研究了湖南郴州某铅锌选矿厂铅锌矿渣污染下土壤重金属的不同化学形态含量、土壤化学性质和真菌群落的多样性。结果表明:与湖南省重金属修复地方标准相比,采样区4种重金属Zn、Pb、Cd、Cu的污染程度依次降低;同种重金属不同化学形态之间比较,铅铁锰氧化态、锌醋酸提取态、镉醋酸提取态、铜残渣态含量较高;重金属污染显著改变真菌群落的组成和结构;敏感性真菌(球囊菌门(Glomeromycota))的相对丰度随重金属污染程度的增加而降低,而耐受性真菌(子囊菌门(Ascomycota)、担子菌门(Basidiomycota)、被孢囊门(Mortierellomycota)、被孢菌属(Mortierella)、青霉菌属(Penicillium)和镰刀菌属(Fusarium))的相...

In the present study,we investigated different chemical forms of soil heavy metals,soil chemical properties,and fungal diversity and composition for the contaminated soil collected from the tailings in Chenzhou Pb-Zn mining area,Hunan.The results showed that,compared with the Hunan local standard of heavy metal remediation,the polluted extent of the four kinds of heavy metals in soil samples was as follows:Zn >Pb >Cd >Cu.Compared with different chemical forms of the same heavy metal,it was found that the contents of Fe-Mn oxidation fraction of Pb,HOAc extractable fraction of Zn,HOAc extractabl...
