摘要
为了揭示酸性土壤重金属含量与其影响因素间的作用关系,为土壤重金属的污染控制和治理提供参考,以湖南壶瓶山自然保护区土壤为研究对象,根据野外调查和实验室监测结果进行统计。结果表明:重金属污染程度由高到低依次为As>Ni>Pb>Cu>Cd、Zn>Cr>Hg,空间分布不均匀程度由大到小依次为Cd>As>Pb>Zn>Cu>Cr>Ni>Hg;不论是林地与耕地、黄壤与红壤、潮湿与润湿土壤,分布不均匀程度较高是As、Cd、Pb、Cu,分布较均匀的是Hg、Ni。
In order to effectively reveal the effect of influencing factors on heavy metals and provide scientific basis for controlling heavy metals pollution,Hu ping shan is studied through sampling outside and analysis in laboratory,.The results show that the degrees of pollution order is As Ni Pb Cu Cd、Zn Cr Hg,the uneven of distribution is Cd As Pb Zn Cu Cr Ni Hg in space.But As,Cd,Pb and Cu is higher uneven distribution in forest and cultivated land,yellow and red soil,damp and moist soil;Hg and Ni is evener.
