摘  要:
运用地统计学方法对合肥大兴镇地区土壤重金属含量的空间结构特征进行了定量描述,并探讨了研究区域内重金属空间结构的主要影响因素。结果表明:研究区域土壤中Cu、Pb、Zn、Cd、As、Hg等6种重金属元素的实验变异函数理论模型拟合效果较好。六种重金属具有明显的空间变异性,受人为影响较大。研究区内众多的工矿企业及农业活动是造成重金属累积的主要原因。同时,研究区存在重金属元素混合污染的潜在危害。

摘  要:
By using the geo-statistical methods,the quantitative description of the spatial structure characteristics of soil heavy metals in Daxing district of Hefei city were given and the main factors for the spatial structures were investigated.The results showed that the experimental variogram models of soil Cu,Pb,Zn,Cd,As and Hg were better.The six heavy metals had significant spatial variability,influenced by the human activities greatly.In the area,the large number of industrial and mining enterprises and agricultural activities were the main reasons for the heavy metals accumulation in the soil.At the same time,there is a potential risk of mixed noxious contamination of heavy metals.
