摘要:
在太白山自然保护区,依据土壤类型选择典型样地取样，在室内分析的基础上，研究了太白山自然保护区土壤中6种重金属元素的含量及其分布特征。结果表明太白山自然保护区土壤6种重金属平均含量大小顺序为Zn>Cr>Pb>Cu>As>Cd。与国家《土壤环境质量标准》（GB15618-1995）一级标准相比较，保护区土壤质量总体上保持着自然背景水平；随着海拔的升高，Zn、Cr、Pb含量呈升高趋势，Cu、Cd含量呈下降趋势，As含量变化不大，分布较均匀；重金属元素在各类型土壤剖面中分布不同，在褐土剖面中主要表现为表层富集和淋溶，棕壤、暗棕壤和森林草甸土剖面下层元素富集现象较明显，而高山草甸土剖面中元素的垂直分布不明显，分布较均匀。
Abstract:
Based on field sampling and indoor analysis,the contents of 6 heavy metals in soils of Taibaishan Nature Reserve were studied.The results showed that the contents of the heavy metals were Zn>Cr>Pb>Cu>As>Cd. Compared with the first class standard of National Environmental Quality Standard for Soil, contents of 6 heavy metal elements are normal, the soil quality in Taibaishan Nature Reserve was good.Along the altitudes from foot to top of the mountain, the contents of Zn,Cr,Pb,Cr increased, the contents of Cu and Cd decreased, the variation of As content was the lowest. The distribution of the heavy metals in soil profiles was different. In cinnamon soil, the heavy metals mainly accumulated on the upper horizon and there was eluviation. In the profiles of brown earth, dark brown earth and forest meadow soil, the heavy metals were mainly accumulating below the surface layer. In alpine meadow soil, the vertical variation of the heavy metal contents was not significant.
