| 摘 要： | 以西安污灌区典型大棚菜地和附近农耕地土壤为研究对象,在不同土壤剖面上对重金属As、Cr、Cu、Pb、Zn和Ni的分布进行了测定和分析。结果表明:在0~20 cm土层农耕地土壤重金属Cr、Cu、Pb、Zn、Ni的含量均高于大棚菜地,分别高出53.1、16.7、20.5、151.2和3 mg/kg,同农耕地相比,温室大棚更有利于土壤表层重金属的迁移,且对Zn、Cr、Pb、Cu等元素的迁移程度较明显。认为在西安污灌区发展大棚花卉,可以有效减少污灌区土壤表层重金属的含量。

| Abstract: | The contents of soil heavy metal in Xi''an area were investigated. The typical cultivated field soil profile and the typical greenhouse soil profile were chosen as the research objects and collected samples of soil. The total con-tents of As, Cr, Cu, Pb, Zn and Ni in soil samples collected from the area were analyzed. The results shown that the
contents of Cr, Cu, Pb, Zn and Ni in the profile of field cultivated soil in 0~20 cm was were higher than that of in the
greenhouse soil, over53.1, 16.7, 20.5, 151.2 and 3 mg/kg respectively. The greenhouse were more beneficial the
heavy metals'' transfer in horizon. It is obvious that the migration conversion degree to the soil heavy metals such as Zn, Cr, Cu and Pb. This paper reckons putting forward to develop the greenhouse flowers cultivation to control soil heavy metals pollution maybe is a profitable way for sustainable development of agriculture in the future. |
