山东省博山区土壤元素分布特征研究

通过对山东省博山区土壤元素背景值状况的计算和研究，统计N、I、V、F、Cd、Cr、Hg、Co、K、P、Mn、Mo、Ni、B、Pb、As、Cu、Se、Zn、Ge、Sb、Fe、有机质等28种指标的表层土壤地球化学特征参数，查明了土壤元素分布特征、富集贫化规律，对其与全国、全省同类参数的差异进行了分析。结果表明，含量的显著特征是高Mn、F、P、Sr,而低Hg；大部分元素在表层土壤中的含量继承了土壤母质的成分特征，但Cd、Cr、Hg等受人为活动和污染源的作用在表层土壤中明显富集。区内土壤环境质量水平总体较好，部分重金属元素分布受地质背景控制，污染地块面积小。研究区Se、Zn、Ge等元素丰富，特色土地资源具有良好的开发前景。

Distribution characteristics of soil elements in Boshan District, Shandong Province

Based on the calculation and study of the background values of soil elements in Boshan District,Shandong Province,the surface soil geochemical characteristics parameters of 28 indexes, such As N, I, V, F, Cd, Cr, Hg, Co, K, P, Mn, Mo, Ni, B, Pb, As, Cu, Se, Zn, Ge, Sb, Fe and organic matter, were counted. The distribution characteristics, enrichment and dilution of soil elements were found out, and the differences between soil elements and similar parameters in China and the whole province were analyzed. The results show that the content of Mn, F, P, Sr is high, but Hg is low. The contents of most elements in surface soil inherit the composition characteristics of soil parent material, but Cd, Cr, Hg and other elements are obviously enriched in surface soil by human activities and pollution sources. The soil environmental quality in the region is generally good, and the distribution of some heavy metal elements is controlled by the geological background, and the contaminated plot area is small. The study area is rich in Se, Zn, Ge and other elements, and the characteristic land resources have a good development prospect.
