摘要
研究了大冶铜绿山矿区海洲香薷 ( Elsholtzia haichowensis)及其群落中几种主要植物 Cu、Mn、Zn、Cd、Pb的累积分布 ,植物与土壤元素、Cu矿的关系 ,并对海洲香薷的重金属耐受性、铜矿的指示作用作了初步探讨。结果显示 :海洲香薷植物中的元素表现为 Cu>Mn>Zn>Pb>Cd。其中 Cu、Mn、Pb元素含量表现为根 >叶 >茎 ,Zn、Cd表现为叶 >根 >茎。和其它植物相比 ,海洲香薷中的 Cu、Mn、Cd含量均高于其它植物 ,是其它植物的 1～ 1 0倍。海洲香薷与土壤元素关系中 ,Cu的相关性最显著 ,其次为 Pb。海洲香薷集中分布于矿区内含 Cu较高的土壤上 ( 1 64 5～ 8950μg/g) ,其分布与 Cu密切相关。
Element accumulation and distribution of Elsholtzia haichowensis and some dominant plants in E. haichowensis community were studied in Daye Tong Lushan copper mine area. Relations were analyzed among plants, soils and copper mine. The copper tolerance of E. haichowensis and its indication function were discussed. Results showed that metal element contents of E. haichowensis in sequence were :Cu > Mn > Zn > Pb > Cd. Contents of Cu, Mn, Pb of the plant in sequence were :root >leaf>stem, Zn and Cd : leaf >root >stem. Compared with that of other plants in E. haichowensis community, contents of Cu, Mn and Cd in the plant were higher, and were as much as 1～10 of other plants. There was significant corelation in Cu contents between plants and soils, and the next was in Pb contents. E. haichowensis distributes in higher copper soil(1645～8950μg/g) in copper mine area. There was closely relation between plant distribution and soil copper. It had higher copper tolerance in the plant.
