| 摘 要： | 城市垃圾填埋场的生态修复问题越来越受到重视，选择合适的封场植被对生态恢复至关重要。本研究对上海市桃浦垃圾填埋场的土壤和29种优势植物的重金属含量进行检测，结果显示，该填埋埋场土壤呈现Zn和Cd的中度复合污染。在研究的优势植物中，杨树、雪松和夹竹桃吸收Zn的能力较强，杨树、紫薇、金丝桃吸收Cd的能力较强。荆芥表现为重金属Zn的富集型植物；龙葵表现为重金属Cd的富集型植物；麦冬和狗尾巴草则表现为重金属的根部囤积型植物。可综合选择这些植物用于城市垃圾填埋场的植物修复和植被恢复。

| Abstract: | The ecological restoration of site is becoming more and more important. The phytoremediation is a popular way for the ecological restoration of urban landfill at present. So the Shanghai Taopu Landfill the only one landfill sited at the urban in Shanghai was chosen to be the experimental field. Through analyzing the heavy metal ion content of soils and 29 kinds of dominant plants sampled on the Shanghai Taopu Landfill,results showed that the landfill is moderately contaminated with Zn and Cd. Populus, Nerium oleander, Cedrus deodara had the strong ability to absorb Zn in landfill. Populus, Lagerstroemia indica and Hypericum monogynum can enrich much more cadmium. Fineleaf schizonepeta were suggested to be the Zn accumulation plant for ecological recovery. Solanum nigrum was tested to be the Cd accumulation plant. O.japonicus(L.f.)Ker-Gawl. and Setaira viridis (L.) Beauv are revealed to be root compartment plants. |
