摘要:为了解滕州地区表层土壤重金属污染状况及其来源，以滕州地区土壤中As， Cd， Cr， Cu ， Hg，Ni，Pb ，Zn等元素含量为研究对象，在对深、表层土壤样品数据进行正态、对数正态分析的基础上，选取Al₂O₃为参比指标，获取重金属背景值，对研究区土壤重金属的富集因子进行统 计，评价研究区重金属污染等级；结合土壤重金属数据的Pearson相关性分析和因子分析，解析重金属的污染来源。研究结果表明：研究区表层土壤重金属污染等级大多数为无污染和轻微污染，在部分区域Hg和Cd达到中度污染，Hg甚至达到强烈污染，主要分布在中部、南部和东南部；研究区点状污染分布相对突出，交通沿线污染等级较高，表层土壤重金属主要源于自然成土演化及交通运输、化肥农药、工矿业排污等人为因素。

Abstract:In order to understand the contamination and sources of heavy metals in the surface of Tengzhou area ，the contents of As，Cd，Cr，Cu，Hg，Ni， Pb and Zn in the soil of Tengzhou area were studied. On the basis of normal and log-normal analysis of deep and surface soil samples data. Al₂O₃ was selected as the reference index to obtain the background value of heavy metals， and the enrichment factors of soil heavy metals in the study area were counted to evaluate the heavy metal pollution level in the study area. Based on Pearson correlation analysis and factor analysis of soil heavy metal data， the pollution sources of heavy metals were analyzed. The results showed that the pollution grade of heavy metals in the topsoil was mostly non-polluted and slightly polluted ，while Hg and Cd were moderately polluted in some areas， among which Hg was even seriously polluted. Heavy metal pollution had reached moderate level and above， which mainly distributed in the central， southern and southeastern regions. The distribution of point pollution in the study area was relatively prominent， and the pollution level along the traffic was relatively high. The heavy metals in the topsoil of the study area mainly originated from natural soil-forming evolution factors and human-induced pollution factors such as transportation ，chemical fertilizers and pesticides， industrial and mining sewage.
