation of Cd-polluted soil in Dongting Lake wetland. A. verlotorum had acceptable effect in the remediation of Cd pollution, being able to be selected as a potential ...
