摘要
环境地球化学基线是将某一地区或数据集合作为参照时某一元素在特定物质中(土壤、沉积物、岩石)的自然丰度,并可以表述为区分地球化学背景和异常的单一的极限,是区分自然的和人为的环境影响的重要参照,是进行环境污染状况分析的基础。因此采用科学合理的方法确定土壤环境地球化学基线具有重要意义。采用统计学方法建立了矿山表层土壤中重金属元素As、Cd、Co、Cr、Cu、Hg、Mn、Ni、Pb、Zn的环境地球化学基线,为下一步评价矿山表层土壤的重金属污染打下了良好的基础。
Environmental geochemical baseline is the natural content of an element in given material （soil,sediments,rock）, when a particular district or data was used as a reference, which can be expressed as the single limit between the geochemical background and anomalies, it is the basis of the analysis of the environmental situation. Using statistically analyzing method this thesis studies the environmental geochemical characteristics of 10 heavy metal elements which are As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn in the topsoil of the study area, and makes ceaain the environmental geochemical baseline of heavy metal elements. It laies a good foundation for environmental impact assessment in Yanzhou coal mining area.
