| 摘 要： | 利用原子吸收法测定黔西南红土型金矿硬叶小金发藓(Pogonmon neesii(C.Muell)Dozy)植株及其土壤中的Au、Pb、Cu、、Zn、Ca、Mg、Hg和As等8种金属元素含量,并分析它们之间的相关性及植物对金属的富集能力.结果表明:硬叶小金发藓体内的金属元素含量普遍较高,对不同金属元素的吸收、富集具有较大的差异,Ca-Mg呈极显著正相关,Cu-Zn、Hg-As呈显著正相关.该植物对Hg和As均具有强烈的富集作用.

| Abstract: | The contents of eight metal elements,such as Au,Pb,Cu,Zn,Ca,Mg,Hg and As in Pogonatum neesii(C.Muell.) Dozy and soil on Lateritic Gold Deposit in Southwest Guizhou Province were analysed by Atomic Absorption Spectrometry,and the correlationship between plant and metal elements, and the accumulation of the moss to metals were further discussed.The results showed that the metal contents in P.neesii were higher than in soil,and the accumulation capacity of the plant to different metals varied greatly. Ca-Mg sh... |
