| 摘 要： | 研究了江西省乐平市乐安河上游岸边的兰村洲段的土壤主要重金属Cd、Cu、Zn、Pb的污染状况。结果表明:该地区重金属Cu、Cd污染严重;Zn、Pb的含量不造成污染。从空间污染特征看,在离河道15,50,75 m处污染较严重,5 m处中层土含量较高;Cu随距离河道越远,含量越少,在离河道5 m表层土及下层土污染指数较高,污染较严重。因此,该地区比较适合选取能忍耐并富集Cu和Cd且根系较深的的植物进行植物修复来治理土壤重金属污染。

| Abstract: | The pollution situation of heavy metal in soil was studied.The sample soil was from Lan country,the upstream of Lean River.The results showed that the region was polluted seriously with heavy metals Cu and Cr,and the content of Zn and Pb in soil did not cause pollution.In the places of 15,50,75 m away from the shore of river,Cr caused more serious pollution,which pollution index was higher in the middle soil of 5 m place away the river.The farther the place away from the river was,the less Cu content was.In the place of 5 m from the river,the surface soil and subsoil pollution index were higher than the middle soil,and with more serious polluted.So the plants,which can endure the concentration of cadmium and copper,were more appropriate to be planted in this place because of their deep root system.So phyto-remediation was the better way to control heavy metal pollution here. |
