摘    要:以绥宁河为例,通过研究凤眼莲各部位对重金属的吸收和吸附作用。探讨水生植物对改善城市内河水环境的重要性。实验数据表明。在凤眼莲对重金属的富集作用中,根部的贡献远大于茎叶部,根部对重金属的吸收量是茎叶部的几十至几百倍。此外,根部吸附作用对水环境中重金属的去除也起了相当重要的作用。

关 键 词:凤眼莲  富集作用  重金属  吸收  吸附  根部  茎叶部  水环境  水治理

Abstract:In this paper, heavy metal content in different parts of Eichhornia crassipes Solm has been analyzed to show the important role of hydrophyte in improv ing water environment of urban creeks. The experimental data showed that in the case of concentration of heavy metal, contribution of root system was higher than that of leaf and stem, and in addition, adsorption of root system played an important role in removing heavy metal in water environment.
Keywords:Eichhornia crassipes Solm Concentration Heavy metal content Absorption Adsorption Root system leaf and stem
