| 摘 要： | 研究了九龙江下游地区７种重金属元素（Ｚｎ、Ｃｄ、Ｃｒ、Ｍｎ、Ｐｂ、Ｎｉ、Ｃｕ）在土壤－蔬菜系统中的分布、积累规律，土壤污染指数，土壤和蔬菜的Ｃｄ／Ｚｎ比值，蔬菜对重金属元素的吸收率、富集率．结果表明该区土壤中Ｃｕ、Ｚｎ、Ｃｄ三种元素污染较严重，多个样点的土壤污染指数大于１，而元素Ｐｂ仅两个样点的污染指数接近于１，区内样点的Ｃｄ／Ｚｎ值均小于１％，Ｃｄ在蔬菜体内积累未达到危害程度，蔬菜对重金属元素吸收率、富集率随不同样点而异．

| Abstract: | The regularity of distribution, translocation and accumulation of heavy metals(Zn Ni Mn Cu Pb Cd Cr)from vegetable-soil system in the Jiulong river valley have bean investigated. The result of the experiments shows that soil pollutions of Cu,Zn and Cd are more serious. Their pollution indexes of many zones reached up to above >1,and two zones pollution indexes of Pb access to 1. The ratio of Cd/Zn of all zones was less that <1 y6. The content of Cd in vegetable doesn't reaeh dangrous degree. Vegetables in different environments don't have similar absorption and enrichment ratios for heavy metals. |
