摘 要:研究了太原盆地土壤中8种重金属元素As,Cd,Cr,Hg,Ni,Pb,Zn,Cu的来源及分布规律,首次计算了太原盆地区域土壤背景值,分析了盆地中重金属元素的污染状况;认为Hg,Cd,As的污染情况最为严重。用太原市和太原盆地的深、浅层数据作出8种重金属元素的多重分形图,对8种重金属元素在生态环境中的影响作用进行了统计分析,总结了重金属元素的分形规律,得出各影响因素的相对重要性。In this paper, the sources and distribution law of 8 heavy-metal elements Cd, Cr, Hg, Ni, Pb, Zn,As,and Cu in the soil of the Taiyuan Basin were researched. The works and the achievements are as follows:The background values of the soil in Taiyuan basin were calculated first and the pollution status of the soil in the basin analysed suggesting the most serious pollution of Hg,Cd, As. Then the multifractal pictures of 8 heavy-metal elements have been drawn under pairs of logarithm coordinates by using the data of shallow and deep layers of the soil in the city and the basin. Environmental influences of the 8 heavey metals are statistically analysed, fractal pattern of the heavey metals summerized giving their relative influence factors.
