摘要
为了掌握自然保护区土壤中重金属的分布情况和污染现状,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,分析重金属的空间分布特征;采用单因子和综合因子指数法评价土壤中重金属污染现状。结果表明:壶瓶山自然保护区土壤中八种重金属Cd、Hg、As、Cu、Pb、Cr、Zn、Ni,除Hg和Cr未受污染外,其余6种均受到轻污染;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。
In order to grasp the heavy metal of distribution and pollution in soil natural protectorate, Huping shan is studied through sampling outside and analysis in laboratory, the degrees of pollution is evaluated with single-facter pollution index (SPI) and comprehensive pollution index (CPI). The results show that the degrees of pollution of the rest 6 heavy metal is light except Hg and Cr, besides its 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.
