摘　　要：指出了城市垃圾填埋场对环境的破坏日益严重,选择合适的植被对其进行生态修复尤为重要。针对实际测定了保定市某垃圾填埋场13种优势植物的重金属含量。结果显示:柳树、杨树、榆树、紫穗槐、龙葵和商陆对Cd的吸收能力较强,可作为重金属Cd的修复植物加以推广;柳树、杨树、芦苇、狗尾草、龙葵、商陆、藜吸收Zn的能力较强;芦苇、爬山虎、商陆吸收Cu、芦苇吸收Cr的能力较强;榆树、爬山虎、狗尾草对Pd具有较强的吸收富集能力;可认定龙葵为Cd和Zn的超富集植物、爬山虎为Pb的超富集植物。因此,这些植物可用于城市垃圾填埋场重金属污染的修复治理。The damage to the environment caused by municipal landfills is becoming more and more serious. The phy-toremediation is a popular way for the ecological restoration of urban landfills at present. This research analyzed 13 dominating plants in a municipal landfill in Baoding which contain heavy metal ion content. Results showed that Salix babylonica,Populus, Ulmus pumila, Amorpha fruticose, Solanum nigrum and Phytolacca acinosa had a very strong capability to absorb Cd in landfills. They can be used as phytoremediation of heavy metal Cd. Similarly, Salix baby- lonica, Populus, Phragmites australis, Setaira viridis, Solanum nigrum, Phytolacca acinosa and Chenopodium album are good at absorbing Zn, Phragmites australis, Parthenocissus tricuspidata and Phytolacca acinosa can absorb Cu, Phragmites australis can absorb Cr too. While Ulmus pumila, Parthenocissus tricuspidata and Setaira viridis are good at absorbing Pd. Solanum nigrum was tested to he the Cd and Zn accumulation plant. Parthenocissus tricuspidata was tested to be the Pd accumulation plant. These plants can be used as useful remediation of heavy metal pollution in municipal landfills.
