摘　　要：针对陕西省某金矿区农田土壤重金属的含量,进行空间变异性研究。使用经典统计学分析数据,结合地统计学软件和ARCGIS软件采用泛克里格插值法对重金属元素含量进行空间插值。通过分析得出:Cr的分布较均匀,符合国家一级环境质量标准;Zn在西北向无明显变异,东南部含量相对集中,主要受区域环境因素影响,与该地区土壤沉积和矿业活动有关。A study on spatial variation of soil heavy metals＇ content was carried out for a goldfield agricultural area in Shannxi province.Classical statistics was used to analyze data,and combined with geo-statistics and ARCGIS softwares,Kriging method was adopted to realize spatial interpolation for heavy metals＇ content.The results showed that chromium was well-distributed and in line with the national primary environmental quality standards,and zinc had no significant variation in the northwest,but relatively concentrated in the southeast.It was mainly result from regionally environmental factors and associated with the soil deposits and mining activities in this region.
